Excellent barrel!Review by Jeff
Sub moa with Federal 168 SMK. I was worried at first because the bolt would close on a Forster no go gauge. Tried a Clymer and all is well. There’s just something about where the Forster measures from. It’s on a retro themed iron sight AR-10 which is kind of sad because it’s so accurate it really deserves a scope. Out of the ten 10 ARs I’ve had over the years it’s the most accurate. When I get around to building a 6.5 upper for it, it will have some nice glass and another Ballistic Advantage barrel.

Very well made, accurate, beautiful finish, RecommendedReview by Doug
Purchased this for an Aero M5 build, and could not be happier. The finish on the barrel is deep rich black satin, beautiful and well machined throughout. Went together perfect in the build, now Aero and BA are teamed up in Aero factory builds. Recently did some reloading tests with Nosler 165 BT, last batch at 100 yards had Varget 44 gr yield .87" three shot group, and TAC with 42 gr. .75" three shot group!
The groups do open up soon after the barrel gets hot, so keep that in mind for your own use. (Posted on 3/22/2017)
