TPS Arms AR-15 Bolt Catch Assembly - Black

The TPS Arms AR-15 Bolt Catch Assembly is a complete drop-in replacement set for the AR-15 platform that bundles the four critical small parts needed to lock the bolt open after the last round: the bolt catch, buffer, roll pin, and spring. Manufactured from steel with a black finish, the assembly is built to standard AR-15 dimensions for direct installation into any standard lower receiver.

This AR-1032 bolt catch assembly is a practical choice for completing a fresh lower build, replacing a worn or broken factory bolt catch, or refreshing a well-used rifle that has developed play or sticky lock-back. With all four pieces supplied in one package, you have everything required to install the assembly without sourcing each component separately, making it a convenient addition to any AR-15 lower parts kit or a reliable standalone replacement part.
