I have contacted, IRG, Fulton, and the RCMP regarding this.
At the current moment, the receiver has been paid for, and has arrived at IRG. Fulton IS licensed for export, as I asked them, and IRG does the paperwork to get it brought in, including getting it an FRT if necessary, which the RCMP told me, shouldn't be too hard, if you actually know what you're doing. It may be a lot simpler to get a FRT for a platform that already exists in-country than a new platform, but I don't know. Also, a single rifle, brought in, as part of the whole end-user-certificate thing, is different than bringing like 300 in for sale, as enefgee has said. I may end up with a very unique item, or I might not.
That's what's going on, at the moment. I won't have any more info until sometime in January, likely. Until then, everything else is just supposing.
