The KSG SBS is a bullpup, pump-action 12 gauge shotgun with a 13.7-inch steel barrel and a 3-inch chamber. Its dual under-barrel magazine tubes, managed by a manual selector, deliver a maximum capacity of 10+1.
Feeding and ejection are configured for bottom loading and downward ejection, keeping the design compact and user-friendly. A full-length T-marked Picatinny top rail (T2-T18) is installed, and no sights are included.
The exterior pairs a polymer frame and receiver with a two-tone finish: a black lower and a gray/OD upper shroud. The black polymer stock includes a rubber recoil pad, and the pistol grip uses Kel-Tec’s square texturing. Length of pull is 13.0 inches.
This shotgun includes practical additions: a vertical foregrip on the pump fore-end and a compact auxiliary weapon light mounted at the front underside. The setup maintains the KSG’s streamlined profile while adding front-end control and illumination capability.
