Airsoft KWC SW40F handgun

This is an AIRSOFT handgun. It comes with 14 Remington CO2 cartridges. It has 2 different endings for the Co2 cartridges, one that you can screw on and off with your fingers and the other needs the allen key which I'll include. The picture included is from Camouflage you can see it listed at $170 plus tax and also it's out of stock everywhere I've looked.
