I was examining an AK and would appreciate some insight into what it was.
It had a milled receiver with a well-done blued finish and decent wood that appeared to be walnut. It had no apparent manufacturer’s information on it, but has M22 on the left side of the receiver, a little ways from the serial number. The only markings on the right side of the receiver were near the front: a K, an A, and a B (proof marks?). It had a receiver-mounted sling loop.
