Availability: In Stock
The Diamondback DB15 5.56 pistol is a compact, semi-automatic AR-platform firearm built for shooters who want the ergonomics and modularity of the AR pattern in a short-barreled package. With its 10-inch 4150 CrMov barrel, carbine-length gas system, and 26–28.5-inch overall length, this is a serious choice for close-quarters training, home defense, or tactical use. It arrives with a 30-round Gen 2 PMAG and an SBA3 stabilizing brace, ready to run.
The DB15 starts with solid fundamentals: a forged 7075 T-6 aluminum upper and lower receiver, both a hallmark of good AR builds, paired with a mil-spec 8620 bolt carrier group that's been shot-peened and magnetic particle inspected. That attention to internal quality means reliability you can count on when it matters. The A3 flattop upper gives you true Picatinny real estate for mounting optics, and the 9-inch M-LOK handguard is modular enough for lights, lasers, or fore-grip attachment.
The 10-inch barrel sports a black nitride finish with an A2 flash hider—practical details that reduce flash signature and keep the gun running clean. Standard trigger, MOE pistol grip, and that SBA3 brace round out a config that's field-proven and easy to customize. No sights come installed, so you're free to pick glass or irons that match your mission. At just 5.7 pounds, this pistol-length AR is light enough for extended handling without feeling under-built.
If you shoot ARs and want to add a nimble, serious 5.56 firearm to your safe—whether for home defense, SBR potential, or precision pistol work—the Diamondback DB15 delivers mil-spec bones and honest construction without pretense.
