Not sure what your looking for,but I have several.One on my 77-22,both sons 77-22s,wifes 77-22,my Ruger #1 45-70.Its a good choice on a short range rifle,works good in low light,heavy brush,moving targets,ect.Holds poi,positive adjustment,Don't move it very much but they seem to track ok.I think you can buy them new for $500.00 or less.I bought a few used ones for less than $200.00.Hope this helps, Lightman
