Ordered a Bushnell Elite 80mm Spotting Scope and Shooters tripod from The Optic Zone. There are minimal instructions with the Elite and none with the tripod. Having a little trouble figuring out how it mounts together, even with the spacer it's not tightening down. Bushnell wanted me to ship scope and tripod to them for repair, fellow at The Optic Zone was not familiar with the tripod. Can anyone help me with this?
