After zeroing the sights at the local range, I was hitting 2-inch groups at 75 yards with basic ammunition. The California-compliant features didn’t interfere with handling as much as I’d feared. The rifle balanced well and felt solid during rapid fire drills.

Took this to the outdoor range near Bakersfield last weekend and put 200 rounds through it. The rifle cycled perfectly with different 5.56 loads, but the trigger pull was heavier than I expected. Still, it grouped well at 50 yards once I got used to it.

I was worried about finding a compliant AR-15 in California, but this Diamondback DB15 checked all the boxes. The fixed stock and fin grip felt secure at the range, and the 5.56 chambering handled my bulk ammo without a hiccup. Accuracy was solid at 100 yards with iron sights.

For the price, this DB15 delivers what you need in our state. The 5.56 chamber ate through my mixed brass without issues, though I did notice it preferred certain brands for best accuracy. The fixed magazine system works smoothly once you get the hang of it.
