Since you already ordered one you probably know that the barrels are made by T/C and are 1/9 twist and nitride coated. They are not chrome lined. The biggest bummer is that the FSB is not F marked. Another annoyance was that the original hand guards were terrible and loose as a goose. I put a set of Cav Arms hand guards on mine and they are tight now. I have read that DSA is now shipping their uppers with the Cav Arms hand guards on them now as a fix for the loose hand guards that they originally shipped with. Mine is pretty accurate. I usually average 3 inch groups off the bench using my red dot site at 100 yds with Fiocchi 55gr ammo. I am sure a better shooter than I could do better with it though.
