What are the federal considerations to AR pistols?
The AR can swap barrel lengths and calibers with a simple upper swap, except you cant just go and change your AR rifle into a pistol and call it legal. Once a rifle, always a rifle. So with that in mind, if you change your AR rifle into a pistol, you just manufactured an SBR illegally. Likewise, if you buy a used lower, you cant make it into a pistol unless youre sure it was always a pistol. If it was a rifle in its life, even for a nanosecond, turning it into a pistol is manufacturing an SBR.
