I think the older scopes from Tasco, Bushnell, and especially Weaver were great scopes. They had to be, they were the only things out there for many years. However, it's my opinion that as time has moved on, and with the rising costs of production, they are no longer of the same quality they were 20 years ago. One reason being, they've had to make cuts somewhere to keep their scopes within a certain price range. Whether those cuts were materials, or quality control, you still wind up getting what you pay for.
