Frequently Asked Questions

Does this barrel make my AR-15 an SBR? No. A barrel sold on its own is not a regulated firearm. Installing this barrel on a complete, already-assembled rifle lower with a shoulder stock requires an approved ATF Form 1 before assembly; building it as a pistol with no stock avoids that requirement entirely.

What twist rate does this barrel use? 1-in-7.5 with 5R rifling.

What gas block size does this barrel need? .750 inch.
