I would like to ask a question concerning my first SBR. The appropriate forms have been filled out, 5330.20 & 5320.1 form 1.
The rifle I wish to use is a Colt M4 Match Target that I own. I would like to send it to the gentlemen at ADCO to have the barrel cut to 14.5 inches after I receive the stamp.
I planned on sending a copy of the tax stamp along with the upper. Is the way I am proceeding about doing this correct or am I doing something improperly.
