Dd Bbl Assy 5.56 1-7 14.5" Lw Mid

The Daniel Defense DD Bbl Assy 5.56 1-7 14.5" LW Mid is a cold hammer-forged rifle barrel assembly designed for professional-grade accuracy and durability in tactical, law enforcement, and military applications. This mid-length gas system barrel is engineered to meet the performance demands of operators who rely on their rifles in high-stress environments where reliability and precision are essential.

The 14.5-inch profile balances velocity retention with compact handling, making it ideal for close-quarters work, vehicle operations, and dynamic entry scenarios. Cold hammer forging, a proven metallurgical process, applies intense hydraulic pressure to forge the barrel blank, resulting in a denser, more uniform grain structure that enhances barrel life and shot accuracy. The 1-7 twist rate stabilizes a wide range of 5.56mm ammunition, from lighter 55-grain to heavier 77-grain loads.

This barrel assembly is perfect for operators building precision 5.56 platforms or upgrading existing rifles. The mid-length gas tube provides a moderate impulse cycle, reducing bolt carrier velocity and wear compared to carbine-length systems, while ensuring reliable function in both suppressed and unsuppressed applications. Additionally, the muzzle thread pitch is 1/2x28 TPI, making it compatible with a variety of muzzle devices.
