rates at a 5. It is among the very best in scopes. There sure are a lot of guys using them in benchrest. There are a few guys going to the March scopes now but they are more money yet. The variable 60 power is sweet on the March. The BR model is the same glass as the NSX. For about $400 less you can have one of those. Biggest difference is the NXS has Side focus and 1/4 mill clicks the BR has an OA and 1/8 mill clicks.
