Canadian Border Troubles !

I live in Canada and recently ordered a bunch of paintball items form the US.  I had the items shipped to Rydens Border Store in Minnesota. Yesterday a friend and myself went went across the border into the US and picked up the packages (he also had paintball gear sent to the border store).  When we came back into Canada and declared our items, the border agent(s) asked to see specifically two items listed on my receipt - the Alpha Black tactical paintball gun, and the flatline barrel for the X7.

They took about 45 mins to an hour investiagting these items and came back with the conclusion that the Alpha Black is a restricted firearm.  The border agent cited the fact that the manual included did not give out the maximum velocity the weapon can fire and also that the paintball gun was a replica of a real gun.  

The explanation for not allowing the barrell was not clear, as no reason was really given except that it was restrcited.

We told the border agents that the items are sold directly in Canada and in Canadian Paintball stores. We were told by the agents that they are NOT sold in Canada and if they were they came here illegally.   

At one point they border agents called the paintball gun an airsoft rifle and made the case that it can fire metal balls and even told us that they could call the OPP (Ontario Provincial Police) and have us arrested for being in possesion of the firearm.

My friend and myself are not criminals and nor are we teenagers (we are in our 30's).  We were both taken back by the ignorant attitudes of the agents and the complete disregard for the facts.

We were allowed to return the items to the American Border Store (Rydens), where the items are right now (waiting).  I have a couple of options to proceed to try to get my items back, #1) return the items to where I bought them. #2) make a case for bringing the items through (to Canada permanently) again.

Any thoughts or ideas ? 

I'll probably end up shipping the items back to where i bought them.  It's too bad because I got the flatline barrel for an unbeatable price.  Canadian prices are very overpriced for paintball gear, I woud rather avoid buying from Canada if I can. 

Thanks for advice.
