I have seen many 7.62 Galil rifles when I worked El Salvador Actually Israeli weapons were scattered all throughout central and south america,even the isreali army helmets.  As a side note I recently spoke with some ex fmln guerillas and they told me that the 7.62 Galil was a ''status'' weapon within the ranks of the rebels,they did not like G3s and also disliked M-16s they instead preferred FN FAL's ,AK's , and most of all the GALIL.
