Factory-forged 7075-T6 aluminum receivers wear an even Flat Dark Earth Cerakote and carry Diamondback’s shield logo, giving the rifle a distinctive look that resists corrosion and abrasion.
The 16-inch barrel is made from 4150 CrMoV steel, treated with a black-nitride finish for long life, and threaded 1/2-28 with an A2 flash hider. A 1:8 right-hand twist balances common 55- to 77-grain 5.56 NATO loads.
A mid-length gas system works with the free-float 13-inch aluminum M-LOK handguard to soften recoil impulse and keep accessories cool. Full-length Picatinny rail space up top simplifies mounting optics or back-up sights.
Custom touches include the Mossberg six-position collapsible stock with integral recoil pad and a black polymer vertical foregrip for positive control. A Magpul MOE pistol grip rounds out the ergonomic upgrades.
Built on the familiar direct-impingement, rotating-bolt action, this DB15 remains fully compatible with standard AR-15 magazines, parts, and accessories while offering a factory MSRP of $850.
