    Good barrel, Better Company to Buy From.

    Barrel works as advertised. Not a $300 barrel, so it probably won't last through 100k rounds, but it's exactly what I needed. The biggest reason for 5 stars is just AT3 Tactical, hands down the best customer service I've come across building AR's from the internet. Had a problem with a defective product, let them know, received a response within 3 hours, they sent out a new one, and a return box for the defective one. You can buy from these guys with all confidence that you'll be satisfied or they'll make it right. The pic is sighting in with AT3's 2 MOA Red Dot firing 3 round groups, and checking placement. 75 yds with 1X optics, I'm more than satisfied with everything AT3 Tactical.
