CTM TAC Hi-Capa HPA M4 Magazine Adapter Kit for GBB Airsoft Pistols

Convert your compatible Hi-Capa pistol for HPA use with the CTM TAC Hi-Capa HPA M4 Magazine Adapter Kit. Designed for speedsoft, competition, and high-performance airsoft builds, the CTM TAC adapter allows your Hi-Capa to operate on an external HPA system while feeding from standard M4 AEG magazines.

The adapter features a lightweight glass-reinforced nylon body, a CNC-machined 6061 aluminum magazine release, steel valve components, and an integrated BB retention system designed to minimize BB loss during magazine changes. It is compatible with popular M4 AEG magazines, including the PTS SpeedQB EPM and similar standard M4 magazines.

IMPORTANT – DONOR HI-CAPA MAGAZINE REQUIRED

This product is an HPA adapter kit and is not a complete, ready-to-use Hi-Capa magazine. Installation requires compatible components from a donor Hi-Capa gas magazine. A Hi-Capa gas magazine is NOT included. Installation and disassembly of a compatible magazine are required.

An HPA tank, regulator, air line, and M4 AEG magazine are also required for a complete HPA setup and are sold separately.
