Exceeds the accuracy guaranteeReview by Scott
Replaced a lesser yet similarly priced barrel with this guy and have only purchased BA barrels since. Easily is a better barrel than I am shooter. Sub MOA all day long. (Posted on 1/11/2019)
excellent barrelReview by jeff
great product and excellent shipping . I recieved the barrel in 4 buisness days , The front sight tower , barrel nut and handguard ring were all installed properly and the front sight was aligned perfect . I replaced a goverment profile barrel from a different manufacture which i was just not satisfied with . My rifle is pretty plain jane standard hand guards , buttstock and mil-spec trigger . I am shooting 2.5 moa with 60 grain v-max and using a carry handle sight at 100 yds . I think I am going to mount my 10x super sniper on the rifle and see what it will really do . thank you B.A for a great product I am a very happy customer .

Shoots 1/2 MOA at over 300 yards with factory ammo. I built the gun for long rang precision shooting. I set up a 10X10 steel target at 600yds hit it 7out of 10 shots. This barrel shoots great. (Posted on 1/27/2017)
