Diamondback DB15 5.56 NATO 16" Rifle 30rd M-LOK FDE Magpul Grip

The Diamondback DB175AK131 DB15 delivers reliable semi-automatic performance with enhanced ergonomics and modern manufacturing standards. This Sports South exclusive combines proven AR-15 platform reliability with upgraded components that address common shooter concerns about durability and handling comfort.

What Makes This Different

The 7075-T6 aluminum receiver construction provides 40% greater strength than standard 6061 aluminum while maintaining lightweight handling characteristics. Black nitride barrel treatment offers superior corrosion resistance and extends barrel life beyond standard phosphate coatings. The 15-inch M-LOK handguard spans nearly the entire 16-inch barrel length, maximizing accessory mounting options and improving balance compared to carbine-length systems.

Key Features

• 16-inch black nitride treated barrel with 1:7 twist rate for stabilizing heavier projectiles
• 7075-T6 forged aluminum upper and lower receivers with Type III hard coat anodizing
• 15-inch free-floating M-LOK handguard with anti-rotation barrel nut system
• Magpul MOE grip in Flat Dark Earth finish for enhanced texture and ergonomics
• 30-round capacity magazine included with anti-tilt follower design
• Standard AR-15 trigger group compatible with aftermarket upgrades
• Picatinny rail top extends full length for optics and backup iron sights

Field performance centers on the mid-length gas system that reduces felt recoil and improves cycling reliability with various ammunition weights. The nitride barrel treatment maintains accuracy potential through extended firing sessions while resisting fouling buildup. Competition shooters benefit from the extended handguard's stability for bipod mounting, while the platform accommodates both tactical applications and sporting use with appropriate optics selection.
