Selling my DP-12 needing the extra cash. It shoots 2" 3/4' or 3" shells. Did fire birdshot, buckshot and slugs from it. Very fun to shoot. Fired around 150 rounds. When shooting itll shot twice before needing to pump it. Holds 7 rounds in each tube and 1 each in both chambers. The picture with the O ring is there cause it did have a pin for that area but lost it when shooting it. Still works good and doesnt have a problem. Must have a valid Drivers License, be a ND resident and do a Bill-of-Sale at time of purchase. Texting my number works best since don't get notifications on here. (701) 278-0935
