I have a 24" bull bbl upper w/ v match tube. Bbl has been coated black from gas block forward. 1/8 twist. 95% plus condition. No B/C/CH. Very accurate but I need something for 3 Gun that is a bit lighter. NO 16" GUNS PLEASE. 18" might work.
Looking for 20" flattop from quality maker. Bushmaster, Armalite, Rock River, etc.
Colt would be OK if it is small front pivot pin.
