Description
This CMMG barrel sub-assembly gives you a ready-to-install solution for AR-15 builds without the hassle of sourcing components separately. Built from 4140 chromoly steel with a durable black nitride finish, it handles the demands of hunting, target shooting, and tactical training. The midlength gas system with medium taper profile balances recoil impulse and handling, while the 1:7″ twist stabilizes a wide range of 5.56 ammunition from 55-grain varmint rounds to heavier 77-grain match loads. The 1/2″-28 threaded muzzle accepts standard suppressors and brakes. Whether you’re finishing a rifle build or upgrading an existing platform, this is a solid choice for hunters and shooters who demand accuracy and reliability.
