It's an old stock I saw once on a sniper II. It looked to be made out of a black bar, which was bent/shaped like a gun stock. It was a skeleton type stock, and the stock atached to the sniper 2 right below the cocking knob on the main body and to the bottom of the grip frame. I am not sure if the attached picture will work, but if it does, it will explain it. I am not sure if the stocks are made anymore, but I think they may be refered to "wire stocks." I don't know if WGP made them or not, but, does anybody know what I'm talking about? Also, where's a good place to buy a sniper 2 (good prices and customer service)?
