DBX57: Redefining the Personal Defense Weapon
At just 3 pounds and 15.25 inches, the DBX57 brings 5.7x28mm performance to a platform that fits in a backpack.
The DBX57 represents a new category for Diamondback — the personal defense weapon. Chambered in 5.7x28mm and weighing just 3 pounds, the DBX57 is purpose-built for vehicle carry, home defense, and personal protection.
Dual Gas Piston System
Unlike traditional AR direct impingement, the DBX57 uses a locked-breech dual gas piston system with 4 manually adjustable positions. This means reliable cycling across ammunition types with reduced fouling.
Monolithic Upper
Machined from billet 7075 aluminum, the monolithic upper provides maximum rigidity and a clean sight line for optics mounting.
AR-15 Compatibility
Standard AR-15 triggers, grips, safety selectors, and muzzle devices work with the DBX57. Customize it with the parts you already trust.
