My buddy saw a sign on a gun store where they had a "3 for the price of 2" promotion on M240 machine guns, like who in their right mind would need two of these, let alone three? They proudly displayed "No ID Checks" in their window lettering, too.
At least part of this is a lie. A transferable M240 is like $400k-600k. And in order to sell those, they have to run a background check as an FFL which requires some form of identification.
No, he saw no such thing, at least not in the USA. You need to call him up and ask him why he lied to you, and ask him not to do that anymore.
