it is identical. the same lower can be either. however a lower born as a pistol can beme a rifle, and go back to being a pistol.Ok thanks. Can a lower that is labeled “pistol” but purchased as just a bare lower, be made into a rifle?
the law prohibits rifles from becoming pistols.
I don't own ANY rifle barrels, so all of my AR'S are pistols. If I did I would thoroughly document the lower being born a pistol FIRST.
