The Diamondback DB15 offers a robust and adaptable AR-15 platform, engineered for consistent performance and user-centric customization. This rifle integrates proven material specifications with practical enhancements, providing a reliable option for various operational requirements.
Key Features
Barrel and Gas System
The DB15 utilizes a 16-inch, medium-profile barrel constructed from 4150 Chrome Moly steel. This material selection provides a balance of durability and accuracy potential. A mid-length gas system is employed, which contributes to reduced recoil impulse and optimized cycling compared to carbine-length systems, promoting smoother operation. The gas block is precisely pinned to the barrel, ensuring a secure and reliable gas seal under sustained use.
Receiver Construction
Both the upper and lower receivers are machined from 7075-T6 aluminum, a high-strength aluminum alloy known for its superior fatigue resistance and durability in firearm applications. This material specification ensures a rigid foundation for the rifle’s operating components. The receivers are finished in black hardcoat anodizing, providing corrosion resistance and a non-reflective surface.
Bolt Carrier Group
The bolt carrier is manufactured from Mil-Spec 8620 steel, a common alloy for high-stress components in military-grade firearms. The entire bolt carrier group (BCG) undergoes a shot-peening process, enhancing its surface hardness and mitigating potential stress risers, thereby increasing its overall service life and operational reliability.
Ergonomics and Accessory Integration
The rifle features a 15-inch M-Lok anti-rotation handguard, providing extensive surface area for direct accessory attachment without the added bulk of Picatinny sections. The anti-rotation design ensures the handguard remains securely indexed to the receiver, maintaining zero on mounted optics and aiming devices. Ergonomic enhancements include a Magpul MOE-K2+ grip, offering a steeper grip angle for improved control and a rubber overmold for enhanced purchase. The Magpul ACS-L (Adaptable Carbine Stock – Light) provides a streamlined, adjustable platform with optimized cheek weld and an integral storage compartment.
