Primary Caliber: 5.7x28mm
The Diamondback DBX is a 5.7x28mm large-format pistol built on a forged, monolithic 7075-T6 aluminum upper with a 6061 M-LOK handguard. A locked-breech dual gas-piston action tames the high-velocity 5.7 cartridge while a reversible charging handle, Magpul MOE K grip and 8 in threaded barrel with a Diamondback flash hider make it a compact, suppressor- and brace-ready platform. It feeds from 20-round magazines compatible with FN Five-seveN pattern magazines.
