Hi pafoa, I recently assembled an AR pistol, has 10.5" barrel, I tried to swap out the standard A2 bird cage with a 7" fake can muzzle brake ( I know I know, I'm lame , but I think it is gonna looks cool since the fake can and my barrel are both stainless lol) anyway, my question is , if I add this muzzle device onto my 10.5 barrel, does it makes my pistol become a rifle lol?

Base on my researching, this will not turn my pistol into a rifle , it's not part of the barrel unless I weld the extension onto the barrel which makes it permanent.

just wanna make sure it is still a pistol
