High-cycle gas blowback platforms routinely stress and back out substandard mounting hardware under sustained recoil. The 5KU M4x7 Type B screw provides a precise, hardened replacement engineered specifically to anchor micro red dot bases and chassis mounts onto Tokyo Marui-spec Hi-Capa frames. Precision CNC-machined from high-grade stainless steel with a wear-resistant anti-glare black coating, it eliminates the stripping and shearing risks common to factory pot-metal fasteners. Featuring a metric M4 x 7mm thread specification and a Type A low-profile countersunk head profile, it guarantees snag-free optic clearance and reliable retention. This fastener is directly compatible with Tokyo Marui, WE-Tech, AW Custom, 5KU, and standard aftermarket Hi-Capa 4.3 and 5.1 optic mounts requiring M4 threading.
