Steve's Review of Criterion Barrels AR-10 Rifle Length Nitrided Gas System Barrel

Haven't fired it yet, but I installed it on an Aero Precision M5E1 upper receiver. Fitment is perfect. Headspaced with a Lantac EBCG. No problems there. Rifling looks good with a polished black mirror finish. Checked feed and ejection with some snap caps today. Seems to be functional. Just need some ammo and glass so I can break it in. Thanks to Optics Planet for the great deal on it. Will update after break in.
Pros:
  • Very nice barrel for the price.
Cons:
  • None yet.
Best Used for:
  • Sending lead from point A to point B.
Would Recommend: Yes
