Have you ever seen a nice scope ruined by crimp marks on the tube, I've seen plenty, that's why you pay the extra, all mounts will hold your scope on the gun, but cheap ones are not properly aligned and will cause crimp marks on your expensive scope, if you can't afford new decent mounts, someone will sell you some second hand, I like to use sportsmatch on my guns and they are all second hand, atb Daz
