Rolln. Almost all the stocks for MX guns listed on the forum will bolt on your gun. But I recommend you work with the one that came to the dance. If your gun has a pad adjuster, you can pretty much go from a modified heads up to a traditional locked in cheek/eye socket position. The "canoe" style comb is petty much all your face hits and that allows for more "cast off" than traditional stocks. Set the gun up for POI and shoot it often.
