BA Barrel of the Week: 5.56 7.5″ BA Hanson Performance Series

I wrote two articles regard 7.5″ AR-15 barrels chambered in 5.56. They are among the most heavily visited posts on JTT. The first was about how, while not an ideal length for the 5.56, these types of barrels are finally viable for specific purposes thanks to advances in barrels (like the one that is the subject of this p0st), ammo, and muzzle devices. The second was in response to the internet’s over-reaction concerning the ballistics of said barrels.


If you are interested in starting your own 7.5″ AR pistol or SBR build, this barrel will be tough to beat. The BA Hanson barrel profile is well designed and Ballistic Advantage is very conservative with the gas port on these barrels. All that coupled with the fact that it comes with a pinned low-profile gas block and the Barrel of the Week sale price make this a very tempting deal.

Check out the 5.56 7.5″ BA Hanson Performance Series Barrel at Ballistic Advantage.
