SKS rifles are interesting - I see some for $600 at Cabelas, must be something special for collectors, not that long ago $300 bought a shooter in pretty good shape, and when they were first becoming popular in the 1990’s big 5 was selling them for $99.97.
If someone wants a shooter they may like your stock, but for collectors there are too many with all original parts. I have no idea what shooter- quality rifles are going for today.
