This barrel has been finished with a protective Melonite coating that surface-hardens the metal. Also referred to as Salt Bath Nitriding, this treatment produces an extremely hard, slick surface on steel that resists carbon adhesion and increases corrosion resistance, making for easier cleaning and maintenance.
This 18" AR-15 Barrel features Daniel Defense's exclusive Strength 2 Weight (S2W) contour for the perfect balance of barrel weight and stiffness, while the 5.56x45mm NATO chamber allows for full compatibility with both surplus mil-spec and commercial ammunition. The barrel's 1 in 7" Rifling Twist Rate is ideal for use with medium to heavy weight projectiles of up to about 77 grains. Proudly manufactured in the USA.
