Calin think of it this way - to import a simple, uncut, .308 rifle barrel, uncut - there are NO Canadian regulations. However you need to meet US regulations, which means you need to receive and do paper-work for Canadian DFAIT (foreign affairs & trade), so that the barrel seller can give that to the US gov't to get export permits. That's a lot of hassle right there. Importing a rifle means that you've got not just double the paper-work, but probably quadruple. And then it probably has to be taken to a verifier, to verify it's what you say it is. None of that is going to be free, if you don't know the ropes already it's going to be incredibly difficult (I had to send the same request 6 times, by fax, no calls or letter) before I could get the gov't to send firearms importing paperwork) and if you try asking for help from people who import for a living they're going to be offended.
