Update Review
This is an update to the review that I posted last May 2020. After about 800 rounds now, this barrel is way more that just awesome. I have settled on 125 gr ammo and this thing just spits'um out. Don't get me wrong it will eat anything, but I just prefer supersonic. With a red dot, I can hit 15 clays with 15 shots at 100 yards what I'll call "off-hand", meaning cheek on brace and not shouldered. So just buy it. As for AR15 Discounts, they are at the top of the list because of their extraordinary customer service and they will pull out all the stops to make sure that their customers are happy. I am a permanent customer and you will be too.

Solid Barrel overall
Good value for the price if you get it on sale. Certainly not a top end or operator quality, but for light range or HD applications, it will serve nicely.
USGreat barrel for the money!
Very well made and shoots great. Heat cycled mine a few times now with no noticeable drift and point of impact. Would highly recommend this barrel for a pistol/SBR build.
USQuality barrel
Fit and finish are excellent. Shoots well with no feeding issues. Quality barrel at a budget price.
US300 AAC barrel
Good fit and finish. Only 1 range trip and not real consistent with 200 grain subs or 120 supers. I’ll clean and try some more. So far groups about 8” at 50 yards.
