Upper receivers aloud into Canada?
 

Now i just want to clarify, this because i know you can't ship full metals bodies, as it voids the law of having a clear lower receiver, and will be seized immediately. But would the upper receiver be aloud into Canada? I personally don't mind the smoke lower, it's made out of good quality plastic, and you can't even tell it's clear with a mag in the well. Some info would be great?

Hit and miss, as is a lot of airsoft related items.

There are also issues with matching lowers and uppers properly.

I bet, i have found a G&G gr16 upper,and well if that doesn't fit i don't think anything will! As i have a gr16. Though this isn't exactly priority on my buying list, it's still in the back of mind! Thanks for the help

Uppers are usually fine, though for pretty much all the claer guns in Canada, the receivers come asa matched set, uppers alone are pretty damn rare.

Yeah, the ones i've found are whole front barrel assemblies, not just the upper, but hey if i can get RAS thrown in with the package, mind as well eh?
