Used this at the Rio Salado range three times now. The 5.56 chamber handled both brass and steel case ammo without jams. Recoil was manageable, and the quad rail stayed secure even after mounting a foregrip. Solid purchase for Arizona shooters.

The DB15 performed well at the range, and the quad rail gave me plenty of mounting options. My only nitpick is the trigger felt a bit heavy compared to my other AR-15. Still a reliable rifle for the price.

The rifle shot accurately with most .223 loads I tried. However, it didn’t like one brand of cheaper steel case—had a couple of failures to eject. Otherwise, the quad rail is sturdy, and it feels well-built. Would recommend for the price.

Took it coyote hunting in the Arizona backcountry. The lightweight design made it easy to carry, and the quad rail held my scope mount tightly. Shot a 5.56 round cleanly at 150 yards. No malfunctions despite dusty conditions.
Diego M. (verified owner) –
Took this out to the desert near Tucson and put 200 rounds through it. The 5.56 ammo cycled flawlessly, and the quad rail felt solid when I mounted my light. Accuracy was impressive at 100 yards.

Zeroed it at 50 yards with Federal .223 ammo and was hitting consistent groups. The rifle balanced well, and the quad rail made attaching accessories straightforward. Tucson Arms had it ready for pickup quickly.
