If you prefer the rough look, you may need to look for an LE if they are still around. The three CR's I have seen all had a smoother finish.
I like having both.
I don’t prefer or turn my nose up at an external barrel finish......I just don’t care. What I do care about is the barrel extension, feed ramps, chamber, bore, gas journal/port, threads, and crown.......although I can fix most of that it needs be.
I’m not in the market for a $1250 Colt 6920. That is a great carbine at that price, for folks that are paying retail and can’t build their own. I get dealer pricing on most parts and can build a better AR for less money. I realize that ain’t an option for everyone.
