The Diamondback DB15 5.56 NATO 7-inch black pistol (brand part no. DB1912K001) is the short-barrel, black hardcoat anodize version of Diamondback’s compact AR pistol. Diamondback Firearms uses a heavy 7-inch barrel with a pistol-length gas system, an M-LOK handguard and a foam pad on the buffer tube. The forged flattop upper and Diamondback Carbon lower keep the weight low. With a Magpul MOE grip and a 30-round PMAG, it is a handy size for a backpack or vehicle.
