Dd Bbl Assy 5.56 1-7 16" M4 Car

The Daniel Defense Barrel Assembly 5.56 1-7 16" M4 Carbine is a precision-engineered upper receiver component designed for operators who demand repeatability and reliability in both training and duty environments. Built with Daniel Defense's commitment to tight tolerances and consistent quality, this barrel assembly serves as the foundation for accurate, durable performance across extended range sessions and operational use.

The 16-inch barrel in 5.56 NATO caliber with 1-7 twist rate is optimized for stabilizing a wide range of ammunition weights, from lighter 55-grain rounds to heavier 77-grain loadings. This twist rate represents the industry standard for modern 5.56 carbines and delivers consistent velocity and accuracy across the velocity spectrum typical of M4-platform weapons. The precise bore and chamber dimensions are held to Daniel Defense's manufacturing tolerances, ensuring minimal runout and maximum consistency shot-to-shot. Weighing 2.06 lbs, the assembly balances manageable weight with structural integrity required for sustained fire and demanding duty cycles.

This barrel assembly is engineered for law enforcement, military, and civilian shooters who maintain or upgrade existing M4 and AR-pattern carbines. The 16-inch configuration remains the most practical length for duty rifles, offering improved velocity over shorter barrels while maintaining maneuverability in vehicles, buildings, and tactical environments. Whether used for patrol rifle maintenance, precision range training, competition, or home defense, this Daniel Defense component delivers the manufacturing precision and durability expected from a recognized leader in small-arms component design. Compatible with standard M4-pattern upper receivers and lower assemblies.
