The MTW (Modular Training Weapon) is Wolverine's HPA M4 platform. Instead of a gearbox, it runs an electropneumatic INFERNO engine fed by high-pressure air, which gives near-instant trigger response, excellent shot-to-shot consistency and easy tuning. It keeps a realistic M4 layout, feeds from standard M4/STANAG AEG magazines, and is designed so the engine drops out for maintenance in minutes. Every MTW shares that core — what changes between models is the receiver, the engine tune, the electronics and the format.
Billet vs Forged — the two receiver families
This is the first fork in the range, and it is about how the receiver is made rather than how the rifle shoots.
| MTW Billet | MTW Forged | |
|---|---|---|
| Receiver | CNC-machined from billet aluminium by Wolverine | Made from genuine AR-15 forgings |
| Look & feel | Clean, modern, slightly oversized billet lines | True mil-profile — indistinguishable from a real AR |
| Best for | The core range — skirmishers and speedsoft players who want performance and value | Milsim and collectors who want maximum authenticity |
| Price tier | Entry to mid | Flagship |
| Examples | Billet Standard 10", Billet Tactical 14" | Forged Tactical 10", DD MK18 |
If you are buying your first MTW to skirmish with, Billet is almost always the right call — it shoots identically to a Forged rifle for a good deal less. Forged earns its premium if authenticity matters to you or you run a milsim impression.
The engine: INFERNO vs INFERNO XTS
Every MTW runs an INFERNO engine. The standard INFERNO is superb and needs nothing added for most players. The INFERNO XTS is the upgraded tune, and it is what the “X” in a model name refers to.
- Standard INFERNO — proven, consistent, quiet, and fully tunable. Fitted to the bulk of the range.
- INFERNO XTS — an extended-stroke design with a stainless nozzle and Delrin baffle for tighter shot groupings and more forgiving dwell tuning. It also adds a QUAKE port, so you can bolt on the QUAKE recoil kit later.
For most skirmishers the standard INFERNO is all you will ever need. Choose an XTS build if you want the tightest consistency out of the box or you know you will want QUAKE recoil down the line.
The electronics: Spartan vs BLINC
The fire-control unit (FCU) sets your rate of fire, dwell, fire modes and burst. There are two, and the choice comes down to whether you want a phone in the loop.
| Spartan FCU | BLINC Bluetooth FCU | |
|---|---|---|
| Control | Programmed on the gun via trigger sequences | Wireless control from a phone or smartwatch app |
| App needed | No — nothing to download, no phone battery to rely on | Yes — the Wolverine app (iOS/Android and more) |
| Adjust on the field | Yes, but menu-driven on the trigger | Instant — change RPS/dwell/mode in the app between games |
| Best for | Players who want simplicity and no phone dependency | Players who tune often or move between sites with different RPS caps |
| Marked as | Most Gen3 builds | The “B” in a model name (e.g. AK-105 XB) |
You can buy a Spartan control board separately too, so the FCU is not a permanent decision — but it is worth choosing deliberately up front.
Decoding the names: Gen3, X, XB, Standard, Tactical, Unleashed
- Gen3 — the current generation of the Billet receiver and internals. If you see Gen3, it is the latest core spec.
- X — fitted with the INFERNO XTS engine.
- XB — INFERNO XTS engine and BLINC Bluetooth FCU (the two headline upgrades together).
- Standard vs Tactical — furniture and rail level. Standard is the leaner, keener-priced build; Tactical adds a fuller handguard, upgraded grip and a more equipped look.
- Unleashed — a complete, lineless HPA setup in the box: a WRAITH X stock with a built-in regulator and a 13ci tank, so there is no external line or separate tank to buy. The easiest way to get a fully running HPA rifle in one purchase.

Which MTW should I buy?
- Your first MTW / best value: the Billet Standard 10".
- CQB and speedsoft: the Billet Tactical 7" CQB — short, fast and manoeuvrable.
- Zero-faff, everything in the box: the Billet Unleashed — no line, no separate tank.
- Maximum authenticity / milsim: the Forged Tactical or the DD MK18.
- Top-spec, tune-everything build: anything with the XB trim, like the AK-105 XB.
- Marksman / DMR: the MTW-308.
Three upgrades worth planning for
- FRAC kit — moves the air line to the rear of the buffer tube for a cleaner build; the first upgrade most owners fit.
- WRAITH X stock — a lineless stock with a built-in regulator and 13ci tank; roughly 1,000 shots per fill with no external line.
- STORM Category 5 regulator — Wolverine's recommended regulator for any HPA build.

Frequently asked questions
Do all MTWs use the same magazines?
The M4 models all feed from standard M4/STANAG AEG magazines. The MTW-9 uses ASG EVO magazines, the AK-105 uses AK-format AEG magazines, and the MTW-308 uses SR-25-pattern magazines.
Is Billet or Forged better?
Neither shoots better — they share the same engine and internals. Billet is the value choice; Forged is for authenticity and milsim. Most skirmishers are happiest on Billet.
What is the difference between INFERNO and INFERNO XTS?
The XTS is an extended-stroke tune with a stainless nozzle and QUAKE port for tighter groupings and future recoil-kit compatibility. The standard INFERNO is excellent for most players.
Do I need the BLINC Bluetooth FCU?
Only if you like tuning from an app or move between sites with different RPS limits. The Spartan FCU does everything on the gun with no phone required.
What do I need to actually run an MTW?
An HPA tank, a regulator and a line — unless you buy an Unleashed model, which includes a lineless tank-stock setup in the box.
Do I need a licence to buy one?
Yes — every MTW is a realistic imitation firearm, so you need UKARA or another valid defence, which we verify at checkout.
