I just purchased a Sightron 10 50x60 scope from member on this forum and had a terrific experience. Having said that, I am new to this forum and new to long range shooting. I am working with serious budget constraints, so I'm wondering if anyone knows if and who makes a less costly side focus wheel that would fit my Sightron. They make a nice one but its $130.00 dollars and just a tad out of my range at the moment. Any input would be appreciated.
