I have made several they work good but depending on the jack they wobble side to side, as a result of having play in them. (some are better than others) Sorry I don't have pictures of any of the rests at this time. Pick a jack with less play in it and with a little ingenuity you could find a way to lock out the wobble, I just haven't spent anymore time perfecting the ones I've made. Good luck! Shoot straight!
