Brownells BRN AR-15 Mil-Spec Bolt Catch

The Brownells BRN AR-15 Mil-Spec Bolt Catch is a direct replacement part designed to meet military specification standards for AR-15 platform rifles. This bolt catch holds the bolt carrier group open on the last round fired and allows the shooter to release the bolt with a press of the paddle. Built to mil-spec dimensions for reliable fit and function in standard AR-15 lower receivers.
