I will need to get a set of big eyes by this hunting season, and have some questions. If I purchase 2 spacemaster scopes, does it matter if they have the rubber coating. I have heard that some of the brackets may not accomodate them. Also, Do the old spacemaster 2 scopes have the same dimensions as the newer scopes. It almost seems that it would be better to buy the whole set already put together, as far as cost. The only place that I have seen, that sells these, is Hart's. Any other places?
