Sons of Liberty Gun Works Firing Pin Retaining Pin for AR-15
The Sons of Liberty Gun Works Firing Pin Retaining Pin is the factory OEM cotter pin that holds the firing pin inside the bolt of a mil-spec AR-15, M4 or M16 bolt carrier group. It is one of the smallest parts in the rifle and one of the easiest to drop and lose during cleaning or a detailed strip – so keeping a spare or two on hand is always a smart move. Made to SOLGW’s usual quality standards, it drops straight into any standard AR-15 BCG.
