I have received a few different answers and still no clear answer. Call to ATF was not productive
Question is:
I have a Colt 6920 . I want to purchase a SBR upper in 300 BLK.
Now it is not a form 4 since I am not buying a complete firearm. It is a form 1, since I will be "building " a firearm, correct?
Now the question is as follows, as i understand it if i build a firearm on a form 1 I must engrave the receiver. So am iI required to engrave my pristine Colt lower with my information as i am going to switch between the .223 upper and the 300 BLK upper?
I know i can avoid this whole issue by buying a longer barreled upper but want an SBR just a bit lost on the legalities.
I know about constructive possession (intent) that is not the question.
The question is do i engrave the lower and do i use a form 1 as I am "building"
