I personally never could get a 98 folding stock to work with the adpater. Because the joint is so close tot he end and the adpater end piece has to slide a ittle bit down the stock in order to get everything put together. I would like to see the picture of how someone did it if they did.
Ah I registered their so I could see. Yeah it doesnt say what he had to do to get the folding stock to work. But I took a dremel to mine. Made the end so weak it broke. It probrably can be done and effectively but its not going to be a buy it in the store add on. You will have to ultimately modify it.
