After putting about 200 rounds through this at the range, I can say the accuracy surprised me. Groupings were tight at 50 yards with both supers and subs. The rifle balanced well and felt comfortable to shoulder. Cal Guns Depot had it ready to go with all the California-required features already installed.

The DB15 functioned reliably during my range session at the local outdoor range. I liked how the 300 Blackout performed in this platform, especially with subsonic loads. My only nitpick is the trigger – it’s a bit heavier than I prefer for precision shooting. Still, it’s a solid California-compliant option.

The fit and finish on this Diamondback exceeded my expectations. I took it to the range near Sacramento and ran several different 300 Blackout loads through it without any malfunctions. My minor complaint is that it’s a bit picky with some budget ammunition brands. Overall though, it’s a reliable California-compliant rifle that does what it should.

I picked this up from Cal Guns Depot and was impressed with how well it handled the 300 Blackout rounds. The fixed magazine setup works smoothly, and I appreciated not having to worry about California regulations. Took it to the range last weekend and had no issues with feeding or ejection. Accuracy was solid at 100 yards with the iron sights.
