Maybe the M1A title gets around it. I was looking at some similar stocks with that designation. They were titled M1A but you could see the selector cut out....
The one I got for sure doesn't have the selector notch in it.
However, I can already see the discussion at the CBSA counter. (I am there daily I do importing for a living)
"Sorry, you cannot import an M14 stock."
"It's not an M14 stock, it's an M1A/M14 stock, it doesn't have a selector switch notch. M14S's and M305's are 100% legal in Canada and this is made for them, not a military M14, and it's not a stock from an M14."
"Still, it's not legal to import."
"It is. You can call the CFC or CFO right now and they will tell you that is incorrect. I'll call the CFO right away and we can talk to them together so we can clear this up."
"Sorry, I am not going to do that."
"No, you mean you're 'choosing not to do that.' Calling them will resolve this matter to the letter of the law and I can get my import."
"No, I am just not going to do that."
"Selective enforcement. Got it. I'll call the CFO myself and have them call you directly. I am no rush for the stock. Tomorrow or the next day is fine with me."
Usually by the time I walk away from the desk, they end up calling. And I have had this fight with them before. Usually after a 10 minute back and forward, it always works out, but not after exhausting time.
