AR-15 Bolt Catch Spring
The AR-15 Bolt Catch Spring is a mil-spec replacement spring for the bolt catch assembly on any standard AR-15, M16, or M4 lower receiver. Wound from hardened spring steel, it delivers the consistent upward tension needed to keep the bolt catch functioning reliably — locking the bolt to the rear on an empty magazine and releasing it cleanly when the paddle is pressed. It drops straight into the bolt catch detent recess of any mil-spec lower with no fitting required. A smart spare to keep on the bench for builders, armorers, and anyone running an AR platform hard.
