KelTec KSG 12 Ga Bullpup Pump Action Shotgun - Black

The Kel-Tec KSG is a bullpup pump action shotgun built for shooters who need a compact, high-capacity 12-gauge without sacrificing firepower. At just 26.1 inches overall and weighing 6.9 lbs, the KSG delivers serious capability in a footprint that fits tight spaces—whether you're working through doorways, vehicles, or confined tactical scenarios. The dual-tube magazine system is the real story here: you get a total of 12 rounds of 3-inch magnum ammunition on board (6 per tube), plus 1 in the chamber, and you can switch between left and right tubes via a lever behind the trigger guard. That means you can load different ammunition types—slugs in one tube, buckshot in the other—and select on the fly.

The KSG handles everything from short 1.75-inch shells up to full 3-inch magnums, giving you genuine flexibility at the range or in the field. The hardened steel receiver houses the welded magazine tubes and runs a no-nonsense pump action that's proven reliable. The black synthetic furniture is Zytel glass-reinforced nylon—tough and lightweight—and the stock comes apart easily by pushing out two pins, making cleaning and maintenance straightforward. A soft rubber butt pad helps soak up recoil, and the gun ships with sling loops already integrated front and rear, plus a basic sling included.

From the factory, the KSG arrives outfitted with a top Picatinny rail for optics or iron sights and an under-barrel Picatinny rail for forward grips, lights, or lasers. That modular approach means you can build it out to match your mission without guessing whether accessories will fit. The 18.5-inch cylinder bore barrel keeps the gun compact while maintaining the velocity you need. If you want a pump shotgun that breaks the mold—literally and functionally—the Kel-Tec KSG delivers.

Frequently Asked Questions

Can I load different ammunition types in each tube?

Yes. The KSG features a manual selector lever behind the trigger guard that lets you choose which tube feeds the chamber. This is one of the gun's key advantages—you can load slugs in one tube and buckshot in the other, then select between them as your situation requires.

What size shells does the KSG shoot?

The KSG reliably cycles 1.75-inch, 2.75-inch, and 3-inch magnum shells. This wide compatibility gives you options for hunting, sport shooting, and home defense without needing multiple shotguns.

Is the KSG easy to take apart for cleaning?

Yes. The grip and stock assembly disassembles by pushing out two pins, which store in holes in the grip. The barrel and pump assembly comes off by loosening two nuts on the front magazine tubes with a coin and sliding the assembly forward. No special tools required.

What accessories can I mount on the KSG?

The KSG ships with Picatinny rails on top and underneath the barrel. The top rail accepts any standard optics or iron sights; the under-barrel rail is ready for forward grips, tactical lights, or lasers. The gun also includes integrated sling loops and a basic sling.
