Sorry, the model is the LM4 as stated above. Here is the link at the store I bought it from:
It says 380FPS on that site, but US site says 360-380. I would argue to CBSA that as long as one BB in the test group fires above 366, then the weapon can "cause serious bodily injury" and classify as a firearm.
Metro, I believe you misinterpreted paragraph 5d. The < 500FPS means that it is 'uncontrolled' firearm rather than 'controlled' firearm, but a firearm nonetheless. No license required.
