MAXX Model M4Gi is a hybrid upgrade chamber combining the advantages of AEG and GBB / VSR. It is designed for GBB / VSR buckings and matching GBB inner barrels, ensuring better air seal, higher accuracy and more stable trajectory, as these components are originally designed for sniper platforms where precision is essential. The chamber is specifically designed for ICS AEG rifles (SSS, CXP, CS4, EBB and older models), providing perfect compatibility and fit. Precise CNC machining ensures tight tolerances, while the rotary TDC adjustment ring allows fine tuning of hop-up pressure. Thanks to the replaceable pressure segment and optimized arm, the chamber delivers even pressure on the bucking. The design also features a BB latching system with lever that prevents BBs from falling out and allows quick manual release. Precise alignment is ensured by the inlet adapter and brass guiding wings, while the Delrin C-clip locks the inner barrel securely in place. As a useful upgrade, we also recommend the EPeS illumination module, which converts the side transparent covers into a tracer unit for TRACER BBs.
