Diamondback Firearms DB15 5.56 NATO Pistol, 10″ Barrel, 30+1-Round

Product Description

The Diamondback Firearms DB15 is a semi-auto AR pistol chambered in 5.56 NATO, built around a 10″ 4150 Chrome Moly barrel. It holds 30+1 rounds and runs on a direct impingement system with a pistol-length gas system.

The frame is forged 7075 T6 aluminum, finished in OD Green Cerakote. A 9″ M-LOK rail covers the front end, so you can mount lights, grips and other M-LOK accessories where you want them. The top has an integral Picatinny mount at 0 MOA. The barrel is threaded and carries an A2 flash hider, which gives you a starting point if you want to try a different muzzle device.

Setup and gear

This pistol has no sights. Plan on adding an optic or a set of sights before you take it to the range. The Picatinny top makes that simple. An SBA3 brace sits at the rear, and the grip is A2 style in black plastic. A manual safety is fitted. One metal AR-style magazine is included.

It fits a shooter who likes the AR layout in a shorter, handier format. Good companions are a red dot or other optic, a sling, a weapon light on the M-LOK rail, and extra 30-round AR magazines for longer sessions.
