Most HPA engines give you a pneumatic valve and a basic board for dwell and rate of fire. The PULSAR S drops a full TITAN II or ASTER II Bluetooth unit into the engine itself, so the trigger reads position optically rather than through a switch, and everything is configurable from your phone.\u003c\/p\u003e\n\u003cp\u003eIn practice that means a trigger you can genuinely tune. Fifty levels of sensitivity inside the first millimetre of travel lets you set a hair trigger that breaks almost on contact, or deliberately lengthen it for milsim. Binary mode fires on press and release. Burst is configurable from two to nine rounds. Rate of fire runs from 1 to 100 RPS, all adjustable live through the GCS app without opening the gun.\u003c\/p\u003e\n\u003cp\u003eIt is also remarkably small — 88mm long and 75g, the smallest single-solenoid HPA engine made.

Convert a P90, M14, PDR, Thompson or similar to HPA without losing the platform you love. Comes with Wolverine's Gen 2 Premium FCU and everything you need to install.\u003c\/div\u003e\n\u003cp\u003eMost HPA engines on the market are designed for centreline-nozzle AEGs — the M4-style platform where the air nozzle sits directly behind the hop-up unit on the bore centreline. That works for around 80% of AEG conversions, but it leaves platforms like the P90, M14, PDR, Thompson and F2000 stuck on AEG performance because their gearboxes feed BBs off-centre. The HYDRA exists to solve exactly that problem.\u003c\/p\u003e\n\u003cp\u003eThe HYDRA Gen 2 inherits the hybrid open\/closed-bolt poppet system that made the INFERNO Gen 2 the benchmark drop-in HPA engine of the last decade. What's different is the offset-nozzle architecture: an independent poppet and nozzle layout that delivers a centreline-quality air seal even when the BB feed path runs off-axis. A front bushing plate added in Gen 2 stabilises the nozzle during firing for tighter, more repeatable groups — matching the consistency Wolverine's centreline engines achieve in M4 builds.\u003c\/p\u003e\n\u003cp\u003eEach HYDRA Gen 2 kit ships with the engine, the Gen 2 Premium FCU, and all the platform-specific hardware you need to drop into your specific AEG. Choose the platform from the variant selector. ROF runs 5–35 RPS, though some platforms (particularly the M14's spring-fed magazine) won't hit the top of that range because of mechanical feeding limits — this is normal and documented by Wolverine.\u003c\/p\u003e\n\u003cp\u003eIf you're converting a P90 the HYDRA opens up a category of HPA SMGs that simply isn't available elsewhere. The same applies to designated-marksman M14 builds, which become genuinely viable as DMRs once they're running on HPA. The Thompson variant is for collectors and themed-loadout players who want the look without the AEG compromises. PDR support covers Magpul-style PDR-C platforms.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eEngine architecture\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHybrid open\/closed-bolt poppet — same as INFERNO Gen 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eNozzle geometry\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eOffset (for platforms with off-axis BB feed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePlatforms supported\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eP90, M14 (TM \u0026amp; G\u0026amp;G), PDR, Thompson — select variant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFCU included\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWolverine Gen 2 Premium FCU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRate of fire\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e5–35 RPS (platform-dependent — some feeds limit max ROF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWiring\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eIncludes platform-specific harness\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFront bushing plate\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAdded in Gen 2 — improves nozzle stability and shot consistency\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePower\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eStandard HPA tank and regulator (sold separately) plus small LiPo for FCU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#fff8dc;border-left:4px solid #f4b400;padding:10px 14px;border-radius:0 6px 6px 0;font-size:13px;margin:14px 0;\"\u003e⚠ \u003cstrong\u003ePlatform selection is critical:\u003c\/strong\u003e the HYDRA is platform-specific — each variant ships with hardware tailored to that AEG.

