Exceedingly small numbers of civilians hold M-16s legally in the US. If there are M-16s going over the border the source is military or law enforcement.

M16s are only a part of the problem. AR15s and ordinary 9mm handguns can be had in Walmarts or "conveniently" bought without any background checks/documentation on private sales.
I mean, I understand the appeal on having a 9mm at home for self defense, and a hunting rifle for, well, hunting - but having AR15 or worse for everyone at a supermarket? And then the ability to sell 'em on without any record of the transferral? I don't get the US on gun rights sometimes.
