The Fixed 4X Bushnell rimfire scopes have done well for me ,but curiously enough the Bushnell rimfire variable doesn't have an adjustable focus,which I need for my eyes.Seems to me the fixed power scopes have less to go wrong (good factor in a cheap scope)
For my purposes, the ideal rimfire scope would be a simple, fixed power,basic scope, no batteries or electronics or anything to go wrong.Bright clear optics .50 yard parallax covers 90% of my shooting
Why NIKON stopped making the Prostaff 4X rimfire I don't know...it had all the criteria I was looking for and was relatively inexpensive
