The Diamondback DBX delivers the flat trajectory and armor-piercing capabilities of the 5.7x28mm cartridge in a compact, AR-style pistol platform. This specialized firearm bridges the gap between traditional handguns and rifle performance, offering superior ballistics in close-quarters scenarios.
What Makes This Different
Unlike conventional pistol calibers, the 5.7x28mm round maintains velocity and energy at extended ranges while producing minimal recoil. The DBX features a direct blowback operating system specifically engineered for the high-pressure 5.7x28mm cartridge, eliminating the complexity of gas systems found in rifle platforms. The 8-inch stainless steel barrel maximizes the cartridge's potential while maintaining overall compactness.Key Features
