Purchased this at Tucson Arms a month ago. The accuracy was impressive right out of the box – grouped under 2 MOA with Federal ammo. My only nitpick is the trigger feels a bit heavy for precision work, but it’s reliable. Great value for the price.

As a new shooter, I appreciated how easy this was to handle. The adjustable stock fit me perfectly, and the controls were intuitive. Took a class at Ben Avery Shooting Facility and the instructor complimented the rifle’s reliability. Zero issues with 300 rounds so far.

Used this during a 3-gun match in Phoenix last month. The cerakote finish held up perfectly in 100-degree weather. Only reason for 4 stars is the magazine release required more pressure than I’d like during timed stages. Otherwise performed excellently.

Took this DB15 out to the desert near Tucson last weekend. The .223 Wylde chamber handled both .223 and 5.56 ammo perfectly, and I was hitting steel at 200 yards consistently. The lightweight build made it easy to carry during our all-day session.

Put this DB15 through its paces at the range yesterday. Fed everything from cheap steel case to premium brass without a single malfunction. The M-LOK handguard stayed cool even during rapid fire. Balance felt perfect for quick target transitions.

Sighted this in at the Rio Salado Sportsman’s Club range. The 1:8 twist barrel stabilized 62-grain bullets beautifully – my best 5-shot group measured 1.25 inches at 100 yards. The ergonomic grip reduced fatigue during extended shooting sessions. Very pleased with this purchase.
