Reliable replacement firing pin for AR-15 platforms chambered in .223 Remington, 5.56 NATO, or .300 Blackout. Silver finish.
Fits: AR-15
A critical component in any AR-15's bolt carrier group, the firing pin is responsible for reliably striking the primer and initiating ignition. This silver-finished pin from CMMG is engineered to exacting standards for consistent performance across all common AR-15 calibers.
Firing pins wear with use and can eventually fail to reliably ignite primers. Whether you're replacing a worn component or building a new rifle, having a quality firing pin ensures your rifle will fire when you need it to. CMMG has been manufacturing AR-platform components since 2002, bringing decades of expertise to every part they produce.
This straightforward replacement part is essential for any AR-15 owner who maintains their own rifle or builds from components.
