Thanks for the link, helpful read. Welp, looks like I'll have to arrange a refund of some kind or eat the cost.
I am in between knowing I am a true idiot and hating the CBSA for not considering that it's a toy. Fuck me. I need cheaper hobbies.
Edit: I contacted airsoft global and they'll refund the cost of the item if I have to send it back. What do you all think it's gonna cost? I think they're based in Taiwan so I know it won't be cheap.
