KNS Precision AR15 Firing Pin Retaining Pin – AR-15/M16

The KNS Precision AR-15 Firing Pin Retaining Pin is a direct replacement for the factory pin that secures the firing pin inside the bolt carrier group. This small but critical component prevents firing pin migration during the cycling process. Shooters replace this pin when the original is lost during cleaning, damaged, or as part of a routine BCG maintenance overhaul. KNS Precision manufactures this pin to MIL-SPEC dimensions for reliable function in all AR-15 and M16 bolt carrier groups.

Machined from heat-treated steel with a corrosion-resistant finish, this retaining pin installs in seconds without tools or modification. Simply insert through the bolt carrier cross-hole to capture the firing pin. This is a drop-in component that requires no gunsmithing. Keep spares on hand—losing this pin during field maintenance renders the rifle inoperable until replaced.