Approximately 1,000 shots per 13ci tank.\u003c\/strong\u003e The WRAITH X has a built-in STORM Category 5 regulator. It runs HPA from the included 13\/3000 tank, or CO2 from 12g or 33g cartridges concealed in the buffer tube — both options fully lineless.\u003c\/div\u003e\n\n\u003cp\u003eFor players who want the performance of HPA without the trailing grip line, the Wolverine WRAITH X is the definitive solution. It routes your entire air supply internally through the stock — the 13ci tank mounts at the rear, air travels up through the buffer tube, and your engine receives it without a single external hose in sight. On a CQB or speedsoft build, the difference in handling is significant: no snagging on cover, no line catching your gear, no hardware dangling from the grip.\u003c\/p\u003e\n\n\u003cp\u003eWhat makes the WRAITH X stand out against generic “no-line” solutions is the integrated STORM Category 5 regulator. Most aftermarket lineless setups use basic fixed-output regulators, but the WRAITH X ships with the same Cat5 that Wolverine recommends for all their standalone HPA rigs — adjustable 60–180psi, fast refresh rate, tournament lock. Your engine gets the same consistent, quality-regulated air it would from an external setup, just routed internally.\u003c\/p\u003e\n\n\u003cp\u003eThe CO2 capability is a genuine operational advantage. Rather than needing a filled HPA tank, you can run 12g or 33g CO2 cartridges inside the buffer tube — useful for sites without fill stations, international travel where tanks aren’t practical, or simply as a backup when your HPA tank runs dry mid-game. Switching between HPA and CO2 configurations requires a 2mm hex key to loosen the buffer tube during the conversion.\u003c\/p\u003e\n\n\u003cp\u003eApproximately 1,000 shots from the 13ci\/3000psi tank is a reasonable day’s play for most game formats, but serious milsim or all-day events will want a larger backup tank or a refill option on site.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n  \u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eIncluded regulator\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSTORM Category 5 (integrated, 60–180psi)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eIncluded tank\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e13ci \/ 3000psi HPA tank\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eShot count (13ci HPA)\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e~1,000 shots per fill\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCO2 capability\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e12g or 33g CO2 cartridges (concealed in buffer tube)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAirline type\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eInternal — no external grip line\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBuffer tube thread\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMilspec AR-15 compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHPA ↔ CO2 conversion tool\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e2mm hex key (included)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHigh-quality metal\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWolverine MTW (all variants)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cdiv style=\"background:#1B3A6B;color:#fff;padding:12px 16px;border-radius:6px;margin:18px 0 0;font-size:13px;\"\u003e\n  \u003cstrong style=\"color:#fff;\"\u003e🔧 Titan Forge Airsoft tip:\u003c\/strong\u003e The WRAITH X is the upgrade we see most often on CQB and speedsoft MTW builds.

Once set, they stay until you change them. No phone, no app, no dependencies.\u003c\/p\u003e\n\n\u003cp\u003eROF runs from 10 to 33 RPS across eight presets — you step up through three-round bursts until you reach the desired speed, then stop. Dwell uses a similar method: you hold the trigger and fire once per second, stepping through presets until you notice a drop in FPS, then double-tap to step back up one preset to the optimal setting.

The Maxx M4W is a different class of precision entirely. Where the stock unit is polymer and designed to be adequate at scale, the M4W is CNC machined from aluminium 6061 to the tight tolerances that are only possible through that manufacturing process. The result is a hop-up that holds its adjustment position more consistently, seals to the nozzle and barrel more accurately, and doesn’t flex under the pressure of repeated cycling the way polymer eventually does.\u003c\/p\u003e\n\n\u003cp\u003eThe improvement in BB alignment is the core functional advantage. Three separate anti-wobble systems work together in the M4W: an interchangeable inlet adaptor (OD 11mm) that centres the chamber precisely on the 11mm inner bore of the HPA engine nozzle outlet, eliminating lateral play between the nozzle and hop; CNC brass side wings that slide into the outer barrel slots for positive barrel alignment; and a CNC Delrin locking C-clip that holds the inner barrel tight without movement. Additionally, three compression springs (at the top, bottom, and centre of the housing) ensure the complete unit is exactly centred, straight, and airtight in the receiver.\u003c\/p\u003e\n\n\u003cp\u003eFor hop rubber compatibility, the M4W has been specifically designed with a re-engineered hop lever and 4mm bucking nubs that work correctly with R-Hop, Flat-Hop, and Standard-Hop rubbers — without FPS loss or the BB dropping before the nozzle seals (a common issue with stock hop units when using aftermarket buckings). Optional 6mm nubs are available separately for players who prefer them.\u003c\/p\u003e\n\n\u003cp\u003eThe dual UV LED tracer module is built directly into the chamber body.

