CMMG AR-15 Bolt Catch Assembly Kit

The CMMG AR-15 Bolt Catch Assembly is a mil-spec replacement bolt catch designed to drop into any standard AR-15 lower receiver. It is also fully compatible with the Magpul BAD Lever for shooters running that accessory on their build.

This bolt catch assembly kit ships complete with every small part needed for installation: the bolt catch, bolt catch spring, roll pin, and plunger. Having the full set on hand eliminates the frustration of hunting down a lost roll pin or spring during a lower build or strip-down.

Manufactured by CMMG to standard mil-spec dimensions, this bolt catch is a reliable choice for a fresh build, a direct replacement for a worn or broken factory unit, or as a bench spare. CMMG part number 55AFF34.
