Here is a list to view a few good scopes to consider:

Off the list, I would likely choose the SWFA 3-9x42 SS. Very tank built scope with good internals with spot on adjustment for turret turning. Hard to beat that scope for the money. I would also consider the Weaver 2.5-10x50 Extreme scope. However, there are some Leupolds and Bushnells to consider. SWFA has been a great company to work with and their customer service is second to none.