It is the single upgrade that most transforms the feel and handling of an MTW.\u003c\/div\u003e\n\n\u003cp\u003eThe Heretic Labs Tank Grip is the defining component of the Article Series. Every Article — I, II, III, and IV — is built around this grip. Understanding what it does mechanically explains why the Article feels the way it does and why players who upgrade their MTW with one rarely go back.\u003c\/p\u003e\n\n\u003cp\u003eStandard MTW builds route HPA from an external tank through a grip line that enters the bottom of the pistol grip. The Tank Grip eliminates every part of that system. The HPA tank screws directly into the base of the grip at a 15-degree angle optimised for the speedsoft stance — slightly rearward-angled, sitting against your hand naturally. Inside the grip body, the STORM Category 5 regulator handles pressure reduction, with its gauge facing forward so you can read your operating pressure at a glance without removing anything. The battery lives in a dedicated internal pocket accessible without tools. The airline routes internally from grip to engine. There is no external hardware, no line, no grip-end clutter.\u003c\/p\u003e\n\n\u003cp\u003eThe practical result: fill the tank, connect the battery, and shoot. The rifle is completely self-contained. Weight distribution shifts rearward (the tank is the heaviest HPA component and it’s now at the balance point of the gun rather than on your back). Handling becomes more instinctive. In CQB and speedsoft where speed matters, the difference between this and a grip-line setup is immediately noticeable.\u003c\/p\u003e\n\n\u003cp\u003eThe glass-filled nylon construction is the right material choice here: lighter than metal, rigid enough to withstand the tank’s weight and the forces of rapid cycling, and resistant to the kind of knocks a speedsoft grip takes in close quarters.

The first is the QUAKE MTW Recoil Stock: the QUAKE is driven by a dedicated recoil port on the INFERNO XTS engine, and without a flow reducer in place, the combined air demand of the engine (firing) plus the QUAKE (recoil cycling) can push the system beyond safe limits.

Rather than being drilled and lapped like most precision barrels, Lambda barrels are \u003cstrong\u003ecold-hammer forged\u003c\/strong\u003e, the same process used to produce real rifle barrels. The bore is formed by compressing the steel around a mandrel rather than cutting it away, which leaves a denser, smoother, more uniformly round surface.\u003c\/p\u003e\n\u003cp\u003eThe tolerance figure is the one that matters: \u003cstrong\u003e1 micron\u003c\/strong\u003e, or 1\/1000th of a millimetre, held along the length of the bore. Most precision barrels quote their diameter but not their consistency, and it is consistency that decides whether every BB leaves the muzzle the same way. Each barrel is finished by hand and given a precision crown at the muzzle, which is where the BB finally separates from the barrel and where any burr or irregularity translates straight into a flyer.\u003c\/p\u003e\n\u003cp\u003eBarrel choice sits downstream of hop-up in the accuracy chain, and it is worth being honest about that: a precision barrel will not rescue a poor hop unit or a worn bucking. What it does is remove the barrel as a variable once the rest is sorted.

