What’s Included
- Standard Manufacturing DP-12 12 Gauge pump-action shotgun
The DP-12 pairs two 18.875-inch steel barrels with twin magazine tubes inside a bullpup configuration, delivering a compact overall length of about 29.5 inches. Its unique action fires the right barrel then the left barrel on successive pulls of a single trigger, while loading and ejection occur from the bottom via a single rear port.
Chambered for both 2 3/4-inch and 3-inch 12 Gauge shells, the factory capacity is rated at 7+7+2 with 2 3/4-inch shells or 6+6+2 with 3-inch shells. This design provides substantial on-board capacity without adding external length, and the listed capacity for this example is 15+1.
The shotgun is built with an aluminum alloy receiver and a black polymer frame, stock, and forend. It includes a full-length top Picatinny rail with a lower accessory rail, a pistol grip, and a recoil pad. Safety features include a manual safety, and the length of pull measures 15.0 inches.
The twin barrels use an interchangeable flush choke system and are threaded to accept compatible choke tubes. Unloaded weight is approximately 9.3 pounds, contributing to stable handling. The DP-12 platform was recognized with an NRA Golden Bullseye Award in 2017, underscoring its innovative design.
