Arms Export Control Act & selling parts

[uniformer]

On many of the gun parts (grips, stocks, rails, handguards, etc) that customers purchase to personalize their long guns, there is a warning label printed on the box "This item is subject to the Arms Export Control Act (22USC 7228) and the International Traffic in Arms Regulations (22 CFR Parts 120-130. A prior authorization or license.... etc etc)"
My question - if I sell such a part, such as a stock or grip, to a Mexican who lives in Mexico, but who I don't know is a Mexican citizen/resident (speaks perfect English, just comes in the store to buy a grip), can I be in trouble later if DOJ or ATF finds out I sold this part that ended up in Mexico?

Exporting firearms, firearm parts, firearm accessories, ammunition, and/or ammunition components without the US State Department's permission is a Federal felony.

Prior to shipping any of those items to another country, you will need to get approval from the US State Department.

If you are selling parts, not firearms in the US and delivering in the US, you have no obligation to verify the buyers citizenship status. If the new owner of the parts chooses to break the law later, that is not on you.
That being said some common sense is needed. A guy buys one or two stocks, no problem. A guy buys 200 stocks will be a little fishy.

I'm not sure the quantity is really relevant to the OP getting in trouble. They have no liability to the federal guidelines if they sold all their product within the US.

Now if the buyer said "Hey I'm exporting these all to Mexico tomorrow give me everything in stock" then there is a possibility they could be linked to the transaction.

The buyers residency / citizenship is irrelevant as well. If Mr Joe White walks in buys 1 or 1000 grips and then exports to Mexico he's still breaking the law as quoted above.
