Any scope that does the job is a good scope we might all agree. I will "in my own opinion" that the hands down best scope you can get is a goldring from Leupold.
Three reasons:
1-NO question's asked lifetime guarentee. Bought one at garage sale for 5$that had a scratched lense. The guy obviously a. did not care, or b. did not know how Leupold operates with their warranty. I sent it to Leupold and got somethig I did not expect, not a fixed lense, a brand new scope. I wrote them a nice ty letter.
2-I have 3 Leupold g-ring scopes one was my dads he bough a dogs age ago. The clarity in that scope is no different than my brand new ones.
3-Superior optic's hands down. Unless you want to get into military type optics you can get into nightforce optics or U.S optics which are all outstanding. But they do not offer no questions asked lifetime guarentees like Leupold does. You break it, they replace it. Now that is service!
Any scope is good so long as it makes you happy. But if you want a scope that will not let you down, is rugged and extremely good opticly, has a great warranty and you can save a few dollars for them, they are well worth your while.
