Weird stock with welded on tank bracket used. Fits 7oz tank I believe. A T stock, T is welded on. Length of stock is 13 inches. Height is 5 inches. Width of stock portion is .75 inch width. Width of butt is 1.25 inch width. Has 1 giant thumb screws for securing tank. Tank mount is welded on, see photos. Kind of a neat stock, the tank mount is at an angle. Not sure who made this. Came with an Automag out of Illinois. Kinda neat.
