Excellent barrel worth a look

by -

Excellent barrel, it fit very snug into my upper and shoots accurate up to 100 yards. Probably farther but that's as far as I've tested it so far. Very happy with my purchase

Great Groupings


After breaking this barrel in it was able to make groupings at 100 yards better than any other AR barrel I have in my "arsenal". You hear it a lot but this is the truth this barrel is more accurate than I am. For this price range barrel I'd say you couldn't do much better

Perfect for a standard build.


Just received the barrel today. Looks great fits very snug with my Aero Precision upper receiver. I will update when I put rounds through it.

One of the best purchases of 2017!!

Ordered this barrel along with other parts before Christmas, and received my entire order on time......Bravo Primary Arms!! I was impressed with the fit and finish of the barrel, installed it into my Upper receiver and assembled everything. Took it out twice over the holidays and was impressed with the groupings, very accurate even with standard 55 grain M193 producing 1-2 inch groups, with some Federal premium it was grouping 3/4 inch groups at 100 yards. I'm a happy camper!!!

High quality barrel!

I got this barrel for my Aero Precision M4E1 build. I couldn't be happier with the quality of this barrel. Looks great under the S One 15" Atlas handguard too. The best part was catching it on sale! Thanks PA!

Would recommend all day!

Arrived within a week of ordering on sale and came very well wrapped within a tube inside of a box with other parts. Assembled my upper and hit the range the next day with zero malfunctions after 200rds, barrel looks like top notch quality. I’m not an MOA guy, all I’m worried about is man size target at 100yds and this barrel does that easily with no magnification, great brand you won’t regret it, thank you primary arms!
