The KSG’s bullpup layout places the action behind the trigger to keep overall length short while maintaining an 18.5 inch barrel. Bottom loading and ejection streamline operation from either shoulder. Dual under-barrel magazine tubes support a combined capacity of 14+1 with 2.75 inch shells, offering substantial onboard payload without external magazines.
This shotgun is configured with a 3 inch chamber and a cylinder bore choke, making it compatible with 2.75 inch and 3 inch 12 gauge loads. The smoothbore steel barrel and cylinder bore provide consistent shot patterns appropriate for a wide range of shell types within that configuration.
Controls and furniture are practical and durable: a cross-bolt safety, a textured polymer fore-end, and a textured polymer pistol grip with the Kel-Tec waffle pattern. The fixed buttpad and a 13 inch length of pull contribute to the KSG’s compact handling characteristics.
Rail space is generous, with a full-length top Picatinny rail for mounting compatible sights and an accessory rail under the fore-end. This example includes a Mission First Tactical vertical foregrip installed on the lower rail for enhanced purchase during cycling, and a non-factory two-port muzzle brake/compensator fitted at the muzzle.
Manufactured by Kel-Tec CNC Industries in Cocoa, Florida, USA, the KSG combines a rugged polymer stock system with a steel barrel and a pump-action mechanism. Its bullpup configuration with dual tubes, bottom loading/ejection, and 3 inch chamber define a feature set that is distinctive in the tactical shotgun space.
