The Daniel Defense 16-inch M4 profile barrel in 5.56 NATO is a stripped, cold hammer forged barrel for AR-15 builds (Daniel Defense part no. 07-075-08174-018). It is forged from 4150 chrome moly vanadium steel, coated in mil-spec heavy phosphate on the outside and chrome lined in the bore. The carbine-length gas system, A4 barrel extension and 1/2×28 muzzle thread match the standard 16-inch carbine layout. A 1:7 twist handles a wide range of 5.56 bullet weights, so the barrel works for training, defensive use and long strings of fire.

Key Specifications

• The chambering is 5.56mm NATO, the designation Daniel Defense gives this barrel.
• The barrel length is 16 inches, the carbine length that pairs with the M4 profile.
• The twist rate is 1:7, which stabilizes heavier 5.56 bullets as well as lighter loads.
• The profile is M4, the carbine contour that matches the 16-inch length.
• Manufacturing is cold hammer forged, which Daniel Defense says gives the most accurate and longest-lasting barrel attainable.
• The steel is 4150 chrome moly vanadium, a strong alloy for sustained fire.
• The finish is mil-spec heavy phosphate outside and chrome lined inside, which fights corrosion and fouling.
• The gas system is carbine length with a .750-inch diameter at the gas port, so gas blocks and front sight bases sized for a .750-inch gas port diameter fit.
• The barrel extension is A4, which Daniel Defense builds into this barrel.
• The muzzle is threaded 1/2×28, and the stripped barrel weighs 1.75 pounds.
