Has anyone converted a KS-47 to except AK74 mags? I have searched but without much luck. Looks like it has been done but I have not found any details. The barrel would be easy enough, looks like two of the bolt lugs would need to be re profiled. So what about the lower? I do not have any AK74 mags to compare with AK47 mags. How do AK74 mags demensions compare to AK47 mags? Any input would be appreciated.
