Three of us ordered Chaparral NWMP carbines from Six Gun Shorty and got great service.

Then we used Questar International to do the imports and that went without a hitch but it is a bit on the expensive side.
http://www.questar.ca/ Questar's estimates regarding times turned out to be a little longer than it actually took. It takes Washington somewhat longer to process the export than it does Ottawa to do the imports.
I don't know of anyone who has bought an Uberti, but I would expect that would be simpler since there are a number of Canadian retailers handling Uberti products. I'm interested to see if anyone pops up who has.
