CMMG Zeroed AR-15 Bolt Catch Kit - Black Steel

Upgrade the controls of your AR-15 lower with the CMMG Zeroed Bolt Catch Kit (part number 55AFF19). Part of CMMG's popular Zeroed line of drop-in accessories, this extended bolt catch is machined from steel and finished in a durable black nitride coating that matches the rest of the Zeroed component family.

The Zeroed bolt catch features dual oversized extended paddles with a tactile machined surface, giving the shooter a positive, oversized engagement point for rapid bolt release without breaking the firing grip. The all-steel construction keeps the part solidly mil-spec in feel and function, and the included hardware allows for a straightforward drop-in installation on mil-spec AR-15 lower receivers.

Designed and produced by CMMG, the 55AFF19 kit ships as a ready-to-install replacement for the factory AR-15 bolt catch and weighs in at roughly 0.46 oz. Whether you're building out a new lower or refreshing an existing rifle, the Zeroed bolt catch delivers the upgraded ergonomics and reliable steel construction that have made the CMMG Zeroed line a go-to choice for AR builders.
