Diamondback DB175AB002 300 Blackout 16" Rifle 30+1 Carbon Fiber Stock

The Diamondback DB15 delivers proven AR-15 platform reliability in the versatile 300 AAC Blackout chambering, combining suppressor-ready performance with modern tactical features. This rifle bridges the gap between close-quarters effectiveness and extended-range capability through its optimized barrel length and advanced handguard system.

What Makes This Different

The DB15 features a 16-inch black nitride barrel that maximizes 300 Blackout ballistic potential while maintaining compact handling characteristics. The 15-inch M-LOK handguard extends nearly to the muzzle, providing exceptional accessory mounting real estate compared to standard carbine-length systems. Black hardcoat anodized receivers meet mil-spec tolerances for consistent lockup and enhanced corrosion resistance.

Key Features

• 300 AAC Blackout chambering optimized for both subsonic and supersonic ammunition
• 16-inch black nitride barrel with 1:7 twist rate for heavy bullet stabilization
• 15-inch M-LOK handguard with full-length top rail for optics and accessories
• Carbon fiber buttstock reduces weight while maintaining structural integrity
• Magpul MOE grip provides ergonomic control and storage compartment
• Picatinny rail system accepts standard AR-15 accessories and optics
• 30-round magazine capacity with STANAG compatibility

The 300 Blackout cartridge excels in tactical applications where versatility matters most. Supersonic loads deliver rifle-level performance out to 300 yards, while subsonic ammunition runs quietly through suppressors for close-range work. The 16-inch barrel length ensures full powder burn for maximum velocity while remaining handy in confined spaces. Weather-resistant finishes protect critical components during extended field use.
