Diamondback Firearms DB1731T001 DB15 350 16" 6-Round Threaded Barrel Pistol

The Diamondback DB15 350 Legend 5+1/10+1 16" Nitride Treated Threaded Barrel with Compensator represents a purpose-built modern sporting rifle designed for hunters, sport shooters, and tactical operators seeking a compact, versatile platform in an intermediate cartridge. The 350 Legend cartridge offers sub-sonic performance, reduced recoil, and effective medium-range capability—making this rifle ideal for suppressed fire, hunting applications, and shooters transitioning from pistol-caliber platforms. At 8.6 pounds with a 39.8-inch overall length, this Diamondback delivers maneuverability without sacrificing sight radius or control.

Built on precision-machined 7075-T6 aluminum upper and lower receivers, the DB15 features a heavy 4150 chrome-moly barrel with nitride treatment for superior corrosion resistance and service life. The integrated compensator reduces muzzle rise and side deflection on follow-up shots, critical for rapid target engagement. A Mil-Spec 8620 bolt carrier with shot-peening ensures durability under sustained fire, while the pistol-length gas system optimizes cycle rate and reliability. The 15-inch M-LOK handguard provides modern mounting flexibility for accessories, tactical lights, and optics without rail obstruction. Factory Magpul MOE K2 grip and CTR stock combine ergonomic control with repeatable shouldering geometry—standard equipment on duty rifles.

This configuration benefits law enforcement, military, and civilian operators evaluating intermediate-cartridge rifles for training or duty use. The threaded muzzle accepts standard 1/2x28 suppressors, flash hiders, or muzzle devices without modification. Shooters should confirm local regulations regarding suppressor legality and barrel threading before purchase. The A3 flat-top upper accepts Picatinny-mounted optics of any height, from ACOGs to modern prism and red-dot systems. Magazine compatibility follows standard AR-platform feed systems; the rifle ships with factory magazines supporting both 5-round and 10-round configurations for jurisdictional compliance. For operators seeking a lightweight, configurable platform in an efficient, controllable cartridge, this Diamondback delivers proven reliability backed by lifetime manufacturer support.
