Description
Built from quality 416R stainless steel and finished in durable nitride, this CMMG barrel sub-assembly delivers the reliability hunters and shooters expect from a name-brand component. The 6mm ARC cartridge splits the difference between .223 and .308—offering better ballistics and range than 5.56 without the recoil penalty of larger calibers, making it ideal for deer-sized game and distance shooting. At 16.10″ with a 1:7.50″ twist rate, this rifle-length barrel is threaded 5/8″-24 for suppressor mounting or muzzle devices. The medium taper profile keeps weight manageable while maintaining the rigidity serious shooters demand. Whether you’re building a new upper or refreshing an existing platform, CMMG’s sub-assembly spec takes the guesswork out of component compatibility.
