These are the newest Generation Keltec KSG Pump Shotgun in 12 gauge. It is new unfired direct from the factory. This is serious fire power.
From the factory: The KSG is our first entry into the shotgun market. The size, shape and design are similar to the currently available Kel-Tec RFB rifle, but the KSG ejects downward, instead of forward. The KSG weighs 6.9lbs and is as compact as legally possible with a 26.1″ overall length and an 18.5″ cylinder bore barrel. Even with this compact size, the internal dual tube magazines hold an impressive 6 rounds of 12 gage 3″ shells each, for a total capacity of 6 6 1 (7 per tube if using 2-3/4″ shells). The simple and reliable pump action feeds from either the left or right tube. The feed side is manually selected by a lever located behind the trigger guard. The lever can be positioned in the center detent in order to easily clear the chamber without feeding another round from either magazine. A cross bolt style safety blocks the sear, and the pump release lever is located in front of the trigger guard. The pump includes an under Picatinny rail for the mounting of a forward grip, or a light or laser. The included top Picatinny sight rail will accept many types of optics or iron sights. Forward and rear sling loops are built in, and a basic sling is included. The soft rubber butt pad helps to tame recoil.
