When building a high-cadence gas blowback pistol, the factory return springs often struggle to keep up with lightweight custom slides and high-pressure gas systems. This lag causes sluggish nozzle return and severe feeding issues. The Dr. Black Tokyo Marui Hi Capa 145 percent Nozzle Spring solves this problem by eliminating nozzle stick and preventing double feeds during rapid fire. It does this by forcing the loading nozzle back into battery with serious authority.
By bumping the return tension up to 145 percent, this silver colored spring ensures reliable chambering and a rock-solid gas seal. It is a necessary upgrade for competitive Action Air participants or CQB players who need their gear to cycle flawlessly under heavy pressure. Crafted from high-tensile spring steel, it offers excellent fatigue resistance for long-lasting performance.
This Dr. Black component is fully compatible with Tokyo Marui Hi Capa 5.1 and 4.3 models, as well as similar 1911 gas blowback pistols. The spring is engineered with zero millimeter length variance, meaning it drops perfectly into standard TM specification blowback housings without any need for modifications. Furthermore, it adds zero grams of weight to your build, maintaining absolute maximum cycling efficiency. Each package includes exactly one 145 percent nozzle spring ready for installation.
