Depending on how deeply you get into variations ,it is a copy of the the Chinese type 56 with copies of the East German MPiK pistol grip and stock. It is not known if they received Chinese machine tools/dies to make these or if they reverse engineered them. They had received a large number of EG MPiK's , North Korean Type 68's, and Chinese T-56's before and during the Iran/Iraq war. There was a thread a ways back that went into some detail, at least as much as we have been able to scrape together, but I could not find it.
