FAQ

Will this upper fit my AR-15 lower?

Yes. It fits any standard mil-spec AR-15 lower receiver and uses a standard 5.56 bolt carrier group and STANAG/AR-15 magazines.

What is a .223 Wylde chamber?

A hybrid chamber that safely fires both 5.56 NATO and .223 Remington while giving the tighter accuracy of a .223-style throat.

Is a bolt carrier group included?

No. The bolt carrier group is sold separately; any standard 5.56 AR-15 BCG will work.

What twist rate does it use?

A 1:8 twist, a versatile rate for 55 gr to 77 gr bullets.
