I stand corrected:
Apparently Flemming did do a 52 type.
It sounds like you have a registered receiver, but if I'm mistaken and you've got a sear gun, I'd get either a 5.56 or 9mm host gun to use for cheaper shooting than 308. If you've got a registered receiver, however, I wouldn't mess with trying to have it hacked up into something like a 52. Now I'm no gunsmith, but as I understand it, the conversion involves some serious work cutting and reforming part of the receiver around the mag well to accomodate the smaller AK mag. Just my $.02, but you've got a great gun, so why risk converting it to someting that may or may not be reliable and may give you problems finging spare parts?