It’s not just an aesthetic difference from the stock MTW trigger; the mechanism is fundamentally different. Now available as a standalone upgrade for any MTW or Article platform.\u003c\/div\u003e\n\n\u003cp\u003eThe stock MTW trigger is a functional component that does its job, but it’s not optimised for fast, consistent fire. The Heretic Labs Speed Trigger addresses this at the mechanical level rather than in software. Instead of the standard pivot-and-contact design, the Speed Trigger uses a Delrin bearing (a low-friction polymer composite) at the trigger pivot point. The bearing allows the trigger to rotate on its axis with significantly less friction and more consistent action across the travel than a simple pin-in-hole pivot.\u003c\/p\u003e\n\n\u003cp\u003eThe three-axis adjustability is where experienced players will spend their time. Pre-travel (the distance the trigger moves before registering a shot), post-travel (how far it travels after firing), and trigger switch contact position are all independently adjustable via M3x8 set screws. This lets you dial in a trigger that feels natural for your shooting style rather than adapting to what the gun provides. Competition players typically set near-zero pre-travel for maximum responsiveness; field players may prefer slightly more pre-travel to avoid accidental actuation. Post-travel adjustment means the trigger resets at exactly the position you want, reducing follow-up shot time.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in multiple colour finishes.

If the gearbox is not axially aligned, the nozzle wanders, the hop seals inconsistently, and you chase FPS spread you cannot fix with pressure. The PULSAR D solves that with a second solenoid and a closed-bolt cycle, driving the nozzle positively in both directions instead of relying on a spring and the build quality around it.\u003c\/p\u003e\n\u003cp\u003eThe result is an engine that GATE describe as far less sensitive to replica and assembly quality — zero nozzle wobble, no mid-cap syndrome, and a stable trajectory in full auto rather than just in semi. It holds FPS on auto right up to its 40 RPS ceiling with no drop relative to semi, which is not something most engines can claim.\u003c\/p\u003e\n\u003cp\u003eIt is also the more efficient of the two: roughly 0.7 PSI per shot from a 48ci bottle at 90 PSI, against 1 PSI for the PULSAR S. Velocity spans 250 to 650 FPS, so the same engine covers a CQB build and a DMR. Automatic cycle synchronisation handles the calibration that used to mean firing thousands of rounds to find a stable setting.\u003c\/p\u003e\n\u003cp\u003eA multifunctional port lets you add a bolt-catch button, a magazine sensor, a tracer in the hop-up chamber or an electric magazine feed.

This is one of the core reasons MTW accuracy is as consistent as it is — the engine, hop-up, and barrel are held in perfect alignment by the receiver itself, not by shimming or adjustment.\u003c\/p\u003e\n\n\u003cp\u003eThis kit includes the upper receiver body and the Gen 3 M4 feed tube (MTW-M-327). The feed tube is the component that routes BBs from the magazine into the hop-up chamber — three generations exist, and this is the current standard. Gen 3 feed tubes are compatible with most aftermarket barrels and hop-ups including the Maxx M4W chamber. Gen 1 feed tubes (pre-October 2021 Billet Series) are not compatible with these aftermarket upgrade barrels.\u003c\/p\u003e\n\n\u003cp\u003eGenuine Wolverine Airsoft part (MTW-A-247-SKU).

