The Kel-Tec KSG is a bullpup 12-gauge pump-action shotgun designed by Kel-Tec. With a mostly polymer frame, the KSG’s most notable feature is its two tube magazines which the user of the gun can switch between manually. Each tube holds up to seven 12-gauge shotshells and the ability to switch between magazine tubes allows the user to seamlessly transition between different types of shot depending on the given situation. There is currently only one model of KSG which is the Tokyo Marui Airsoft KSG Gas Shotgun. Being powered by green gas allows for the airsoft KSG to have a realistic pump and firing action, the airsoft KSG does use the Tokyo Marui shot shell system where what it lacks in realism it does make up for in ease of use allowing for more convenient gameplay.
