Description
Few shotguns turn heads at the counter like the Kel-Tec KSG, and this OD Green version is one of the harder ones to track down. The bullpup layout puts the action behind the trigger, so you get a full 18.5 inch cylinder bore barrel in a package that measures just 26.1 inches overall and weighs 6.9 pounds empty. That is shorter than most tactical pumps by a wide margin, and you feel the difference the second you shoulder it in a hallway or truck cab.
Dual Tubes Are What Make the KSG Special
The headline feature is the pair of magazine tubes running under the barrel. Each holds six 3 inch shells or seven 2.75 inch shells, giving you 12+1 or 14+1 total depending on what you feed it. A selector lever behind the trigger guard picks which tube feeds, so you can run buckshot in one and slugs in the other and swap on the fly. Set the lever in the center detent and you can cycle the action to clear the chamber without feeding a fresh round. Spent hulls drop straight down out of the bottom, which means lefties and righties get the same experience with no brass flying past their face.
Built Like Kel-Tec Means It
The receiver is hardened steel with the magazine tubes welded in place, while the grip and stock assembly is glass reinforced Zytel that keeps weight down. Takedown is quick, just push out two pins that store in holes in the grip so you do not lose them. A soft rubber butt pad takes the edge off 12 gauge recoil, which matters on a gun this light.
Setting Up Your KSG OD Green
There are no sights out of the box, and that is by design. The full length top Picatinny rail is ready for a red dot or flip up irons, and the rail under the pump handles a light or vertical grip. Sling loops are built in front and rear, and a basic sling ships with it. For home defense duty or just a fun range gun that draws a crowd, the KSG remains one of a kind.

Frequently Asked Questions
How many rounds does the Kel-Tec KSG hold?
The KSG uses two internal magazine tubes. Each tube holds six 3 inch shells or seven 2.75 inch shells, so total capacity is 12+1 with 3 inch loads or 14+1 with standard 2.75 inch shells. A lever behind the trigger guard selects which tube feeds the action.
Does the KSG OD Green come with sights?
No, it ships without sights. Kel-Tec includes a full length top Picatinny rail so you can mount whatever suits you, whether that is a red dot, flip up irons, or a low power optic. There is also a rail under the pump for a light, laser, or vertical grip.
Is the Kel-Tec KSG good for left-handed use?
Yes, and it is one of the best pump guns out there for lefties. Spent shells eject straight down out of the bottom of the receiver instead of flying out the side, so it runs the same from either shoulder. The cross-bolt safety and pump release are also easy to reach from both sides.
Can I run slugs and buckshot at the same time in the KSG?
You can, and this is one of the platform's biggest selling points. Load slugs in one tube and buckshot in the other, then flip the selector lever to switch between them on the fly. The cylinder bore barrel handles both just fine at practical defensive distances.
