Product Description

The Diamondback DB Barrel is an OEM-style AR-15 replacement barrel built for reliable performance and long service life. This 16-inch, M4-contour barrel is chambered in 5.56x45mm NATO and made from durable 4150 chrome moly vanadium steel with a black nitride finish for enhanced wear and corrosion resistance. It features M4 feed ramps, a carbine-length gas system, and a 1:8 twist rate from button rifling—making it a versatile option for many common 5.56/.223 loads. The muzzle is threaded 1/2x28 for compatibility with many standard AR-15 muzzle devices.
