The Diamondback Firearms DB15 in .223 Remington and 5.56 NATO has a 16-inch threaded barrel, a 15-inch M-LOK free-float handguard and a flat-top upper with a Picatinny optics rail. It uses a semi-automatic direct-impingement system, comes with a Cerakote American Flag Pattern finish, and feeds from 30-round detachable magazines, with one magazine included. The rifle is optic ready and has a manual safety.

This is an AR-pattern configuration for shooters who want an optic-ready rifle with a free-float handguard for mounting accessories. The American Flag Pattern finish is the distinctive look the supplier describes, and the flat-top upper keeps optic mounting simple. The 16-inch barrel is the length listed for this configuration. The threaded muzzle takes compatible muzzle devices, and the 30-round capacity suits longer range sessions without frequent reloads.
