The Diamondback DB10 is a .308 Winchester AR pistol built for shooters who want serious firepower in a compact, maneuverable package. This 13.5" barreled rifle-caliber pistol pairs a mid-length gas system with a SB Tactical SBA3 brace, delivering a balance of control and portability that works for both range training and home defense. At 5.1 lbs, it handles like a modern tactical pistol while delivering the stopping power and range of a full rifle cartridge—ideal for those who need capability without the footprint of a traditional AR.
Built on Diamondback's forged 7075 T-6 aluminum lower and A3 flattop upper, this DB10 starts with a solid platform. The 13" M-LOK handguard gives you mounting flexibility for lights, lasers, or other accessories, while the Magpul MOE K grip and included Magpul Gen M3 20-round PMAG round out a functional, no-frills setup. The barrel is nitride-treated 4150 CrMov steel with a 1:10 twist and 5/8x24 threading—ready for a suppressor or brake if you choose to add one later. The A2 flash hider comes standard. Mil-spec trigger and bolt carrier group keep maintenance straightforward and parts support accessible.
This is a stripped-down, working firearm for shooters who value reliability and practicality over trendy features. The collapsed length of 30" keeps the profile tight, making it at home in a truck, bag, or behind a door. Whether you're testing a new cartridge, running drills at the range, or looking for a home-defense AR pistol with rifle-class power, the DB10 delivers genuine utility without the weight or complexity.
