Home Depot Adjustable Butt Stock

I made an adjustable & Removable Butt Stock using a Rafter Hook that I purchased from Home Depot. I needed something for the 9 oz. co2 tank.

I was lazy and just had it taped to the tank, but I was board today so I placed it in a vise and heated it with a propane torch so I could bend the front hook until it matched the curve of the 9 oz. tank.

I think the hook was less than $3 at HD.
