Diamondback DB15 Features The Diamondback DB15 is chambered in .300 AAC Blackout and built around a 10 inch heavy threaded barrel machined from Chrome Moly Vanadium and finished in Black Nitride for corrosion resistance and a tough low-maintenance surface. A 1 in 8 inch right-hand twist rate is matched to stabilize the heavier bullet weights that make .300 AAC Blackout effective in a short barrel and an A2 flash hider caps the muzzle to reduce visible signature. The Picatinny rail aluminum receiver is finished in Flat Dark Earth Cerakote giving the upper a durable color-coordinated appearance that pairs with the rest of the build. An M-LOK handguard provides mounting space for lights grips and other accessories along the forend. The SB Tactical SBA3 brace is finished in Flat Dark Earth synthetic material to match the rest of the build giving the shooter an adjustable support point for stabilized one-handed shooting. A Magpul MOE K2 grip in Flat Dark Earth continues the color theme through the lower which also carries a mil-spec trigger and a thumb safety for user familiarity. Feeding is handled by an included 30 round Magpul Gen3 PMAG giving the shooter ample capacity for range sessions or defensive use. At roughly 9.16 pounds the DB15 brings together compact size a hard-hitting cartridge and a thoughtfully finished build for shooters who want a capable close-range AR pistol platform.
