Well, I’m really wanting to go full on SBR and have some fun either at the range, or in some classes. Build idea would be a BCM complete lower, and top it off with a BCM 12.5" complete upper w/a MS4D flash comp.
So to stay out of the clutches of John Law, am I correct in getting the lower first, then submitting a form 1 on the lower having it changed to a SBR, the slapping the 12.5" upper on and being good to go?
Do I need another stamp for the upper or will anything still be an issue being under 16.1" in barrel length? Just want to keep on the right side of the law.
