Let’s Talk About KNS Precision PERMA Firing Pin Retaining Pin
The KNS Precision PERMA Firing Pin Retaining Pin offers a simple yet effective upgrade to the standard AR-15/M16 bolt carrier group. Designed by KNS Precision, this drop-in replacement for the often-fiddly cotter pin promises easier installation and enhanced durability. It’s a seemingly small component, but one that can drastically improve the maintenance experience and potentially boost reliability.
I’ve always been frustrated with the standard cotter pin. Getting it lined up properly during reassembly after cleaning is a constant source of annoyance. I was looking for a more user-friendly and robust solution to this common AR-15 maintenance hurdle.
The KNS Precision PERMA Firing Pin Retaining Pin arrived in a simple, no-frills package. Initial inspection revealed a cleanly machined, black-finished part. The weight felt negligibly different from the standard cotter pin, but the one-piece design immediately impressed me.
Compared to the standard cotter pin and even some enhanced roll pin options, the KNS Precision offering seemed significantly easier to manipulate. Other solutions are improved cotter pins, or a two piece screw, but they add complexity. This one piece design grabbed my attention and seemed like a better design. My first impression was one of cautious optimism; this could be a game-changer for quick and easy BCG maintenance.
