I don't know weather a magpul stock would be allowed or not, I'm just saying it warrants further investigation
It is a stock, not a firearm, why shouldn't you be able to send it.
Its considered a "defense article" under ITAR.

Canadian law isn't the problem, its US law that prohibits the export of certain items.Adjustable stocks are allowed... Not sure if the one you sold is allowed though.
.. however the BATFE could use a refresher...
Several firearms accessories stores in Canada sell Magpul products
On what?
ITAR has nothing to do with the ATF.
