The government profile keeps weight manageable without sacrificing durability. CMC's attention to detail in machining and finish work means you're getting a barrel built to last through thousands of rounds.

This barrel works equally well in compact carbine builds or full-size rifles. It's the kind of no-nonsense component that lets you focus on what matters: shooting accurately and reliably.
