Description

The CMMG Mk4 Firing Pin Retainer Pin is a replacement slide part for AR-15 style rifles. It secures the firing pin within the bolt carrier group, making it a useful component for a new build or for keeping spares on hand.

This pin is made from steel and has a silver finish. It is designed to fit the AR-15 and M16 bolt pattern, so it is intended for use with bolt carrier groups built to that standard.
