Diamondback's DB10 Rifle Series is an outstanding value proposition when comparing components to price. The DB10 features a mid-length gas system with a melonite AR10 carrier with multi-caliber bolt, DPMS-style barrel extension, and high pressure firing pin. This Elite model has an Adaptive Tactical EX Performance stock, A2-style pistol grip and a free-floated, nitrided barrel with a muzzle brake. It also has a FDE 7075-T6 forged aluminum receiver and 15" M-Lok handguard.
