Diamondback Firearms DB1222C001 DB10 308 13.5" 21-Round Rifle

The Diamondback DB1222C001 DB10 .308 Winchester rifle delivers precision rifle performance in a compact, modular platform engineered for tactical shooters and serious enthusiasts. Chambered in .308 Win—the NATO standard full-power cartridge—this rifle combines a 13.5-inch Diamondback barrel, forged 7075 T-6 aluminum upper and lower receivers, and an A3 flattop configuration that accepts standard optic mounts without compromise. At 9.2 lbs, it balances meaningful firepower with genuine portability, making it suitable for precision work, intermediate-range engagement, and controlled environments where .308 Winchester's trajectory and terminal performance matter.

The rifle features a mid-length gas system and Mil Spec 8620 bolt carrier group with shot-peened and magnetic particle inspection finishing—standards that ensure function reliability across thermal and pressure cycles. The 9-inch M-LOK handguard provides modern rail mounting for lights, pressure switches, and other accessories without proprietary adapters. The included Magpul MOE-K grip and black padded buffer tube offer ergonomic control and cheek rest support. Magazine-fed from a 20-round Gen M3 PMAG, this rifle runs common .308 ammunition and accepts standard SR25/AR10-pattern magazines. The 1:10 right-hand twist rate stabilizes typical .308 projectiles from 155 to 175 grains, covering hunting, target, and general-purpose loadings.

This configuration serves shooters who prioritize compactness without sacrificing full-power rifle capability. Law enforcement precision teams, competitive shooters, and private security operators value short-barreled .308 platforms when space is constrained—vehicles, urban environments, buildings—but require the energy and range that .308 Winchester delivers. The flat-top receiver and 4150 CrMov barrel construction ensure repeatability and durability under sustained use. The carbon lower receiver keeps weight minimal while maintaining structural integrity. No sights are included; the flattop is optimized for optics-ready mounting.

Compared to longer-barreled .308 rifles, the DB1222C001 trades some velocity for maneuverability; compared to 5.56 NATO rifles, it gains substantial effective range and terminal energy at distance. This places it in the practical middle ground for operators who need full-rifle authority in a platform designed for close-quarters and intermediate-range work, with the accuracy foundation to reach out to 500+ yards with quality optics and ammunition.
