M4XIMUS HPA Kit | TM Hi-Capa | Tan | CTM TAC

This HPA kit transforms your Hi-Capa pistol into a system that can use AEG M4 magazines. The system works through a direct connection between your HPA line and the modified lower frame, with the M4 magazines serving as the BB source. You use this kit when you need higher magazine capacity during longer skirmishes or when you want to share the same magazines between your M4 and your pistol. The keyword HPA accessories covers exactly what this product offers: a complete conversion kit for High Pressure Air setups.

Technical characteristics

The main body and magazine section are manufactured from reinforced nylon fibre, a material that withstands the forces of HPA systems. The tan colour gives the kit a tactical appearance that suits many replicas. The M4 magazine release button is CNC-milled for precise operation. The frame has stippled grips for grip and contains a window in the trigger guard where you can monitor BB flow. The kit features a BB locking mechanism that prevents BBs from falling out of the system during magazine changes.

Compatibility and application

This HPA kit is designed for Hi-Capa pistols and works with slides and frames from all brands, including Tokyo Marui originals. The system supports AEG M4 magazines from brands such as PTS, Poseidon, Guarder, G&G and many others. Installation requires basic knowledge of HPA systems and Hi-Capa pistols. The kit fits within both speedsoft and milsim builds where magazine capacity and cross-platform compatibility are desired.
