The KNS Precision Gen 2 non-rotating pin kit (brand part number NRTHP-154) replaces the standard trigger and hammer pins on a mil-spec AR-15 or M16 with laser-marked, non-rotating sideplates so you can identify your rifle’s chambered caliber at a glance. The pins themselves are machined from stainless steel, and special anti-creep retainers keep them from walking during use, protecting your irreplaceable receiver from the wear that loose factory pins can cause over time. This Gen 2 version carries the same black nitride-treated sideplates KNS is known for, sized to a .154-inch pin diameter.
