The Next-Gen Hi-Capa M4 HPA Adapter is AirTac's premium-tier conversion for the Hi-Capa, SSP, and SSP5 platforms — designed specifically for players who use the Hi-Capa as a competition or primary HPA pistol and want an adapter built to match that use case. The Hi-Capa is the most popular GBB pistol platform in speedsoft globally, and having an adapter that can keep up with intensive competition use was the brief for the Next-Gen programme.
The critical upgrades over standard Hi-Capa adapters: the magazine release and feed tube are both CNC machined rather than moulded. The CNC feed tube maintains tighter dimensional tolerances, which translates to more consistent BB path geometry from magazine to hop-up — under competition conditions where every shot at close range matters, this consistency is worth having. The CNC magazine release handles rapid, repeated magazine changes without developing the play or deformation that moulded polymer releases can show under intensive use.
A single-stack adapter and O-ring are included for compatibility with narrower magwell setups. BB retention is integrated into the adapter to minimise loss on fast magazine changes. Compatible with flared magwells for the fastest possible magazine insertion. US Foster HPA fitting. Fully compatible with TM, WE, and SSP5 Hi-Capa platform bodies.
