The KNS Precision Gen ST pin kit (brand part number NRTHPGENSTBK) replaces the standard trigger and hammer pins on a mil-spec AR-15 or M16 with KNS’s non-rotating sideplate design. The pins are machined from stainless steel and finished with a black nitride treatment on the sideplates for durability and a clean, low-glare look. This Gen ST version carries the same .154-inch pin diameter as KNS’s other non-rotating kits, giving your receiver a wear-resistant upgrade over standard factory pins.
