Diamondback DB15 Pistol | 5.56 NATO | 10in | DB1915K001

The Diamondback DB15 is an AR-style pistol chambered in .223 Rem / 5.56 NATO with a 10-inch 4150 Chrome-Moly Vanadium barrel finished in black nitride. It features a 9-inch M-LOK free-float handguard, forged 7075-T6 aluminum upper and lower receivers, a Magpul MOE grip and ships with a single 30-round Magpul PMAG. For a versatile optic under $1000 that pairs well with this platform, consider a Vortex Strike Eagle 1-8×24 for fast target acquisition at close ranges and controllable precision at extended distances.

Typical applications for this AR pistol include deliberate range training and practical/tactical competition where compact handling and modular accessory mounting are priorities.
