T4E Double Barrel Shotgun. Sold for home defense. Takes 12g Co2 . 200 FPS. This is the 6 joule model. I tried modifying it to 12 by removing the air restrictor. I was successful but when putting back together a spring popped out so the barrel doesn't pop up when the button is pressed and you can see it needs some tightening. Only shot a few times. Will throw in a 500 count bag of .68 cal paintballs.
