CNC Hop-up Chamber M4P PRO (HPA PolarStar) – Blue

CNC hop-up chamber Maxx Model M4P PRO for HPA M4 / M16 (PolarStar)

Maxx Model M4P PRO hop-up chamber is among the absolute top on the market and is designed for demanding users. The chamber is machined from a single piece of aerospace-grade aluminum using CNC, ensuring precise tolerances and perfect alignment with the body and HPA system. The rotary adjustment wheel allows fine hop-up tuning, while the redesigned TDC pressure arm ensures even pressure on the bucking, the M4P version even includes 5 different aluminum nubs. The chamber is fully compatible with R-Hop and standard AEG hop-up buckings and is dimensionally optimized for use with all PolarStar HPA systems. Thanks to the BB latching system with lever, BBs do not fall out after removing the magazine and can be quickly released by pressing the lever. Precise nozzle alignment is ensured by a replaceable inlet adapter and brass guiding surfaces that eliminate misalignment and improve barrel stability. As a useful upgrade, we also recommend the EPeS illumination module, which transforms the side transparent covers into a tracer unit for TRACER BBs.
