it's a average barrel
I bought this barrel a few months ago. it has about 600 rounds through it. shoots 1.5 moa. some days better if I'm on my game. I have not had any problems. fit and finish is great. rifling looks really good. cleans easily. just think for me I should of spent the extra 100 dollars and got a Odin works 223 wylde barrel instead but it's a good reliable barrel. cmmg does not guarantee it to be under 3 moa tho. I've already spoke to there costumer service. they said call if it's not in that range. to me that is unacceptable at 100 yards.
