5KU Tokyo Marui Hi Capa GBB Mag Catch Screw M3x5 (Stainless Steel, Type B) - Silver

Routine grip swaps and heavy maintenance cycles on Tokyo Marui-pattern Hi-Capa sidearms often take a heavy toll on factory zinc-alloy hardware, leading to rounded tool interfaces and stripped threads. Engineered to replace failure-prone stock components, the 5KU M3x5 Stainless Steel Mag Catch Screw delivers a hardened, high-strength solution that locks down your magazine release mechanism under intense gas blowback recoil. Precision CNC-machined from stainless steel with a wear-resistant coating, this M3 x 5mm fastener features a Type B low-profile head that seats completely flush inside original and custom lower frames. It offers reliable shear resistance and thread longevity for Tokyo Marui Hi-Capa 5.1, 4.3, and Gold Match models, along with TM-spec clones from WE, AW Custom, and Novritsch, with every package supplying one black M3x5 stainless steel magazine catch screw.
