If it shoots full-auto, it was either born that way or it is jailbait.
I thought that was the case but I was not sure.
I don’t think that’s true.
If they have a registered sear they can convert an AR into a fully automatic rifle.
People with registered HK sears have been converting HK 94’s into MP-5’s, legally, as well as converting AUG’s into full-auto with registered full-auto trigger packs.
