The Diamondback DB15 AR-15 rifle delivers a robust and adaptable platform, engineered for consistent performance across general utility, sporting, and personal defense applications. Manufactured entirely within the USA, this rifle utilizes the established direct gas impingement operating system, recognized for its operational reliability.
Key Features
Caliber and Barrel Configuration
Chambered in 5.56 NATO, the DB15 ensures full compatibility with both 5.56x45mm and .223 Remington ammunition. Its 16-inch 4150 CrMoV steel barrel, typically featuring a 1:8 right-hand twist, provides a balanced interface between ballistic performance and maneuverability, optimizing projectile stabilization across a range of bullet weights.
M-LOK Free-Float Handguard
An integrated M-LOK free-float handguard minimizes barrel harmonics interference from accessory mounting, enhancing shot consistency. This system provides secure, modular attachment points for essential accessories such as illumination devices, aiming lasers, and vertical grips. A full-length Picatinny top rail extends the optic mounting surface, accommodating various primary and secondary optical systems.
Precision Machined Construction
All critical components are precision-machined in Diamondback’s USA-based CNC facility, ensuring strict dimensional tolerances, optimized component fitment, and enduring operational reliability. The rifle incorporates standard AR-15 control interfaces, facilitating intuitive manipulation for experienced users.
