It's one of three of my buddy's pumps and he sold it to me. its a 2k5 (i think) autococker that he converted to a pump. dye boomstick and pistol grip, superfly bolt, single finger sliding trigger, and on off asa. I think its a new reg too... also he kept the front of the cocker (the pneumatics bit) and made that into a custom pump handle, the original barrel and extra asa
