CNC Hop-up Chamber M4G (AEG → VSR) – Black

CNC hop-up chamber MAXX Model M4G for AEG and HPA M4 / M16

MAXX Model M4G is a hybrid upgrade chamber combining the advantages of AEG and GBB / VSR systems. It is designed for GBB / VSR buckings and matching GBB inner barrels, providing better air seal, improved accuracy and more stable trajectory, as these components are originally designed for sniper platforms where precision is critical. The precise CNC machining ensures a perfect fit without play, while the rotary TDC adjustment ring allows fine tuning of the hop-up. Thanks to the replaceable pressure segment and optimized arm, the chamber delivers even pressure on the bucking. The design also includes a BB latching system that prevents BBs from falling out when the magazine is removed. Precise alignment is ensured by the inlet adapter and brass guiding wings, while the Delrin C-clip securely locks the inner barrel in place. As a useful upgrade, we also recommend the EPeS illumination module, which turns the side transparent covers into a tracer unit for TRACER BBs.
