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