Airrow is a firm that manufactures line throwers & harpoons but the salesmen wanted a hand held version? They did do a partnership with Ruger using their design barrel, Rugers frame, 22 blanks for propulsion that made it to market, but this one was limited to just the 10 prototypes. Interchangeable arrowheads, the arrow loads from the front of the barrel, there is a rail to mount your favorite sight or open are provided. 3000 fps and virtually silent, the SCARIEST piece I own! The serial #?  007, of course  :) In it's original case with an assortment of broadheads, tranquilizer darts, blunts, etc. Might even be legal in Kalifornia? NOT a firearm! Shoots arrows instead of paintballs
