Overview
Double-barrel pump shotgun firing two rounds per pump stroke with a single trigger, inline feeding, ambidextrous controls, and M-Lok/Picatinny rails in a flat dark earth tactical package.
Available for delivery across the United States.
The standard manufacturing dp-12 gen ii 12 gauge pump shotgun is a double-barrel pump-action that fires two shots per pump stroke from a single trigger, giving you rapid follow-up capability without losing the manual-action reliability. Built with inline feeding and ambidextrous controls, it delivers 12-gauge firepower in a flat dark earth package with a synthetic tactical stock and rubber recoil pad. This is a specialized defensive tool, not a field gun.
Two Shots Per Pump – Inline feeding from twin magazines lets you fire two rounds with one pump cycle, cutting your split times in half compared to a standard pump gun.
Single Trigger with Sequential Fire – One trigger pull fires the right barrel, the next fires the left, giving you a controlled two-round burst without a selector switch.
Ambidextrous Controls – Safety and bolt release are mirrored for left- and right-handed shooters, so you don’t have to retrain muscle memory.
Integrated M-Lok and Picatinny Rails – Mount a light, laser, or red dot directly to the forend and receiver without aftermarket adapters.
Rubber Recoil Pad – The factory pad reduces felt recoil from rapid follow-up shots, keeping you on target through extended strings.
Who It’s For
This shotgun is built for shooters who want maximum capacity and fast follow-up in a pump platform—home defenders, competition shooters in tactical shotgun divisions, and collectors of unique firearms. It is not a hunting or clay gun; the weight and twin-barrel design are optimized for close-quarters use.

FAQ
What shells does the DP-12 Gen II accept?
It cycles 12-gauge 2.75-inch and 3-inch shells. Stick to high-brass loads for reliability during break-in—low-recoil target loads may not always cycle the pump smoothly.
Can I mount an optic without a gunsmith?
Yes. The receiver top has a Picatinny rail, and the forend has M-Lok slots. You can attach a red dot, light, or laser with standard mounts in minutes.
Is the DP-12 legal in my state?
Check local laws on barrel length and capacity. The DP-12 has an 18.5-inch barrel and a 14+2 capacity, which may be restricted in some states and municipalities.
How does the single trigger work with two barrels?
It fires the right barrel first, then the left on the next trigger pull. The trigger resets after each shot, and you pump to reload both chambers.
