The Diamondback 5.56 NATO 16" carbine-length barrel is built for shooters who want a dependable replacement or upgrade barrel for AR-15 builds. Whether you're refreshing a worn rifle, experimenting with different barrel profiles, or assembling a dedicated carbine, this Diamondback barrel delivers the precision and durability expected from a quality US-made component. The 16-inch length strikes the balance AR enthusiasts favor: manageable in tight spaces, quick-handling in the field, and paired with a carbine-length gas system for reliable cycling without excessive gas tube wear.
Constructed from 4150 chromoly vanadium steel and finished in black nitride, this barrel resists corrosion and handles extended shooting sessions. The 1:8 twist rate stabilizes a wide range of 5.56 loads—from lighter 55-grain match ammunition to heavier 77-grain rounds—making it equally at home at the range, in a hunting build, or on duty. Button rifling with 5-groove geometry and 11-degree target crown ensure consistent accuracy, while M4 feed ramps maintain compatibility with standard AR-15 upper receivers and ammunition feeding. No threading means you'll configure the muzzle to suit your setup: suppressor-ready, flash hider, or bare.
This is the kind of straightforward component that works when you need it to. It's not flashy, but it doesn't need to be—just solid steel and proven geometry that lets you focus on the shooting.
