I got 4 Russian from Tradex last year, all were pretty decent refurbs, some more 'furbed then others, but they were $179....typically the later made the better the condition was. I asked for 2 early non-chromed bores and 2 late chromed, one was a 1950 with the spring loaded firing pin, both late made were in better overall condition.
I only shot one so far and it was a 1955 with birch stock, chrome bore, and shot waayyyy better then any other SKS I have ever owned. I sold off Chinese and Yugo SKS rifles in the past because they were minute of barn door.... This one is about a 2moa shooter off a rest at 100m.
