Stryke Arisoft?
 

I do apologize if this has been posted, but I'm looking for a 16inch RAS/RIS rail system or what ever you want to call it. and so far only Madbull makes them. and after staring at their site for and hour, I found a few retailers which carry one of them being Evike, but dude to the horror stories I've heard of them shipping to Canada I'm staying away from them. now i found a website called Strykeairsoft.com, I was wondering if anyone had any prior experiences with dealing with them? also I'm rather confused as to which mail courier I should be asking for if I do order from them...United States Postal Service, or United Parcel Service (they offer Worldwide Expedited, and Canada Standard)

Take United States Postal Service (USPS). The other (UPS) will rape you on border fees.

will do, thanks for the advice man

Indeed. You should try a local alternative. I recommend https://w2c.ca/.
