Great Barrel
I wanted a 20" barrel and when I found this on sale plus being CHF, it was a done deal. Rather than a swap, I built a free float upper. Before install, I thoroughly cleaned and polished the inside of the barrel so that it was clean as possible for break in. Took it to my range today and ran some bulk 55 grain FMJ for getting a scope on paper and break in. There was a slight cross wind and I was using a 50 yard target. My expectations were easily met, getting very tight groups, just tinkering with less than ideal conditions. I do believe that this barrel will get 1 MOA groups with appropriate ammunition as advertised. Fit and finish were great and I was not looking for a really expensive barrel in the first place. Once I get to run some premium rounds through it, I have no doubt that I will continue to be pleased with this purchase.

USNBS 20” CHF barrel
Great looking barrel at a budget price point , was gonna use on a m16 clone, but decided to build a pretty gun . Picked up several other budget deals during the holidays, finally got time to build my upper. Used my favorite Midwest industries URR . Went together like a charm. I can’t brag on the grouping as I haven’t put on an optic and ran it . But looks great. Finish was great. No flaws that I saw. Was shipped fast. Ar 15 discounts had some great deal. Grab em when you can.
