The J P Enterprises Firing Pin Retaining Pin .308 is a purpose-built cotter-style pin engineered for large-frame AR .308 and AR-10 class bolt carriers. Designed to replace the standard split-pin retainer, it offers more secure firing pin retention and improved longevity, especially in rifles built on the DPMS LR-308 pattern or JP bolt carriers.

This small but critical component helps keep your rifle running smoothly by locking the firing pin in place during every cycle. It is ideal for shooters who regularly maintain their bolt carrier groups, as well as builders who want a dependable wear item on hand for their .308 AR platforms. Backed by JP Enterprises’ reputation for precision parts and thoughtful engineering, this retaining pin is a straightforward upgrade over conventional split-pin designs.
