Diamondback DBX57 5.7x28mm Pistol Brace 20rd Black DB1629L001

The Diamondback DBX57 transforms the high-velocity 5.7x28mm cartridge into a compact, controllable platform that delivers rifle-like performance in a pistol-sized package. This black-finished model features a stabilizing brace configuration that enhances accuracy while maintaining portability for tactical applications.

What Makes This Different

The DBX57 chambers the 5.7x28mm cartridge, which penetrates soft body armor and maintains lethal velocity at extended ranges compared to traditional pistol calibers. The stabilizing brace design provides additional contact points for improved shot placement without requiring NFA registration. Diamondback's manufacturing process delivers consistent tolerances and reliable feeding with both SS195LF and SS197SR ammunition types.
