Diamondback DB15 300 Blackout Pistol 10" Barrel 28+1 Carbon Lower

The Diamondback DB15 300 Blackout pistol delivers subsonic and supersonic versatility in a compact platform engineered for close-quarters effectiveness. This AR-style pistol combines proven direct impingement operation with modern manufacturing techniques to create a reliable firearm suitable for multiple applications.

What Makes This Different

The carbon fiber lower receiver reduces overall weight while maintaining structural integrity under repeated firing cycles. Unlike standard aluminum lowers, this carbon construction absorbs vibration more effectively and resists corrosion in harsh environments. The 9-inch M-LOK handguard provides ample accessory mounting space while keeping the overall length manageable for vehicle operations or confined spaces.

Key Features

• 10-inch barrel optimized for 300 Blackout ballistics with proper powder burn
• Carbon fiber lower receiver weighs 30% less than standard aluminum
• 9-inch M-LOK handguard with continuous Picatinny top rail
• Magpul MOE grip provides consistent hand placement and texture
• Padded buffer tube reduces felt recoil and protects against impact
• 28+1 capacity with standard AR-15 magazine compatibility
• Matte black finish resists wear and reduces glare

The 300 Blackout cartridge performs exceptionally well from shorter barrels, making this 10-inch configuration ideal for suppressed shooting or situations requiring reduced blast signature. The platform accepts standard AR-15 triggers, charging handles, and bolt carrier groups, ensuring parts availability and customization options. Weather-resistant construction handles temperature extremes and moisture exposure typical in tactical environments.
