Design

The DP-12 shotgun is a manually operated, pump action weapon. The first trigger pull fires the right barrel and the second fires the left.^[2] The sliding forend is connected to the bolt by dual operating bars. Ammunition is fed from 2x independent magazine tubes, located below the barrels.

Rounds are loaded into the magazines through a large loading/ejection port, located at the bottom rear of the gun in the stock, behind the pistol grip. Empty shells are ejected down through the same port. The safety is an ambidextrous AR style lever located above the grip.

Sighting equipment is not included, but iron sights and/or a red dot sight can be installed using the standard Picatinny rail located above the barrels. A second Picatinny rail at the end of the slide (under the muzzles) can be used for a forward grip or other accessories.

Chokes

The barrels come threaded with a Tru-Choke thread pattern and 2x flush-mount spreader choke tubes. There are 2x optional chokes from the manufacturer, the doorbuster tactical choke and stiletto choke.^[3]

Colors

There are several different color variants of this shotgun. They include black, flat-dark earth, green, tan, gold and black & gold two-tone.
