Ar-15 Bolt Catch Spring

The AR-15 Bolt Catch Spring is a critical internal component designed for the AR-15 platform, ensuring reliable function of the bolt catch mechanism. This spring is essential for shooters who require consistent operation in various shooting scenarios, from training at the range to tactical applications.

Engineered to precise tolerances, this bolt catch spring ensures reliable engagement with the bolt carrier group and magazine follower. Its minimal weight of 0.01 lbs reflects a compact design typical of quality AR-15 internals, which must perform flawlessly under rapid fire and extended shooting sessions.

This replacement spring is vital for maintaining operational readiness, as a worn or degraded spring can compromise the bolt hold-open function on an empty magazine. Law enforcement armorers, military small-arms technicians, and serious recreational shooters will benefit from the durability and reliability of this essential component.
