If an airsoft gun fires lower than 407 fps on 0.22 gram bb's it falls into the category of a "controlled firearm". These airsoft guns must have "clear" receivers, or at least the half of the receiver that the serial number is printed on for the real steel version needs to be clear.
If an airsoft gun fires above 407 fps on a 0.22 gram bb's it falls in the "uncontrolled firearm" category and has no restrictions involving clear, black or metal receivers.
Partially incorrect. Sub 407 is actually a replica. And above 500 is a controlled firearm.
Regardless of the gun laws, it is a bad idea to try and buy any airsoft gun from outside canada. You may be able to get the ones you are looking for in-country, but you'll have to get Age Verified for that. Please read the FAQs.
