PART, MPX, DETENT, GAS VALVE

The MPX Gas Valve Detent is a hardened, precision-made detent pin and spring assembly that holds the gas valve in its selected position, preventing unwanted rotation or drift during firing and transport. Designed for the SIG MPX gas system, this small but critical component ensures consistent gas flow settings and repeatable cycling. Constructed from durable materials to resist wear and corrosion, it’s an essential replacement part for maintenance, repairs, or restoring factory function.
