it is certainly something that peaks my personal interest. I have no qualms using a non-upgraded gun, as that's what my G36 and a couple others that I have had prior. The only upgraded gun I own though is my G3SG1 which is 1/2 in Saskatchewan and 1/2 in Trenton.
Which year did you think this would be going on, and at what time of the year? Also, which state? If you could organize it at a state somewhere along the US/Canada border (MONTANA!) then that would certainly help those of us Canadians that don't live within an hour of the border (5 hours North for me!)
