I bought this one as a 'scratch and dent/mismatched' special from AIM.
$59-delivered.Its the most rifle per dollar I've ever spent. It had some pretty big gouges in the stock and a bit of rust on the exterior, but it shoots.
The first time I ever bought a K-31, I actually bought two of them. I bought them for use in military rifle matches, and bought the 2nd just for the magazine. This was at a time when chargers were nearly non-existent in the US for these rifles- they are still hard to find and/or very expensive.
