Diamondback
The Diamondback DB15 rifle in 5.56 NATO is a solid mid-range AR platform built on proven components and a clean, professional finish. This 16-inch carbine pairs a forged aluminum upper and lower receiver with a reliable mid-length gas system, making it equally at home on the range, in a defensive role, or as a dependable hunting rifle for varmint and medium game. The Jesse James Blue Cerakote gives it a distinctive look that stands apart from typical black or FDE builds, while the 1/2x28 threaded barrel leaves the door open for suppressors or muzzle devices down the line.
What makes the DB15 approachable is its no-nonsense component selection. You get a forged 7075 T-6 upper receiver in A3 configuration, a mil-spec trigger, and a properly inspected and shot-peened carrier group. The 15-inch M-LOK handguard with anti-slip texture pads gives you plenty of real estate for accessories without forcing you into proprietary ecosystems. Magpul controls—MOE grip, MOE-PR stock, and a 30-round PMAG—round out the package with reliability that shooters trust. At 6.7 pounds unloaded and collapsible to 32.75 inches, it's manageable in tight spaces but still substantial enough for precision work at distance.
This is a rifle for shooters who want quality without hype: clean engineering, solid metallurgy, and a finish that photographs well and handles hard use. Whether you're building a first AR, stocking a truck gun, or looking for a second rifle that won't break the bank, the DB15 delivers the goods. No optics included, so you can choose glass that fits your mission.

The DB15 is chambered in 5.56 NATO, a versatile cartridge suitable for target shooting, varmint hunting, and defensive applications. The 16-inch barrel and mid-length gas system are optimized for this round. Effective range depends on your optic choice, ammunition, and skill, but 5.56 NATO is capable out to several hundred yards.
Yes. The barrel features a 1/2x28 threaded muzzle, which is the standard threading for 5.56 NATO suppressors and accessories. It currently comes with an A2 flash hider, which you can replace with a suppressor, muzzle brake, or other compatible device.
The DB15 ships without sights or an optic, so you'll need to add your own. The A3 flattop upper receiver has a standard Picatinny rail for mounting an optic of your choice—anything from a red dot or magnified scope to traditional iron sights will work.
At 6.7 pounds, it's relatively light for an AR-15, which helps reduce fatigue during longer shooting days. The Magpul MOE grip is ergonomic, the MOE-PR stock is adjustable for length of pull, and the 15-inch M-LOK handguard with anti-slip texture provides a secure hold. The mid-length gas system also tends to produce a smoother shooting experience compared to carbine-length systems.
