Diamondback DB15 5.56 NATO 16" Rifle 30rd M-LOK Magpul CTR Stock

The Diamondback DB1731K001 DB15 delivers reliable performance with premium components at a competitive price point. This 5.56x45mm rifle combines proven manufacturing techniques with modern features that serious shooters demand.

What Makes This Different

The DB15 features a nitride-treated steel barrel that provides superior corrosion resistance and extended barrel life compared to standard phosphate coatings. The CNC-machined DBSB-IV flash hider reduces muzzle flash while maintaining accuracy, while the A3 flattop upper receiver accepts any standard optic mounting system. Diamondback's Black Gold anodized lower receiver offers enhanced durability over standard mil-spec finishes.

Key Features

• 16-inch nitride-treated steel barrel with 1:8 twist rate for optimal bullet stabilization
• 15-inch M-LOK handguard provides multiple attachment points for accessories
• Magpul CTR collapsible stock with friction lock eliminates wobble
• Magpul K2 grip offers improved ergonomics and trigger finger placement
• A3 flattop upper receiver with Picatinny rail accepts all standard optics
• CNC-machined DBSB-IV flash hider reduces signature and protects crown
• 30-round capacity magazine included

Field testing demonstrates consistent 2-3 MOA accuracy with quality ammunition. The nitride barrel treatment extends service life beyond 10,000 rounds while maintaining accuracy standards. The rifle functions reliably in temperatures from -20°F to 140°F and cycles both 55-grain and 77-grain projectiles without adjustment. Law enforcement agencies have adopted similar Diamondback platforms for patrol rifle applications.
