KelTec KSG

The KelTec KSG is a bullpup 12-gauge pump-action shotgun designed by KelTec. The KSG has two tube magazines which the user of the gun can switch between manually. Each tube holds up to seven 2.75-inch (70 mm) 12-gauge shotshells or six 3-inch (76 mm) shotshells. The KelTec KSG has an overall length of 633mm. KelTec has also introduced a larger variant, called the KSG25, which holds 24+1 rounds to the original's 14+1 rounds. Barrel locking is achieved by a swinging wedge, located inside the top of the bolt, which engages the barrel extension. The sliding forend is connected to the bolt by dual operating bars. The ammunition feed is from two independent tubular magazines, located below the barrel. The user is required to manually select a magazine by switching a three-position lever, located behind the pistol grip. The middle position of the switch blocks the feed from both magazines and allows the user to chamber a single round manually.
