If you're on the fence about it, G E T I T
Honestly one of the best barrels i've ever had. Took 20 or so rounds to break this bad boy in but after that it was smooth as butter. After a 36 yard zero i rang steel out to 200 yards no issue.
Awesome barrel for the money

Awesome barrel for the money In my opinion! Made a pistol build for home defense and used this barrel! Ran some federal 556 55gr, PPU 223 75gr match bthp, and frontier 556 75gr match bthp with no problems! Limited range at the time 17yds! Barrel took about 15 rounds to break in and seemed to like the frontier the best but the brands were good with no malfunctions! First time using the bear creek arsenal bcg too seemed to work fine! Need to get out to 25-50 yds!
