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

The KNS Precision Gen ST Non-Rotating Trigger/Hammer Pin Kit is a premium stainless steel upgrade for mil-spec AR-15/M16 lower receivers using .154 inch diameter trigger and hammer pin holes. These anti-rotation pins are engineered to eliminate the common problem of trigger and hammer pins walking or rotating out under fire, an issue well documented on 9mm AR-15s, full-auto M4/M16 platforms, and suppressed rifles chambered in .223 and 7.62mm.

Manufactured from stainless steel with a black finish, the Gen ST pins are the strongest design KNS Precision produces, engineered to withstand the high-impact demands of full and semi-auto fire. The low-profile head and flush 0.095 inch side plate keep the assembly snag-free against the lower receiver. Each kit ships complete with an installation guide tool and two Torx wrenches for straightforward installation on any standard mil-spec AR-15 lower.
