The Yugo is a Mitchell import. Originally marked AK47 and referred to as the M77, the AK47 was scratched out and M90 was electropenciled in to comply with the original assault weapns ban. The bayo lug was ground and a thumbhole stock was added. It is in .308 cal., and M14 mags can be modified to fit. It has an AK style scope mount, but only the rail designed for this mount will work.
