> Please source the claim that the legal purchase of firearms by US citizens from FFLs, such as Walmart, is a significant contributor to the presence of firearms in Central America.

For example, one study is at https://nacla.org/article/small-arms-trade-latin-america.

> The U.S.-Mexican border is also a central route through which illicit small arms enter Latin America. A study released by the Mexican government suggests that as many as 2,000 guns are crossing the U.S.-Mexico border daily. As in Colombia, these guns are fueling an arms race, in this case between Mexican drug cartels, costing the lives of 4,000 people in 18 months.14 Weapons, including assault rifles like AK-47s, AR-15s, and M-16s, fetch up to three times their U.S. market value in Mexico, assuring a continued southward flow of weapons.

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.
