Cmmg Ar15 Roll Pin For Bolt Catch

The CMMG AR-15 roll pin for bolt catch is a straightforward replacement part for builders and armerers maintaining AR-15 platforms. This is the small but essential pin that holds your bolt catch assembly in place—one of those parts you don't think about until you need it. Whether you're assembling an upper receiver, upgrading an existing rifle, or just keeping spares in your toolkit, having the correct OEM-spec roll pin on hand beats a trip to source one mid-build.

CMMG has manufactured AR components since 2002, and this roll pin meets the standard dimensions for AR-15 bolt catch assemblies. It's a consumable item that sees occasional wear during disassembly and maintenance, so keeping a few extras makes sense if you regularly work on your rifles.

This is a no-frills, no-questions component—grab it if you know exactly what you need, or reference your receiver schematic to confirm compatibility with your build. It's the kind of part that disappears into your rifle and does its job without any drama.
