⚠️ NFA Compliance Note:
The 13.7″ barrel does not meet the 16″ minimum rifle length on its own. To avoid classification as a short-barreled rifle (SBR), a muzzle device that brings the total barrel length to at least 16″ must be permanently pinned and welded. Alternatively, this upper can be used on a registered SBR or pistol lower.
