Okay, I took the first step on this and purchased an 11.5" light profile AR barrel. The next purchase will be a Sig SB15 AR pistol stabilizer. I'll keep that configuration while my SBR paperwork goes through the long arduous journey for approval then prchase a three position collapsible butt stock and install it.
Should look like this when done
