no. It can be in whatever legal configurations it was without the stamp when it was transferred to you.Not trying to hijack thread but one question I have concerning the Form 1 process is does my lower have to go to jail while I wait on the tax stamp?
so if it started as a lower, it can be a pistol or rifle
if it started as a pistol, can be that or a rifle.
if it started as a rifle, it can stay a rifle.
