The KNS Non-Rotating Pin Kit (brand part no. NRTHPMOD2-154-Black) replaces the factory trigger and hammer pins on a mil-spec AR-15/M16 lower with a non-rotating design that reduces wear on the receiver over time. This Gen 2 Mod 2 kit uses .154-inch diameter stainless steel pins, and the black nitride-treated sideplates lock the pins in place so they can’t spin and gradually enlarge the pin holes the way factory pins can. It’s a precision fit for mil-spec AR-15/M16 lowers and a straightforward upgrade for shooters who want to protect their receiver and improve trigger pull consistency over the long term.
