Hey guys
Almost done my ar build, the gunsmith is putting on the barrel as i dont have a vice, bench ect
My question is, the lower i have is only registered as a lower receiver right now. When i complete my upper do i have to call the cfo and let them know the barrel length and all because its a complete firearm now? Or do i just leave it registered as a lower only?
Not sure. First build.
Thank you.
