Diamondback DB15 Features The Diamondback DB15 is chambered in .338 ARC a cartridge designed to deliver more downrange energy than typical AR pistol calibers while still cycling reliably in a gas-operated semi-automatic action. The black nitride finish on the chrome moly vanadium barrel provides excellent corrosion resistance and wear durability an important consideration for a barrel run hard through repeated range sessions. A 1:5 inch twist rate is cut specifically to stabilize the heavier bullets typical of the .338 ARC cartridge supporting consistent accuracy at extended ranges for a pistol-length platform. The threaded muzzle accepts a 5/8x24 thread pattern giving shooters the option to add a muzzle device or suppressor to manage recoil and blast. An ambidextrous Radian Talon safety gives shooters fast intuitive manipulation from either shooting hand a meaningful advantage in a compact pistol platform used for close-range applications. The M-LOK compatible handguard offers a lightweight low-profile way to mount lights lasers or foregrips exactly where a shooter wants them while the black hardcoat anodized aluminum receiver with an integrated Picatinny rail provides a durable optics mounting surface. The included SB Tactical SBA5 brace and black Magpul grip round out a complete ready-to-run package right out of the box. For shooters looking for a hard-hitting compact AR pistol chambered in a genuinely capable cartridge the DB15 delivers a complete solution.
