Diamondback DBX Pistol | 5.7×28 | 8″ | 20+1 | DB1614L071

The Diamondback DBX is a semi-automatic tactical pistol chambered in 5.7 x 28 mm with an 8″ threaded barrel and a 20-round magazine capacity. It uses a locked-breech, dual gas piston operating system and rides on a forged 7075 T-6 aluminum receiver with a 6061 M-LOK handguard. The DBX is configured for optics and includes a DBX muzzle device with 1/2×28 RH threads; a low-profile red-dot such as the Vortex Venom would pair well and remains well under $1,000.

This platform suits precision-oriented range work and competitive target shooting where controllability, lightweight construction, and higher-velocity small-caliber performance are priorities. It ships with one 20-round FN Five-seveN-compatible magazine and is designed for right-hand users.
