The Diamondback DB15 is engineered as a robust and adaptable AR-15 platform, designed for consistent performance across diverse operational demands. Manufactured entirely in the USA, this rifle integrates durable components to ensure reliable function for competitive shooting, training, and general utility applications.
Construction & Materials
Barrel System
The 16-inch 4150 Chrome Moly Vanadium barrel is specified for consistent projectile velocity and reliable gas operation. It is integrated with a carbine-length gas system, optimized for predictable cycling and recoil impulse across varied ammunition types. A standard A2 flash hider is factory-installed to mitigate muzzle flash signature.
Bolt Carrier Group
The Mil-Spec 8620 steel bolt carrier group undergoes shot-peening and Magnetic Particle Inspection (MPI) to verify material integrity and structural durability, ensuring sustained function under rigorous operational cycles.
Receiver Assembly
The upper receiver is a forged 7075 T-6 aluminum A3 flattop, featuring T-Markings for precise optic and accessory relocation. It provides a stable interface for tactical optics. The lower receiver, constructed from DB-15 Carbon material, contributes to a balanced, lightweight foundation while maintaining structural rigidity.
Ergonomics & Integration
Handguard & Accessory Interface
A 15-inch Magpul MOE M-Lok AV handguard provides substantial rail estate for accessory integration. Its textured pads enhance user interface, while the M-Lok system facilitates direct attachment of tactical lights, lasers, and other mission-essential equipment. The full-length Picatinny rail on the upper receiver ensures consistent optic mounting.
Furniture & Controls
User contact points are optimized with Magpul MOE furniture, including a robust Magpul MOE pistol grip and a Magpul MOE carbine stock. Integrated front and rear QD sling points enable rapid sling attachment and detachment, while a hand stop provides enhanced control and repeatable grip indexing. The rifle incorporates a Mil-Spec trigger unit, offering a familiar and consistent pull characteristic.
Caliber & Capacity
Chambered for 5.56x45mm NATO, the DB15 also reliably cycles .223 Remington ammunition. Each rifle ships with one Magpul Gen M2 PMAG 30-round magazine, ensuring immediate operational readiness.
