dp-12 instruction manual

It is an extremely efficient, reliable Bull Pup 16 shot (7 - 2 ¾” shells in each magazine and 1 in each chamber). The DP-12 is a 2 barrel double pump shotgun that is a unique construction, which is protected by US and Foreign patents.

Like a normal pump shotgun, it operates with a single trigger. You need to pull the trigger for each shot. The 1st pull fires the right barrel and the 2nd pull fires the left barrel. It is pumped to reload.

Each gun comes with 2 choke tubes installed in the barrels (please check to make sure they are installed when the gun is empty and the gun is in the open bolt, pulled back position). You will see threads if the tube is not installed, approximately 2 ½” from the muzzle.

The receiver is made from a solid block of forged 775 pre-hardened aluminum billet.  This is a gun made to last in severe conditions. We found that making it from castings or the gun operating on plastic with or without a metal shroud, will not withstand the rigors of heavy use. The barrels are machined from 4140 steel and all shrouds are glass reinforced nylon. All the interior parts are made from steel or aluminum that we have designed and spec’d out for longevity, weight and reliability. 

That brings you to the complete manual and troubleshooting page, as well as specs for the gun. It can be accessed with your smartphone.

Yes, it has provisions for slings. There is a front strap housing to accept a 1” sling and the rear has multiple sling swivel attachments.

This gun is completely ambidextrous. It loads and ejects from the bottom and it has a safety button on each side of the frame.

 It has a large safety button on each side, right and left, on the frame.

Yes, it will reduce the capacity of shells. As for shorter shells... Yes, it will depend on the shell. You would need to check that specific shell for operation. 

 Yes, we are also selling the optional door breeching tubes through our company. 

 It is much more reliable. Unlike a brass rifle case shell, shotgun shells have many imperfections and anomalies. The pump operation offers a lot of flexibility to shoot, eject or remove any out of spec shells.

The DP-12 weighs 9 1/2 lbs. Overall length is 29 1/2"  and the barrel is 18 3/4". 

Some slugs may not truly be 2 3/4". Depending on what ammo you are using, you may not be able to get 7 shells in, due to crimping and styles of manufacturing.

After firing one round, you will not be able to put the safety on. You will have to eject the one loaded shell and one live shell, re-racking the gun or fire the second shell to engage the safety again after re-racking the gun (re-loading). That is the design of the gun.

We believe this gun, in it's current configuration, is legal in all states. We had an ATF consultant research the legality of the DP-12 in states that were questionable and he provided us letters stating the compliance within those states. These states include CT, NJ, NY, CA and MD. Attached bellow are the letters of compliance.
