Update to my 2017 reviewReview by Brian
Had a chance to seriously test this setup and do my part benched. Started out using .223 Wolf Gold, managed a best at or just under 3" 5 shot groups at 100/y (obviously not match grade ammo). Switched over to Sig 77/gr Sierra MatchKing OTM Elite Performance ammo. WOW! Pulled off a best 5 shot group at 3/4", most were at 1" or better out of eight 5 shot groups. That was also using a NOS Leupold scope 3x9 Tactical. (Posted on 8/4/2018)
Excellent barrelReview by Brian
Purchased my mid-length back in May 2016. No issues. Coupled with an Aero upper M4E1 and lower, plus an Aero 12" MLock rail, she plays nicely. (Posted on 9/1/2017)
Truly outstanding Review by Izzy
Purchased without knowing to much background on BA barrels but let me tell you i was amazed with the quality and craftsmanship now what was even more amazing is how accurate this barrel is it will shoot 62gr to 77 gr loads all day long into 3/4" groups @ 100 yds with boring regularity and the velocity obtained seem to be about 50 fps faster than normal with bullet weights mentioned purchase on you wont look back thanks BA (Posted on 8/13/2017)

Used this barrel for a predator/Scoped back-up patrol rifle after breaking barrel in as suggested. Groups are easily sub MOA with 77gr rounds.

Hanson Series Barrels

" BA Hanson Series Barrels provide a lightweight feel without lightweight limitations. Every barrel in the BA Hanson Series was designed specifically to its length and caliber to yield the best results with every aspect taken into consideration. It is truly ideal for how the AR was meant to perform. With the BA Hanson Profile, we found a more efficient way to harness a bullet's energy while limiting felt recoil considerably. The balanced feel and overall performance of a Hanson barrel will create a more organic relationship between you and your rifle. It will simply be an extension of you! "
