The Diamondback DB9R 9mm AR rifle delivers affordable, reliable semi-automatic performance in a compact, modern platform. Built on a forged 7075 T-6 aluminum upper and lower receiver with a genuine 16-inch 4150 CrMoV barrel finished in corrosion-resistant black nitride, this 9mm AR is equally at home at the range, in a competition, or as a capable home-defense rifle. At 6.6 pounds, it's nimble enough for extended shooting sessions without sacrificing the handling and ergonomics shooters expect from a modern tactical rifle.
The DB9R comes equipped with a 15-inch M-LOK rail handguard featuring full-length Picatinny sections, QD mounts, and textured grip panels—giving you plenty of real estate to mount optics, lights, or lasers without breaking the bank. The trigger is mil-spec 5-pound, and you get a Magpul MOE grip and collapsible MOE stock (32 inches collapsed, 35.25 inches extended) for customizable fit and control. A 32-round Promag magazine is included, so you'll have capacity without the complexity or cost of magazine conversions.
A black nitride bolt carrier group handles the 9mm cartridge reliably, and the A2-style flash hider (5/8 x 24 thread) keeps muzzle flash manageable in low-light conditions. Whether you're stepping into the AR platform, looking for a dedicated 9mm trainer, or building a second rifle, the DB9R gives you solid construction and proven ergonomics at a straightforward price point.