It replaces the basic trigger board supplied with a stock INFERNO Gen 2 or INFERNO XTS V2 AEG kit and brings the same smart-platform experience to a converted M4 that the MTW owners already enjoy — phone-app tuning, profile saving, and integrated chrono monitoring all happen wirelessly from your pocket.\u003c\/p\u003e\n\u003cp\u003ePair the BLINC with a Bluetooth Acetech chronograph (Bifrost BT, Lighter BT, or AC6000 BT) and the patent-pending auto-tune algorithm dials in your dwell automatically. Without the chrono pairing you can still set ROF anywhere from 1 to 50 RPS per selector position, configure burst lengths from 2 to 10 rounds, set up DMR or binary fire modes, and switch between saved profiles for different sites and energy limits.\u003c\/p\u003e\n\u003cp\u003eChoose between two firmware versions at checkout. Full Auto Capable gives you the complete fire-mode menu including full-auto and binary. Semi Only is locked to semi-automatic regardless of selector position — useful for sites that enforce semi-only rules, for DMR builds, or for tournament play where a hardware-level lock is required. Both versions are identical hardware; the firmware lock is the only difference.\u003c\/p\u003e\n\u003cp\u003ePractical features matter as much as the headline ones. Full-time sleep mode preserves LiPo voltage between games. Short-detection protects the board if a wire pinches in a gearbox shell. The optical selector switch eliminates the wear point of older mechanical selector boards. And firmware updates arrive over Bluetooth, so you never need to crack the gun open to stay current.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePlatform\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eV2 Gearbox AEG (M4 \/ AR-15 style)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBluetooth standard\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBluetooth Low Energy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eApp\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWolverine Airsoft BLINC (iOS \u0026amp; Android)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFire mode options\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSemi, 2–10 round bursts, full-auto, DMR, binary\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFire mode (Semi Only)\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSemi only — firmware locked\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eROF range\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e1–50 RPS, per fire mode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eDwell tuning\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eManual or Auto-Tune (with compatible Acetech BT device)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eChronograph integration\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eLive FPS \/ Joules \/ MPS readout when paired with Acetech BT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBattery monitoring\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eLiPo voltage display on app home screen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eProtections\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eShort detection, full-time sleep mode, digital tournament lock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFirmware updates\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eOver the air via Bluetooth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCertifications\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFCC, IC, TELEC certified for UK, Europe, USA, Canada, Japan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#1B3A6B;color:#fff;padding:12px 16px;border-radius:6px;margin:18px 0 0;font-size:13px;\"\u003e\n\u003cstrong style=\"color:#fff;\"\u003e💡 Titan Forge Airsoft tip:\u003c\/strong\u003e Replacing a Spartan or Gen 1 Premium board with a BLINC unlocks app-based tuning without changing your engine — install the BLINC, pair the app, and you're tuning dwell and ROF without a screwdriver.

Inside the box: the INFERNO XTS engine itself (extended stroke design, redesigned stainless steel nozzle, one-piece Delrin baffle), a BLINC Bluetooth FCU and trigger board, the solenoid, integrated filtered line, and the wiring harness needed for a V2 install. It drops into the same gearbox shell that previously housed your gears, piston and spring — no permanent modifications to the rifle.\u003c\/p\u003e\n\u003cp\u003eThe XTS is the successor to the INFERNO Gen 2, which has been the benchmark drop-in HPA engine for nearly a decade. What's new is the extended stroke system: greater separation between BB loading and firing movements, a redesigned valve housing for more forgiving dwell tuning, and a stainless steel nozzle with additional mass that helps the BB chamber consistently shot after shot. The result on the chrono is tighter shot-to-shot variation; on the field it's tighter groupings at the same FPS.\u003c\/p\u003e\n\u003cp\u003eThe XTS is also genuinely more tunable than the Gen 2. Three levels of optional flow reducers let you tune for low-energy site limits (the UK 1J cap is well within range) without sacrificing the consistency you get at higher pressures. Operating pressure runs 60-160 PSI with a 30 PSI minimum, so the engine still functions cleanly when a tank is running down between fills.\u003c\/p\u003e\n\u003cp\u003eThe BLINC FCU bundled in the kit is the same board sold separately for retrofit installs. You get the full app-based experience out of the box: assign any fire mode to any selector position, set ROF per mode from 1 to 50 RPS, pair an Acetech BT chronograph for auto-tune dwell, save profiles for different sites or energy limits, and update firmware over the air. For V2 AEG owners building HPA from scratch rather than upgrading an existing INFERNO, this kit is the path of least resistance.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eEngine\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eINFERNO XTS — extended stroke hybrid poppet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePlatform\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eV2 Gearbox AEG (M4 \/ AR-15 style)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eOperating pressure\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e60–160 PSI (30 PSI minimum)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eOutput energy\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e1–3 Joule, build dependent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRate of fire\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e5–35 RPS adjustable via BLINC app\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBattery input\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eJST 6–8V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAir efficiency\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eApprox. 3,120–4,160 shots per 48ci \/ 3000psi tank at 1.5J on 10\" inner barrel, ~90 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eNozzle\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRedesigned stainless steel — increased mass for consistent chambering\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBaffle\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eOne-piece Delrin — reduced friction, simplified servicing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFlow reducers\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eThree levels supplied for low-energy tuning\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFCU included\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBLINC Bluetooth FCU — full app control, Acetech BT chrono pairing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAirline\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eIntegrated filtered line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eElectronics compatibility\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAll Wolverine Airsoft electronics ecosystems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#fff8dc;border-left:4px solid #f4b400;padding:10px 14px;border-radius:0 6px 6px 0;font-size:13px;margin:14px 0;\"\u003e⚠ \u003cstrong\u003eConfirm your gearbox first:\u003c\/strong\u003e this kit is for standard V2 gearboxes (M4 \/ AR-15 style AEGs — G\u0026amp;G, KRYTAC, Specna Arms, Tokyo Marui, VFC, Cyma, Ares, and similar).

