The Dr. Black 145% Nozzle Spring for the Tokyo Marui Hi-Capa GBB is a direct drop-in upgrade built for high-speed custom builds. Its 145% tension forces the loading nozzle firmly back into battery, preventing nozzle stick, feeding failures, and double feeds during rapid fire. Made from high-strength spring steel with a sleek silver finish, it provides reliable chambering, a solid gas seal, and excellent fatigue resistance. It fits Tokyo Marui Hi-Capa 5.1 and 4.3 GBB pistols and similar 1911 GBB models, with zero length variance for standard TM blowback housings and no modification needed. It adds zero grams of weight, keeping cycling efficiency at maximum. One spring is included. Suitable for Tokyo Marui Hi-Capa GBB airsoft pistols.
