Review by Ricky B. on 6 Jul 2025review stating Great barrel at a great price!
Don't be nervous to pull the trigger on this barrel. I've got over 1000 rounds of ammo through my 18" ultramatch fluted. It prints sub 1" MOA groups consistently when fed with at least 62gr NATO. With 77gr (particularly 77gr SMK bullets) you can get closer to sub . 5" MOA. Barrel is about as light as a rifle length barrel gets while retaining this type of rigidity and resonance period (yes including proof research / other boutique barrels. I noticed that cold bore shots vs a warm gun had a smaller deviation than that of other 16" / 18" barrels that I have shot with. Bottom line, if you're building an accurized ar15, this will meet or beat your expectations.

Seems to help with rise and recoil. Shoots much better than with just a flash supressor. Wish it had threads for a can on the outside, but two out of three ain't bad. Also priced well.