They are excellent, and they are also the parts most likely to stop you playing — a flat micro-pack, a chafed wire, water where it should not be.

A \u003cstrong\u003e3-axis XYZ alignment system\u003c\/strong\u003e lets you micro-adjust the fit to your particular receiver — which is what makes a mechanical engine behave consistently across guns that are never quite identical.\u003c\/p\u003e\n\u003cp\u003eMechanical does not mean fixed, either.

STORM Category 5 regulator integrated into a stock that houses a 13\/3000 or similar 2-inch HPA tank. No external line, no back-rig, no compromise.\u003c\/div\u003e\n\u003cp\u003eMost HPA setups run a tank on a back-rig with a line to the rifle's grip. That works but it limits movement, snags on cover, and looks nothing like the real-steel rifle the MTW is modelled on. The WRAITH X solves all three problems by integrating the tank into the stock itself: a 13ci or other 2-inch HPA tank slots into the WRAITH X tank stock, screws into the STORM Category 5 regulator at the back of the rifle, and runs the engine through a short internal feed. No line, no back-rig, no harness — just a self-contained HPA MTW that handles like an AEG.\u003c\/p\u003e\n\u003cp\u003eThe STORM Category 5 regulator is Wolverine's flagship. Wide pressure range and high flow rate support everything from low-pressure high-ROF SMG builds up to high-pressure sniper setups in the same hardware. For MTW owners running an INFERNO Gen 2 or XTS this gives you headroom to tune for any UK site, any energy limit, any role — sub-1J CQB through DMR to long-range marksman builds — without changing regulators.\u003c\/p\u003e\n\u003cp\u003eConstruction is the same Wolverine-grade machined aluminium that the MTW platform itself is built from. The tank stock attaches to the MTW receiver where a standard buffer tube would screw in, so installation takes a couple of minutes and a single hex key. Tank changes are fast: depressurise the regulator, unscrew the tank from the rear, swap in a fresh fill, screw back in. No tools needed mid-game.\u003c\/p\u003e\n\u003cp\u003ePractical caveats. The 13\/3000 PSI tank delivers around 1,000 shots per fill at typical UK energy levels, which is good for a half-day's skirmish but won't cover a full game day on high-volume use — budget for a spare tank if you're playing tournaments or full milsim weekends. The kit ships with the regulator and the tank stock but NOT a tank — you'll need to source a compatible 13\/3000 or other 2-inch tank separately.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eIncludes\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWRAITH X STORM Category 5 regulator + WRAITH X tank stock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePlatform\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWolverine MTW (all variants — M4, M9, .308, MK18, AK-105 etc.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eTank compatibility\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e13\/3000 PSI HPA tank or other 2″ diameter tank\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRegulator\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSTORM Category 5 — wide pressure \/ high flow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eApprox. shot count\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e~1,000 shots per 13\/3000 tank fill (engine and tune dependent)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eInstallation\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eScrews to MTW receiver in place of standard buffer tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eLine requirement\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eNone — lineless, self-contained design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCNC machined aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRequired separately\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e13\/3000 PSI HPA tank (or alternative 2″ tank) — NOT included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#fff8dc;border-left:4px solid #f4b400;padding:10px 14px;border-radius:0 6px 6px 0;font-size:13px;margin:14px 0;\"\u003e⚠ \u003cstrong\u003eTank not included:\u003c\/strong\u003e the kit ships with the regulator and stock.
