A 222 was built on a L461 Vixen (short) action.
A 308 was built on a L579 Forester (medium) action.
A .30-06 was built on a L61R Finnbear (long) action.
That’s a Firearms International L579 Forester (pre 1972, pre-Garcia gun). The recoil pad is not original to the gun. In addition to the Forester Mannlicher carbines Sako also manufactured a much rarer Forester Mannlicher with a full length barrel during the same time period.
