Diamondback DBX 5.7x28mm Pistol 8" Barrel 20+1 Midnight Bronze

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

• 5.7x28mm chambering with 20-round magazine capacity for extended engagement capability
• 8-inch stainless steel threaded barrel (1/2x28 TPI) ready for suppressor attachment
• M-LOK compatible handguard allows modular accessory mounting
• Midnight Bronze Cerakote finish on aluminum Picatinny rail receiver provides corrosion resistance
• Magpul K-series grip offers improved ergonomics and control
• Full-length Picatinny top rail accommodates optics and backup iron sights
• Direct blowback action ensures reliable cycling with 5.7x28mm ammunition

The 5.7x28mm cartridge penetrates soft body armor while maintaining manageable recoil characteristics, making the DBX suitable for law enforcement applications and competitive shooting disciplines. The threaded barrel accepts standard 1/2x28 suppressors, reducing signature while maintaining the round's inherent accuracy. Weather-resistant Cerakote finish withstands environmental exposure during extended field use.
