Featuring a lightweight contour designed by American Defense MFG, Criterion Barrels Inc. is proud to announce the introduction of a new line of salt bath nitrided AR-15 barrels. Machined from ordnance grade 4150 CMV (chrome moly vanadium) steel with a hand lapped and polished bore and chamber, these ADM barrels produce minimal fouling with the added corrosion resistance inherent in the salt bath nitriding process. Each barrel is dimpled to allow for easy gas block alignment (these barrels are contoured to accept a .750 gas block). Also included is an M4 barrel extension. Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith.
