Diamondback Firearms DB1222C071 DB10 308 13.5" 21-Round Pistol

The Diamondback DB1222C071 DB10 .308 Winchester is a mid-length pistol configured around the venerable .308 Win cartridge, delivering accurate fire in a compact platform suited to close-quarters and transitional environments. Built on a forged 7075-T6 aluminum A3 flattop upper receiver and carbon-fiber lower, this 9.2-pound system balances weight savings with structural integrity demanded by serious operators and precision shooters. The 13.5-inch Diamondback barrel with 4150 CrMov steel and black nitride finish is optimized for mid-length gas dwell, supporting reliable extraction across a wide range of .308 ammunition loads.

The receiver package pairs a shot-peened, magnetic-particle-inspected mil-spec 8620 carrier with a mid-length gas system, engineering that reduces carrier tilt and extends component service life under sustained fire. The 9-inch M-LOK handguard provides multiple mounting points for lights, lasers, or support grips, while the Magpul MOE-K grip delivers ergonomic control and a lower bore axis suitable for precision work. A 20-round PMAG Gen M3 magazine ships with the rifle, and the padded buffer tube with foam pad mitigates recoil energy during rapid strings. The A2 muzzle device manages flash and serves as a platform for future suppressor or muzzle-brake adaptation in configurations where federal regulations permit.

This configuration addresses intermediate shooters, designated marksmen, and operators requiring .308 power in a handheld format for hunting, home defense, or training environments where full-size rifle logistics are impractical. The compact barrel length trades some velocity against the standard 20-inch rifle, a tradeoff that remains acceptable for targets within 200 yards where energy retention and accuracy matter more than maximum range performance. Shooters familiar with modern tactical rifle ergonomics will find the controls intuitive and the modular handguard approach consistent with current industry standards.
