While we all have every right to be upset with our politicians and the RCMP Bureaucrats, it was found that CZ was modifying full-auto receivers to make them semi-auto only, which CZ should have been aware of when they began selling the firearms to Canadian's as a Canadian Non-Restricted Firearm.
This is in no way meant to be taken as being an apologetic post with regards to our ridiculous laws or the ridiculous individuals that interpret them how they see fit, but it is another way of viewing the issue.
In the end I would feel that both parties are to blame. Our government and the RCMP need to stop bowing to media hype, and view issues objectively. While at the same time, so long as the laws are on the books, CZ should have had a better understanding of them before selling a product that could have ended up with their customers losing the product they purchased due to them not understanding the laws.
Fight on to get the laws changed, but maybe try and get a semi-auto designed/manufactured receiver from CZ in exchange for your now prohibited one. You get to use your rifle again, and CZ and re-fab the exchanged receivers for sale in another jurisdiction.
