Operating on a direct impingement system, the DB15 offers smooth and reliable action, making it suitable for a wide range of shooting activities, from tactical training and home defense to competitive shooting. The rifle comes with a 30+1 capacity, ensuring ample firepower for any scenario. Its overall length is adjustable between 32.75″ to 36″, allowing shooters to customize the fit to their preference.
The DB15 is equipped with a 16″ chrome moly barrel that features a 1:8″ twist rate, optimized for accuracy with a broad range of bullet weights.

Additionally, the flash hider on a 1/2″-28 thread pattern not only reduces muzzle flash but also allows for the attachment of suppressors or other muzzle devices.
