The Daniel Defense Barrel (brand part number 07-077-09173-018) is a 16-inch, midlength Government-profile barrel chambered in 5.56x45mm NATO and built from 4150 chrome-moly-vanadium steel with a black phosphate finish. Daniel Defense cold hammer forges the barrel, a process that produces a consistent chamber and a defect-free bore, and the Government profile keeps a heavier contour toward the muzzle for durability and heat management under sustained fire. At 16 inches, the barrel meets the federal minimum rifle barrel length on its own, making it a straightforward, complete option for a standard AR-15 build with no additional NFA considerations.
