Frequently Asked Questions

Does this include a lower receiver?
No, this is a complete upper assembly only; it ships without a lower receiver or fire control group.

Are there legal restrictions on this barrel length?
At 12.5 inches, this barrel is well under the 16-inch federal minimum for a rifle-configured (shouldered/stocked) firearm. It’s intended for a pistol-configured (braced, no stock) build. Installing a sub-16-inch-barreled upper on an already-assembled, shouldered rifle lower without prior ATF Form 1 approval creates an illegal, unregistered short-barreled rifle (SBR).
