I think the US import rules depend a lot on whether or not the rifles were sold or lend/leased. If they're lend/leased then the US Gov. never lost ownership of them and they can be re-imported. Didn't the last batch of CMPicon Garands come from Greece? Please correct me if I don't know what the hell I'm talking about.

Besides, you'd have to sell them for $99.99 if you wanted to move that many in just the Canadianicon market.
