The Kel-Tec KSG is a pump-action shotgun manufactured by Kel-Tec CNC Industries. It is designed to be compact and offers a high-capacity magazine. Here are some key features and specifications of the Kel-Tec KSG:

1. Gauge: The KSG is chambered for 12 gauge shotgun shells, which is a versatile and widely available shotgun cartridge.
2. Design and Construction: The KSG features a bullpup design, with the action and magazine located behind the pistol grip and trigger assembly. This design allows for a shorter overall length while retaining a full-length barrel. It typically has a polymer stock and a metal receiver.
3. Barrel Length: The KSG is equipped with a 18.5-inch barrel, which strikes a balance between maneuverability and ballistic performance.
4. Magazine Capacity: The most distinctive feature of the KSG is its dual-tube magazine system. It has two separate magazine tubes located below the barrel, each capable of holding 7 rounds of 2.75-inch shells. This allows for a total capacity of 14+1 rounds (7 rounds in each tube).
5. Switchable Feed Tubes: The KSG features a manual feed tube selector switch located on the bottom of the shotgun, allowing the shooter to switch between the two magazine tubes. This feature provides the flexibility to load different types of ammunition or to stagger different loads for specific applications.
6. Pump Action: The KSG operates on a pump-action mechanism, requiring the user to manually cycle the action to chamber each round. The pump handle is located on the underside of the shotgun.
7. Sights and Optics: The KSG typically comes with adjustable sights, including a rear sight with windage and elevation adjustments. The front sight is typically a post sight. Some versions may also feature a Picatinny rail for the attachment of optics or other accessories.
8. Rail and Accessories: The KSG may feature a Picatinny rail on the top of the receiver, allowing for the attachment of optics, red dot sights, or other accessories. It may also have accessory attachment points on the forend for adding grips, lights, or other tactical accessories.
9. Safety and Controls: The KSG incorporates standard shotgun controls, including a crossbolt safety located at the rear of the trigger guard. It also has a slide release button for fast reloading.
10. Weight and Length: The KSG is designed to be compact and lightweight. The specific weight and overall length may vary depending on the specific model and configuration.

It’s important to note that specifications and features can vary across different versions and models of the Kel-Tec KSG. Additionally, it’s crucial to research and understand local laws, regulations, and requirements related to firearm ownership and use, including any restrictions on shotgun configurations or magazine capacities in your jurisdiction.
