CTM Hi-Capa M4XIMUS HPA Adaptor Kit

This is the Hi-Capa version of the M4XIMUS conversion: a full nylon-fibre frame and magazine that take a Tokyo Marui Hi-Capa onto air and let it feed from any brand of AEG M4 magazine. You trade the gas magazine's modest capacity for a rifle stick's worth of rounds, and you pick up the flat, weather-proof consistency that running regulated air gives over green gas.

CTM built it to be forgiving about what it bolts to. It accepts uppers and frames from any brand, the original factory parts included, so you are not forced onto a particular slide or barrel, and it is cut for the Tokyo Marui Hi-Capa 5.1 and 4.3.

The detail work is where it earns its keep. The M4 magazine connector uses a BB-locking design that holds rounds inside the kit when you pull the magazine, so you are not scattering BBs across the floor on every change. The magazine release is CNC-machined for a clean, repeatable drop, an open window in the trigger guard lets you watch the BBs track along the feed path, and the polka-dot grip panels give a genuinely positive hold.

At a manufacturer-stated 200 g, it keeps the gun light enough to run comfortably while you manage the air line.
