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

Purchased an 18" .308 barrel for an AR10 build. The barrel itself is very nice, black nitride is flawless with a polished interior. Viewing through a borescope, the lands are all very distinct and machined well. Was easy to put an adjustable gas block on it as there is a mounting indent on the top of the barrel. Shooting wise, I was able to generate sub-MOA groups with the barrel using 168 grain factory match ammo. Higher grain ammo (e.g. 175/178) did not shoot as tightly (>MOA) for me. Plinking ammo (e.g. Winchester M80, Fiocchi 150gr, etc.) all shot around 1.25-2 MOA. I'm sure better shooters and/or hand loaders could get it tighter. Great barrel for the price!
Pros:
  • well machined
  • Sub-MOA capable
Cons:
  • None
Best Used for:
  • PRS or Plinking
Would Recommend: Yes
