It’s just the upper that goes on an AR. No FFL needed.
One of my Class III AR-15s has two Tax Stamps: a “short barrel” and “silencer”. The barrel is 12”. It went thru in 2004 and took 4mos. Doesn’t the 11” barrel fall under NFA regs? I thought everything under 14” did.
I see it listed on GB as an SBR, so I guess it doesn’t need a Tax Stamp.

It’s a short barrel rifle.
A short barreled rifle is defined in the US Code, Title 18, Part I, Chapter, Sec. 921. as follows...
(8) The term ‘’short-barreled rifle’’ means a rifle having one or more barrels less than sixteen inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon, as modified, has an overall length of less than twenty-six inches.
