This is a SKS AK 47. I had my sheriff friend over to look at it and he ran the serial numbers (there are 2) and they came back clean. Everything seems to work, the previous owner changed the stock from wood to composite and did a bunch of other things, but for the price, it is a great deal! My wife watched a newer show called barter kings. So she listed an old welder that I haven't used in 10 years and this is what I got. Btw, I paid $50 for the welder when I bought it.
