The Diamondback DB15 5.56 NATO rifle is a no-nonsense AR-15 built around practicality and reliability. With a 16-inch barrel and mid-length gas system, it strikes a proven balance between velocity, handling, and ergonomics—ideal for hunters, sport shooters, and those looking for a capable modern rifle without the frills. The flat dark earth (FDE) Cerakote finish pairs function with a clean, purpose-built aesthetic that works in field or range.
This is a rifle assembled from quality components throughout. The forged 7075 T-6 aluminum upper and lower receiver are paired with a Diamondback Barrels 16-inch 4150 CrMoV barrel (1:8 twist, 1/2 x 28 threads) finished in black nitride. The bolt carrier group is Mil-Spec 8620 steel with shot-peening and magnetic particle inspection—the kind of detail that matters when reliability counts. MagPul furniture—CTR stock, MOE K2 grip, and enhanced trigger guard—provides ergonomic comfort and modularity. The 15-inch M-LOK handguard gives you full Picatinny rail coverage plus QD mounts for slings and accessories, and the ambidextrous controls (charging handle, safety, mag catch) work for shooters of any shoulder.
Out of the box, the DB15 ships with a MagPul Gen M3 PMAG 30-round magazine, a Breek Arms Warhammer Mod2 ambidextrous charging handle, Battle Arms Development enhanced bolt catch and safety selector, and a Diamondback Obsidian muzzle brake. At 6.6 pounds with the stock extended, it's lightweight enough for all-day carry while staying controllable. The rifle has no iron sights, leaving you free to mount optics of your choice on the A3 flat-top upper.
Whether you're zeroing for hunting season, running drills at the range, or building a reliable home-defense carbine, the DB15 delivers proven AR-15 performance with thoughtful component selection and practical ergonomics.

Yes. The rifle includes an ambidextrous charging handle (Breek Arms Warhammer Mod2), ambidextrous safety selector (Battle Arms Development), and ambidextrous magazine catch/release (Battle Arms Development), making it equally functional for left- or right-handed shooters.
The DB15 comes with one MagPul Gen M3 PMAG 30-round magazine. It is a standard AR-15 rifle, so it accepts any standard 5.56 NATO or .223 Remington AR-pattern magazines.
The Diamondball Obsidian muzzle brake is threaded 1/2 x 28, allowing you to remove it or swap it for another muzzle device of the same thread pitch if needed.
The 16-inch barrel with mid-length gas system is a proven, versatile setup: compact enough for home defense or hunting in woods or brush, but long enough to deliver solid velocity and accuracy at typical hunting and sport-shooting distances. It balances maneuverability, sight radius, and ballistics.
