Now that I've scrounged through the specs on the Weavers and the Blackhawk!s and compared them to the Leupolds, I would have to differ with the above statement.

The Leupolds aren't even in the same power range (which I already knew).

The Weaver and Blackhawk! models are, oddly enough, identical in terms of FOV, ER, power ranges, objective size, length, and weight. I'd have to say that if the Blackhawk! is anything, it's a revamped Weaver.
