The KNS Precision Non-Rotating Trigger/Hammer Pin in .1555-inch G2 (KNS Precision part no. NRTHP-1555) replaces a standard AR-15/M16 trigger or hammer pin with what KNS Precision calls the strongest pin it can produce. KNS Precision designed the G2 pin to withstand the high impact loads of full-auto and semi-auto 9mm, .223, and 7.62mm suppressed weapons, conditions that can accelerate wear on a standard rotating pin. The pins themselves are stainless steel, and this black version carries a black nitride treatment for added hardness and corrosion resistance. It is a near-must-have upgrade for M16 owners and works just as well protecting an AR-15.

Frequently Asked Questions

Does this pin fit both trigger and hammer positions? Yes, it is designed as a non-rotating trigger and hammer pin for AR-15/M16-pattern lowers.

Why does a suppressed weapon need a stronger pin? Suppressed and sustained-fire use increases impact loading on the trigger and hammer pins, and KNS designed this pin specifically to hold up under that added stress.
