Frequently Asked Questions

What does ‘M16 cut’ mean on a bolt carrier? An M16-cut carrier has the internal geometry for a full-auto-capable lower’s auto sear to engage; it functions safely in a semi-auto-only AR-15 lower as well.

What does the side-vent design do? It’s a carrier design that vents gas to the side rather than only through the top, which some shooters prefer for gas management.

What finish does this BCG use? It’s finished in chrome on the bolt with a phosphate finish elsewhere, a common mil-spec-style combination.
