The 4140 Chrome Moly steel barrel boasts a 1:7 twist and a corrosion-resistant salt bath nitride finish for exceptional strength and improved accuracy potential, and an adjustable gas block allows you to fine-tune the gas system for enhanced performance with any rifle load. Plus, this barrel comes with a factory-mounted CMMG ZEROED linear compensator for reduced recoil and enhanced accuracy potential. Lifetime warranty.
