Maxx Model CNC Aluminum Hopup Chamber - M4E (Standard M4)

CNC Aluminum Hopup Chamber M4E unit is precisely machined to perform accurately and consistently on Tokyo Marui (includes G&G, KRYTAC, except KWA) Standard M4/M16 AEG series M4 rifles. 

The Hopup Chamber M4E unit is built with an aluminum Rotary Dial Knob for fine hopup adjustments, the precision Hopup Lever and 4mm Bucking Nubs and tensioners (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 M4E unit is designed to accept 21.00mm to 21.25mm nozzle length, and fully compatible with most aftermarket soft and hard rubber buckings without losing FPS or dropping BB during use.

These units work especially well with Maple Leaf buckings
