This adapter allows you to run HPA on your GHK G5 or M4 variant

Comes pre-fitted with valve, feed lips and gas router - you do not need to use any donor parts. No assembly is required.

The magazine catch area of this adapter is adjustable, and comes with three shims allowing you to adjust nozzle to gas router seal. We test each adapter in a GHK G5 before shipping, and prefit the shim that provides us the best performance.

The gas router for this adapter is made from injection moulded rubber, to the standard GHK spec and dimensions, meaning you can use a factory or aftermarket GHK M4/G5 router should you wish.

We utilise a non GHK valve due to their flawed valve seal design. This has allowed us to build a far more reliable adapter that is capable of high FPS and sustained full auto.

Includes one set of spare feed lips, and magazine catch shims labelled 1 to 3, along with all screws required to fit any of our modular magwell bases.

US Style HPA Fitting as Standard (most common fitting across industry - compatible with all AIRTAC HPA equipment)
