the older models, such as the ssr99, were top shelf.

the hungarian/polish ssr85a and b akm based models were also pretty nicely done.

the ssr56 (hungarian or orf receiver/bulgarian and chinese parts mixture) has a spotty quality record backed by a spotty customer service record.

ssr99, in the bulgarian forum, can give you a much more accurate and detailed breakdown on the history of globaltrades/arsenal usa.
