CMMG is neither great nor poor. Some of their barrels have had thread concentricity issues. Suitable for a flash hider, but not suitable for a silencer. I have had a baffle strike and launched my $1000 suppressor before (bad ammo not bad barrel) and if you intend to silence it Id look elsewhere but the bargin bins are perfectly servicable otherwise. Luckily AAC repaired my silencer for free.
