Its not just BSA, scopes in general took a turn for the worst a few years ago, when all the cheaper manufacturers started getting their scopes made in china and the phillipines, instead of japan, around the time tasco went bust roughly. I always bought tasco years ago, because they were jap, and also had a BSA 4x40 that was jap, and that was one of the finest scopes i,ve ever owned.The cheapies are ok until you turn up the mag, i,ve just got stung again, i bough a hawke for my rimfire, and its truly garbage.Quality comes at a price scopewise, unfortunatly, there are no bargains anymore, except maybe weavers, they are excellent for the money, otherwise, these days i buy leupold, or european.
