At $620.99, it presents performance-oriented components at an accessible price point. Shop this product to view current availability and specifications.

Barrel, Muzzle, and Accuracy

The 16″ Black Nitride threaded barrel offers corrosion resistance and easier cleaning intervals compared with untreated barrels. Threading allows suppressor or muzzle device swaps; the included A2 flash hider is a rugged, proven option. Chambered in 5.56 NATO, this rifle benefits from abundant ammunition choices, flatter trajectories at typical engagement distances, and controllable recoil for fast, repeatable follow-ups.

Rail System and Controls

The 15″ M-LOK rail with texture pads gives ample space for lights, grips, and backup sights while keeping weight down. A Picatinny rail on the upper provides zeroed optic mounting, and front and rear QD points plus an integrated hand stop enhance one-handed manipulation and accessory attachment. The Magpul MOE grip and adjustable black synthetic stock round out an ergonomically user-friendly control package.

Use Case and Tactical Value

As a Semi Auto platform, the DB15 is well suited for marksmanship training, service-style drills, and defensive drills that rely on fast, accurate shots with low recoil. The combination of a forged 7075 T-6 upper and carbon lower improves durability under regular cycling while keeping the rifle responsive for competition or duty use. For those prioritizing modularity, the M-LOK rail and threaded barrel make future upgrades straightforward. View product details and pricing.
