Diamondback Firearms DB15 Carbon Features The Diamondback Firearms DB15 Carbon is built around a 16 threaded barrel with a 1:8 twist rate and 1/2x28 thread pattern paired with a mid-length gas system that smooths out the recoil impulse for a flatter more comfortable shooting experience compared to carbine-length configurations. The forged 7075 T-6 aluminum receiver delivers military-grade strength and rigidity while the 15 aluminum M-LOK rail provides a full-length free-float accessory mounting platform for lights lasers and foregrips without compromising barrel accuracy. The Jesse James Blue Cerakote finish delivers long-term corrosion resistance in a distinctive head-turning aesthetic that sets this rifle apart on any range. The Magpul MOE collapsible stock and MOE grip give this Jesse James Blue 5.56 AR-style rifle a refined ergonomic shooting experience that adjusts the overall length from 32.75 to 36 for a comfortable fit for any shooter. The 2-position thumb safety provides positive intuitive fire control in any field or range condition. One included Gen 2 PMAG completes a fully configured visually distinctive package ready to run from day one.
