KNS Perma Firing Pin Retaining Pin
The firing pin retaining pin is a small but critical component in your AR-15's bolt carrier assembly. KNS Precision's Perma retaining pin replaces the standard cotter pin that secures your firing pin in place.
Why It Matters
The original Stoner design relied on a simple cotter pin to keep the firing pin from backing out of the bolt carrier. Over time and with heavy use, standard cotter pins can work loose or break, potentially causing reliability issues. KNS engineered this replacement to provide a more permanent solution.
