BOLT CATCH SPRING - AR15

Restore crisp movement and reliable lockback to your bolt catch assembly with the Always Armed AR-15 Bolt Catch Spring. Proudly Made in the USA, this essential small component delivers the precise outward tension needed to keep your bolt release flush against the lower receiver until the magazine follower triggers a lockback on the last round.

Precision-wound from high-tensile spring steel to exact mil-spec standards, this spring resists memory loss and deformation over thousands of cycles. It prevents the bolt catch from rattling loose or prematurely engaging the bolt carrier under heavy recoil, ensuring consistent lockup and smooth manual bolt release operation.

Designed for universal compatibility across standard AR-15 and .223/5.56 lower receivers, it seats cleanly inside the lower receiver bolt catch plunge well. Whether you are assembling a custom lower parts kit, performing routine bench maintenance, or replacing lost lower hardware, this spring delivers factory-reliable fitment and long-term durability.
