Essentially, to my understanding, the whole Cansoft idea was created as a method of clearing customs. As a general rule, if the gun looks real, with a solid paint scheme, then the odds of it clearing customs isvery, very low. Of course, there have been cases where these such AEGs have made it through customs, but they seem to be very few and far between. In an attempt to market products to Canada, major producers of these AEGs implemented a plan to produce their AEGs with clear lower receivers, which denotes the gun as "not real". These such AEGs have a much higher chance of clearing customs, with the small chance of being confiscated mainly attributed to the judgement of the customs officials. You never know, the official might be in a bad mood, just heard that his wife has cheated on him, and decide to be a prick and confiscate the item... Catch my drift?
