The MGW CNC Aluminium Hopup Chamber is designed to allow the use of gas blowback/VSR type buckings and inner barrels on the Wolverine Airsoft MTW Milspec, Forged, Billet and MTW-9 series.

The MGW is built with an aluminium Rotary Dial Knob for fine hopup adjustments, the precision Hopup Lever and 4mm Bucking Nubs (6mm Bucking Nubs are optional) to perform best with R-Hop and Standard-Hop to keep the BB shooting accurately and consistently on every single shot.

The MGW unit is designed to accept the HPA MTW Engine M4 nozzle length, and fully compatible with most aftermarket soft and hard rubber buckings without losing FPS or dropping BBs during use.

It is equipped with a self-centering inlet O-ring to ensure the hopup unit is inserted exactly in the center of the 11mm to 11.5mm inner bore HPA Engine nozzle outlet without wobbling.

Removable CNC Brass Side Wings slide smoothly into the outer barrel slots, and also included is an advanced CNC Delrin Locking C-Clip to hold the inner barrel tightly in place without wobbling and twisting.

***Test results: FPS might be increased from 10FPS to 30FPS over the stock setup. Please check your FPS!
