Just read the new NRA Rifleman and see where the ATF have clarified the rifle/pistol parts controversy. Am I getting this correct that as citizens we are alowed to convert a pistol to a rifle then back to a pistol, but if the weapon left the factory as a rifle, we can't convert it to a pistol? Is it now true that if you purchase a reciever and build a rifle, once it is complete you can't change it to a pistol in the future? Just gathering info. Thanks.
