Frequently Asked Questions
Does a 13.9-inch barrel have any compliance considerations? This is a bare barrel sold with no lower receiver included. A barrel under 16 inches only becomes a regulated short-barreled rifle once it is assembled on a complete rifle-configured firearm; consult the ATF or qualified legal counsel on a pinned/welded muzzle device or other compliant configuration before building with it.
How does a government profile differ from a pencil profile? A government profile carries more material forward of the chamber than a pencil profile, adding weight and rigidity while the pencil profile stays lighter.
