Did the refurbished AKM-63 get vented gas tubes?Well, I have doubts if any AK-63 exported before 1980. This is because based on the FÉG official records about AK-63F (AMM), the factory restarted production of the old AKM-63 with new wood furniture and created the first batch of AK-63F in August 1976 for military acceptance test. Due to bureaucracy, the first AK-63F serial batch started to produce only in November 1979. The AK-63D (AMMSz) started to produce a bit later only in April 1980.
This AK-63 could not be mixed with the older AKM-63 MAT (Műanyag Tusás) equipped with plastic grips and stock. Those guns were refurbished and their plastic parts changed to wooden ones as well as their bare metal gas tube changed to a wooden one. This called AKM-63 FAT (Fa Tusás). This was exported to various countries such as Iraq, Iran, Syria, Egypt, and so on. Gun serials tell the truth.
AK-63 serials pool: GA XXXX - HH XXXX
AKM-63 serials pool: MA XXXX - ML XXXX (with a few exceptions: AKM-63I with infra mount have EA XXXX - EB XXXX serials)
SA-85/SA-85M serials pool: SM XXXXX - SN XXXXX
This picture is from 1980 FÉG's monthly newspaper: "For the celebration of the liberation of Hungary, on April 4, the first series of new submachine guns were produced."

This Iranian Soldier from November 1982 had refurbished AKM-63 which can be distinguished by the lack of slant muzzle brake.

For reference: Refurbished AKM-63's keep their old-style handguard retainer which has an extra hole at their side.
