The Diamondback Firearms DB15 6.5 Gren is a semi-auto AR-style rifle with an 18″ barrel. The barrel is 4150 chrome moly with a 1:8″ twist. It runs on a direct impingement system with a mid-length gas system, and the overall length is 38″.
This rifle has no sights, so you will need to add your own. The A3 flattop upper gives you a place to mount an optic. The 15 inch MLOK rail lets you add a sling mount, light, or other accessories. A Mil-Spec trigger and a manual safety handle the controls.
Stock, finish, and muzzle
The stock is a Magpul CTR with MOE K2 grip, and anti-slip texture pads help you keep hold of the rifle. The finish is black anodized hard coat. The barrel is threaded 5/8×24 and wears a DB CNC flash hider, so you can swap in another muzzle device if you want one. Capacity is 5+1 rounds, and the rifle uses metal AR-style magazines.
The DB15 in 6.5 Gren fits shooters who want an AR-platform rifle in a different caliber from the usual choices. It works for range sessions and for hunting-style setups once you add glass. Good pairings include a rifle optic and mount, a sling, extra magazines, 6.5 Gren ammunition, a cleaning kit, and a hard case for transport.
