The CMMG 55DA36F is a low-profile rifle barrel engineered for shooters who demand precision without compromise. Built from chrome moly steel, this CMMG barrel delivers the durability and consistency that ARs and modern sporting rifles depend on—whether you're running drills at the range, hunting, or pushing distances. CMMG's reputation for quality manufacturing means you get a barrel that handles repeated firing cycles and cleaning without degradation, and the low-profile design integrates cleanly into most standard rifle setups.
Chrome moly steel is a proven choice in precision rifle barrels. It resists wear from high-round-count shooting, maintains bore straightness, and handles the stress of rapid fire better than lighter materials. The low-profile geometry keeps your rifle's profile compact and reduces unnecessary weight—useful whether you're carrying for miles or setting up for precision work on the bench.
This barrel is built for serious shooters: reloaders who watch brass closely, hunters who demand reliability in the field, and range competitors who know that barrel quality directly affects group size and shot-to-shot consistency. CMMG has been a trusted name in AR parts and uppers for years, and this barrel carries that reputation forward.
