🧵 Routes HPA internally through the pistol grip — no exposed bend at the engine, no external line snag point. The Amped IGL is purpose-built for each engine's specific fitting format. Select the correct variant for your engine from the options above — fitting geometry and line length differ between engine types. Not compatible with Wolverine MTW series or Tippmann M4.

Standard macro line exits your HPA engine, bends around the receiver wall, and drops down to the pistol grip — that bend is the most snagged, most kinked, and most failure-prone section of a typical HPA rifle's air system. The Amped Integral Grip Line eliminates it. The IGL is designed to clip directly behind the engine's output and route the widebore line internally through the pistol grip, exiting cleanly at the base. The result is a tighter install, a lower snag profile, and better protection of the line at the most vulnerable point.

Each IGL variant uses a fitting matched to its specific engine. This matters — the F2, Fusion Engine, Kythera, and TM Shotgun all use different connection geometry. Select the correct option at checkout. If you're unsure which variant your build needs, call us on 01494 911990 and we can confirm before you order.

The IGL 2.0 variants (F2 IGL 2.0 and TM Shotgun IGL 2.0) introduce a two-stage CNC machined metal quick-disconnect fitting that can be retrofitted with the PolarStar Filtered QD fitting at any time. This matters specifically for PolarStar engine owners: running a filterless line on a PolarStar engine can void the manufacturer warranty. The IGL 2.0's two-stage QD means you can add PolarStar's filtered fitting later without buying a new line, and protects the engine warranty immediately even before the filter is added. All IGL 2.0 variants ship with the two-stage QD as standard.

Installation notes

Fitting the IGL requires enlarging the hole in your rifle's grip plate to accommodate the line — use a 1/2" drill bit to enlarge the grip plate hole, or remove the grip plate entirely. The upper grip motor hole may also require enlarging depending on your specific rifle body. This is a one-time modification. For IGL 2.0 variants on some builds, you may need to unscrew the engine solenoid and thread the IGL in before screwing the solenoid back alongside it due to tight internal clearances. Fusion Engine V3 and M249 installations require additional receiver modification to route the line — the line will not pass through the standard grip bolt hole on these platforms.

🔧 Titan Forge Airsoft tip: If you own a PolarStar F2 or Fusion Engine, the IGL 2.0 variants are worth the small additional cost over the original IGL for the filter-ready QD fitting alone — running a filterless line on a PolarStar engine risks voiding the manufacturer warranty, and the two-stage fitting gives you the option to add the PolarStar Filtered QD at any time without replacing the line. Not sure which variant fits your specific engine? Call us on 01494 911990 — fitting errors on IGLs are entirely avoidable.
