I've never had a problem with my Leupolds, but will soon be in the market for another scope. A lot of the Leupold bashing here on the fire seems to apply to the newer scopes, so I'm OK looking for used. Is there a bright-line test that a person can apply when looking at used Leupolds? Like year of manufacture, or somesuch.

Thanks!
