CMMG AR-15 Bolt Assembly 5.56x45mm NATO

The CMMG AR-15 Bolt Assembly is a replacement bolt for AR-15 bolt carrier groups, supplied as a complete assembly with its extractor and ejector installed. It is intended for use in the 5.56x45mm NATO and .223 Remington chamberings.

The bolt is finished in matte black and manufactured from 9310 steel. It is designed to fit a mil-spec AR-15 bolt carrier, so it can be dropped into a compatible carrier without modification.

Because it is a complete assembly, the extractor and ejector come pre-installed, which simplifies replacement or rebuilding of an AR-15 bolt carrier group.
