The Daniel Defense 5.56mm NATO is a rugged, precision replacement barrel engineered for duty and tactical use. Built from Chrome Moly Vanadium and cold hammer forged for extended life and dimensional consistency, the 12.5‑inch profile delivers a compact, maneuverable package while maintaining the ballistic stability needed for common 5.56 NATO loads. The 1:7" twist rate is optimized for stabilizing heavier 62–77 grain projectiles, making this barrel a versatile choice for both duty and competition setups. Finished to tight tolerances and fitted for a carbine gas system with a low‑profile gas block, the assembly accepts standard muzzle devices and provides reliable, repeatable performance in demanding environments.

All of Daniel Defense’s Barrels offer high performance and a long lasting construction. All barrels are cold-hammer forged and made from 4150 Chrome Moly Vanadium steel with a mil-spec heavy phosphate coating as well as a chrome lining for superior durability. In addition, Daniel Defense Barrels are offered in a massive assortment of configurations, with options available for different lengths, gas-blocks, thread pitches, and calibers.
