I like weaver scopes. They are clear and track well. I have a few kaspa scopes and seem to work just fine. I trust them more than the cheap Leupolds which I have sold. I do not know about their warranties never had a issue yet.
I have one 3x9 and a 6x18 Kaspa. The 3x9 is not on anything. Most of my weavers are in the Classic series.
