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.

Is it suppressor ready?

Yes. The muzzle is threaded 5/8x24, a common pitch for 6.5mm and .30 caliber muzzle devices and suppressor mounts.
