Standard Manufacturing DP-12 Bullpup 12 Gauge Pump Shotgun, 14+2 Capacity, 18.875" Twin Barrels
The Standard Manufacturing DP-12 is a patented, U.S.-made bullpup shotgun that delivers two 18.875-inch chrome-lined barrels, twin magazine tubes, and a 14+2 payload in a compact, full-size platform. Recognized with the 2017 Shooting Illustrated Golden Bullseye Shotgun of the Year award, this dual-barrel pump combines downward loading and ejection with a single-trigger system for rapid, reliable follow-up shots. A 34-slot Picatinny top rail, accessory rail, and Tru-Choke threaded cylinders make it ready for optics and muzzle devices right out of the box.

What’s Included
- Standard Manufacturing DP-12 owner’s manual
This DP-12 features a bullpup layout that positions both 18.875-inch barrels and dual 7-round magazine tubes behind the trigger, keeping overall length short while preserving a 14+2 capacity with standard 2 ¾-inch shells—3-inch shells are also supported.
The shotgun uses a single, centrally located trigger: pump once, pull once for the right barrel; pull again for the left. An ambidextrous safety selector sits above the grip for intuitive use by right- or left-handed shooters.
Constructed around a 7075-T6 aluminum receiver mated to a polymer/aluminum hybrid chassis, the DP-12 wears a matte black finish throughout. The polymer stock integrates a textured pistol grip, rubber recoil pad, sling-swivel cup, and a 14.5-inch length of pull.
Both barrels are chrome-lined and Tru-Choke threaded with cylinder chokes installed, giving buyers an easy path to muzzle devices or alternative choke tubes. An optic-ready 34-slot Picatinny rail spans the top of the receiver and handguard, while a second rail beneath the forend accommodates lights or lasers.
