I’ve had this for about six weeks now and the finish shows no wear despite regular use. The 5.56mm chambering gives me flexibility with ammunition choices, and the pistol balances nicely with the brace installed. It’s become my go-to for range days here in the Irving area.

After testing several AR pistols, I settled on this one from Dallas Shooters Supply. The 5.56mm chambering gives me plenty of options for ammo, and the overall build quality feels solid. My only nitpick is the trigger pull – it’s a bit heavier than I prefer for precision shooting, but that’s easily fixable with an aftermarket upgrade.

I purchased this from Dallas Shooters Supply last month. The build quality is excellent and the flat dark earth color looks sharp. My only issue has been with some cheaper steel-case ammo – it occasionally fails to feed properly. With quality brass, it runs perfectly. Still a great value for the money.

I used this during a tactical training course last weekend and it performed admirably. The compact size with the brace made moving through obstacles easy, and the 5.56mm had plenty of stopping power for the steel targets. After running 300 rounds in dusty conditions, I didn’t experience a single malfunction.

I took this to the range in Fort Worth last weekend and was impressed with the accuracy right out of the box. The 5.56mm round performed flawlessly through 200 rounds, and the flat dark earth finish looks even better in person. The Maxim brace makes it easy to handle in tight spaces, which is perfect for my home here in Texas.

I put this through its paces at my local range over three sessions. The Diamondback DB15 ate everything I fed it – steel case, brass, you name it. The Maxim CQB brace made shooting comfortable even during extended sessions. For a Texas-made firearm available right here in Arlington, it exceeded my expectations.
