Hey Hkguns,
There is absolutely no difference between a 1970 Firearms International import and a 1971 Garcia import. Non, zero, zilch, zip. I think I am going to have to post detailed side by side photos of each. Myself and others' answering of this question (No insult to you Hkguns or anyone at all) is getting extremely redundant and should be a sticky or on FAQ. The reason why Pre-Garcia's seem to be preferred is because it has been erroneously used by the uniformed for years. A "true" pre-Garcia rifle would be one with a Firearms International (FI) import stamp, or one made for other than U.S. import made during the the time of FI importation, or a an FI rifle with no stamp made prior to the import stamp requirement outlined by the Gun Control Act of 1968. When Garcia bought out FI around late 1970 ish, they assumed the importation of the Sako production line that was being imported by FI. This production line did not change with the exception of the L61R Finnbear being offered in the Mannlicher configuration. The Sako production line imported by Garcia did not change until the standard sporter changes that occurred with the Model 72, yes, 1972. Hence the correct term, Pre-model 72. For further, proof, I would be happy to post photo's of the Last FI catalog, 1969-1970, and the following year catalog by Garcia. Same photos, same words etc. So, to recap my more than likely, difficult to follow explanation, here is a timeline, which for here, is approx. within one year (does not address non-imports)
Up until 1968 - Rifles were imported to the U.S. by Firearms International and had no import stamp.
1968 to Mid 1970 - Rifles were imported to the U.S. by Firearms International and had the F.I. import stamp.
Late 1970 early 1971 - Garcia took over importation of the Sako production line previously established by F.I.
Late 70, early 71 to 1972 - Rifles imported to the U.S. by Garcia were of the same production line as the F.I. imports with the exception of the addition of the L61R finnbear mannlicher, and of course the Garcia import stamp.
1972 - Garcia/Sako developed for the U.S. market the model 72 (L61R Finnbear, L579 Forester, L461 Vixen) with mostly cosmetic changes to replace the 10 year old standard Sporter. Garica also dropped the importation of rifles with the Mannlicher stock.
Disclaimer: There is more than likely overlap on the dates and they are approximate.
