An AR-15 bolt catch detent is a small, spring-loaded pin that secures the bolt catch in place and allows it to function correctly. It works with the AR-15 lower receiver, bolt catch, and bolt catch spring. The detent ensures the bolt catch can reliably engage and release the bolt during locking and releasing operations. It is an essential part of the lower receiver assembly and is compatible with all standard AR-15 builds and lower parts kits.
