Reviewer: Akujin
Easy to install. No issues with gas block install or alignment nice predrilled detent to help with gas block install. Clean threading for break/hider. Shoots great semi auto or....not. Could not be happier with this barrel.

5.0 Rating Great barrel for the money. - 4/8/2014
Reviewer: Ragnar
Fit, finish, and function are as expected. Great. Packaged to insure it arrived in perfect condition. Shoots great. The better the ammo, the better the groups that it prints. CMMG is known for great rifles and parts, this is no exception. I plan on using CMMG barrels on all my builds.
