The Kel-Tec KSG is a bullpup 12-gauge pump action shotgun designed by Kel-Tec, a firearms manufacturer based in Cocoa, Florida. It was manufactured since 2011.
This bullpup pump-action shotgun has dual tube magazines that can hold a total of 14+1 rounds of ammunition. These two tube magazines which the user can switch between manually. Each tube holds a total of seven 2.75-inch (70 mm) 12-gauge or six 3-inch (76 mm) shotgun shells.
This unusual-looking shotgun has a total length of 26 inches and a barrel length of 18.5 inches, thus ensuring it does pass any NFA (National Firearms Act) regulations and is allowed for civilians. It comes fully equipped with a picatinny rail with flip sights and a pistol grip.
This shotgun has been compared to the South African NEOSTEAD 2000 Bullpup Shotgun. The main difference is that the NEOSTEAD could be set to feed alternating between both the magazines. The KSG can only set to feed from the right or the left. Once the tube magazine is empty, the operator must use a manual switch to select the other tube magazine. This may appear to be an inconvenient disadvantage but for many people who live in places where shotgun magazine capacity is limited by the law, this feature, or lack of it, could allow them to legally possess the Kel-Tec KSG.
