Engineered Performance & Compliance
The Diamondback DB15 .300 Blackout rifle is engineered for shooters requiring a compliant AR platform without compromising performance. This model integrates the Thorsden Featureless GenII FRS-15 stock and a 10-round magazine, ensuring adherence to state regulations while maintaining a functional operational profile. The .300 Blackout chambering provides inherent versatility across a broad spectrum of applications.
Construction & Precision Engineering
Core Build Integrity
- Manufactured in the USA, the DB15 utilizes high-quality CNC machined components, establishing a robust foundation.
- The rifle is constructed upon a forged 7075 T6 aluminum lower receiver and a forged A3 flattop upper receiver, ensuring structural integrity and durability under operational stress.
Barrel & System Reliability
- A 16-inch, melonite-coated 4140 chrome-moly barrel is free-floated, mitigating external barrel contact for consistent harmonic performance and contributing to repeatable shot placement.
- The gas-impingement system is precisely engineered for dependable cycling and operational consistency.
Operational Integration & Application
Accessory & Optic Interface
The 12-inch M-LOK handguard provides extensive interface capacity for direct mounting of essential firearm accessories, including bipods and weapon lights, optimizing operational configuration. Without integrated iron sights, the A3 flattop upper readily accepts diverse tactical optics, facilitating enhanced target acquisition and engagement precision.
Caliber Versatility & Practical Utility
The .300 Blackout chambering offers substantial versatility across varied bullet weights, accommodating both short-range engagements and specific hunting applications. This platform is suitable for consistent practice at the shooting range, effective pest control, and as a component of a personal defense strategy. Consistent application of appropriate gun cleaning supplies is essential to maintain long-term reliability and preserve system longevity.
