FAQ

Do I need a special bolt and magazines for 6.5 Grendel?

Yes. 6.5 Grendel needs a Grendel-specific bolt carrier group with the larger Grendel bolt face and 6.5 Grendel magazines. A standard 5.56 BCG and magazines will not work, but your mil-spec AR-15 lower will.

Is a bolt carrier group included?

No. Add a 6.5 Grendel BCG; it is available as an add-on on this page.

What twist rate and chamber does it use?

A 1:8 twist barrel chambered for 6.5 Grendel Type II, which stabilizes the long, high-BC 6.5mm bullets the cartridge is known for.
