I mounted this on my Yamaha Grizzly rear frame. It wags quite a bit on rough roads and the round bolt assembly works loose. It would be more steady if the front end of the scabbard was further forward so you could swivel it further down so the front of the scabbard could be anchored down onto the fender or the running board. I was pleased that the padded scabbard would accommodate my Sako 270 short mag with a Leopold scope and bipods(I have to pull the liner out with the gun each time because of the bipods but not a big deal). Gonna extend the mounting plate forward so I can anchor the front and find a way to pin the round plastic screw so it cant wobble loose from the gun scabbard holder.
