I know you can make an AR pistol into a rifle, but read you can't make a AR rifle into a pistol, unless you stamp it.
From ATF's website.
"Can I lawfully make a rifle into a pistol without registering that firearm?
No. A firearm that was originally a rifle would be classified as a "weapon made from a rifle" if it has either a barrel less than 16 inches in length or an overall length of less than 26 inches. If an individual wishes to make an NFA firearm, they must first submit ATF Form 1 (Application to Make and Register a Firearm), pay a $200.00 making tax, and receive approval of the application from ATF before converting the firearm.
[18 U.S.C. § 921(a)(3); 26 U.S.C. § 5845(a)(3)-(4)]"
I had 2 SBR AR's before all this happened, I also had a braced 7" AR that I did the no tax stamp on. I wanted to keep it as a pistol for road trips...truck gun.
I guess I'd have to buy another AR pistol lower if the brace law goes out.
Still have my brace.
