High-cadence cycling and aggressive short-stroke modifications frequently push factory Tokyo Marui trigger group components past their mechanical limits, leading to sluggish resets and hammer follow. Built specifically to restore crisp, positive reset geometry in hard-running competition and high-pressure green gas builds, the Dr. Black Disconnector Spring Set provides calibrated spring tension directly to the disconnector interface to eliminate reset lag and prevent semi-auto runaway under sustained rapid fire. Precision-formed from high-tensile tempered spring steel with a raw silver finish for extended fatigue resistance, this critical maintenance and tuning component restores a firm upward bias to guarantee clean trigger bar engagement. It serves as an essential upgrade for Action Air (IPSC), Speedsoft, and custom competition builds, seamlessly fitting Tokyo Marui Hi-Capa 5.1, 4.3, 1911 series, and compatible spec aftermarket mid-frames from brands like Airsoft Masterpiece, EDGE, and CowCow.
