I'm posting this with no claim of being a expert of anything.
When I was looking for a quality knob turner scope I asked a gunsmith that I respect & does a lot of tactical rifles for his opinion, his reply; "I don't recommend any scope anymore, they all have problems!" I said,"Come on? Even S&B and Nightforce?" His response, "I've even had them come back with issues." So I redirected my questions as,"So what are on your personal rifles?" His response, "Forget it, I no longer recommend any scopes to friends and/or customers. They all have issues these days."
Of course the conversation went from there to; what kind of issues & why? He shared a lot of information with me which I will not go into here.
My recommendation is buy with in your budget and expected to have issues or get lucky and find one that does not. Truely it is a crap shoot, in my opinion.
