Product Overview

The Diamondback DBX57 5.7x28mm semi-auto tactical pistol brings modern AR platform efficiency to a compact, high-capacity package. Built on a locked-breech dual gas piston operating system, this 8-inch-barrel pistol delivers the ergonomic familiarity of AR-pattern controls in a form factor that works for shooters who want less gun but not less capability. The 5.7x28mm cartridge pairs low recoil with substantial magazine capacity—the DBX57 feeds 20-round FN Five-SeveN–compatible magazines—making it equally at home for range training, tactical drills, or as a home-defense option when space or capacity matters.

The frame is 7075 aluminum with hard-coat anodize, a material choice that speaks to durability without excess weight. The 6061 aluminum handguard mirrors that construction and includes M-LOK slots for adding lights, lasers, or grips to suit your mission. A standard AR15 mil-spec trigger keeps the manual of arms intuitive if you already run AR rifles. The 1/2x28 RH-threaded muzzle comes with a Diamondback muzzle device already installed, so you're ready to shoot or swap suppressors if your local laws allow. Midnight bronze finish gives it a purposeful, working aesthetic that doesn't scream for attention.

At just 3 pounds with an empty magazine, the DBX57 handles lightly without feeling fragile. The overall footprint—15.25 inches long, 7.3 inches tall, 1.75 inches wide—keeps it maneuverable indoors or in tight spaces. Gripped with a MagPul MOE K, it feels sure in hand whether you shoot with a high grip or prefer the modularity to swap controls later. This is a pistol for shooters who want M-LOK modularity, FN-compatible magazine logistics, and the straight-shooting nature of a piston gun, all in midnight bronze.
