Florida-based Diamondback Firearms this week announced it is expanding the DBX 57 large format pistol line to include a model in dark grey.
Introduced early last year, the DBX uses an adjustable dual gas piston action with a stainless steel 8-inch threaded barrel that ends in the company's DBX series muzzle device. Using receivers crafted from 7075 aluminum and an M-LOK-compatible 6061 aluminum handguard, the gun is light, coming in at the 3-pound mark right out of the box. Overall length, sans any accessories, is 15.25 inches with a height of 7.3 inches.
