KNS Precision Gen ST Non-Rotating .154 Trigger/Hammer Pin Kit AR-15/M16 FDE

The KNS Precision Gen ST Non-Rotating Trigger and Hammer Pin Kit is the original anti-walk pin solution engineered for mil-spec AR-15 and M16 lower receivers. Designed to eliminate the common problem of trigger and hammer pins drifting or walking out of the lower under fire, this Gen ST (standard generation) kit features precision-machined .154-inch diameter pins that lock firmly in place via the proven non-rotating geometry.

Each pin is machined from stainless steel for lasting corrosion resistance and the durability demanded by high-round-count shooters. This version is finished in Flat Dark Earth (FDE), giving your lower a low-visibility tactical appearance that pairs well with modern rifle builds.

The Gen ST kit installs as a direct-fit replacement for the factory trigger and hammer pins with no permanent modifications to the lower required. Simply remove the standard pins and drop in the KNS non-rotating pins - the unique geometry holds them securely in position through rapid magazine changes and rough field handling.

Manufactured by KNS Precision, a specialist in precision AR-15 components, the Gen ST pin kit has earned a reputation as a trusted upgrade among recreational shooters, competitors, and military end users. It fits AR-15, M16, and M4 platform rifles and pistols built on the standard mil-spec AR-15 lower receiver pattern.
