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.
Can I shoot both 5.56 NATO and .223 Remington?
Yes. A 5.56 NATO or .223 Wylde chamber safely fires both 5.56 NATO and .223 Remington ammunition.
Is a bolt carrier group included?
Yes. This upper ships with a bolt carrier group, so it is ready to install on a compatible AR-15 lower.
What twist rate does it use?
A 1:7 twist, the mil-spec rate that stabilizes 55 gr through heavy 77 gr loads.
What does the shroud do?
It slips over the muzzle device and pushes blast forward, away from the shooter.
