You can test out the stippling on something else thats plastic, but the "melt rate" will be a little different. If that makes sense. There's a gillion ways you can do it once you get and idea of what happens when you apply the tip to the stock. Also the shape of the tip will make a difference. One warming is a pointed tip going deep will somewhat "perferate" the stock.
As for the rings, will the scope sit in the ones from the factory? The Lows modified will put the tube .412 off the receiver.
