The Diamondback DBX57 pistol features a proven locked breech, dual gas piston design. Chambered in the venerable 5.7x28mm cartridge, the pistol uses hard coat anodized 7075 aluminum upper and lower receivers, and a Magpul MOE-K pistol grip. It includes a DBX muzzle device and FN Five-seveN compatible magazine. This model has deleted the pistol brace and left in its place a standard rail for your choice of brace or sling mount, making for an even more compact pistol package. The full top rail allows for a standard red dot or a pair of flip-up sights if keeping it compact is your goal. With all these built-in features, this pistol is already a force to be reckoned with, now it's just waiting for your own touch to make it unstoppable!
