Description
The Diamondback DB 556 barrel delivers the performance you need in a 16″ carbine-length package that balances handling and velocity. Its 1:8″ twist rate stabilizes a wide range of 5.56 NATO loads, from light varmint rounds to heavy match ammunition, while the heavy profile reduces harmonic vibration for tighter groups. Built from 4150 chrome moly vanadium steel with a durable nitride finish, this barrel resists corrosion and heat cycling—exactly what you want for a workhorse upper. The no-thread design gives you a clean finish and lets you customize your muzzle setup however you see fit. Whether you’re building a hunting rifle, competition gun, or defensive carbine, this is the kind of barrel that earns its spot in your safe.
