All Daniel Defense Cold Hammer Forged AR-15 Barrels are constructed of Mil-Spec 4150 Chrome Moly Vanadium Steel that is hydraulically shaped by carbide steel hammers around a precision machined mandrel to form the chamber, lands, and grooves. This Hammer Forging process creates a defect-free bore with the most consistent chamber possible, and each of Daniel Defense's barrels undergoes a Magnetic Particle Inspection (MPI) test to ensure this standard of perfection is achieved. All stripped barrels come equipped with an A4 Barrel Extension with extended M4 Feed Ramps for enhanced feeding reliability and a pre-installed locator pin.
This 16" AR-15 Barrel is perfect for a featherweight build due to its Lightweight Profile that eliminates all excess weight and bulk, resulting in an easy-carrying, fast-cooling and lively-handling rifle. Additional features include a Chrome Lined Chamber and Bore for enhanced wear and corrosion resistance. The barrel's 5.56x45mm NATO Chamber is fully compatible and safe for use with both surplus mil-spec and commercial ammunition, while its 1 in 7" Rifling Twist Rate is ideal for use with medium to heavy weight projectiles of up to about 77 grains.
