The Maxx CNC Aluminium Hopup Chamber M4G is designed to allow the use of gas blowback/VSR type buckings and inner barrels on the Tokyo Marui Standard M4/M16 AEG series.

It comes with an aluminium Rotary Dial Knob for fine hop up adjustments, the precision hop up 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 Hopup Chamber M4G unit is fully compatible with most aftermarket soft and hard rubber buckings without losing FPS or dropping BB during use.

The Hopup Chamber M4G unit is equipped with an interchangeable Inlet Adaptor to ensure the hop up unit is inserted exactly in the center of the inner bore of the AEG Gearbox or HPA nozzle outlet without wobbling.

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

A BB Latching System prevents BBs dropping out after removing the magazine. The Latching Arm can also be manually pressed to release the remaining BBs from inside the hop up chamber.
