FN and H&K both are not US companies.
“Almost all small arms we procure are made in the USA.”
Contracts require CONUS production facilities, but the companies and designs are foreign.
FN in South Carolina is just an American subsidiary of FN Belgium. FN makes a good chunk of our weaponry (M-16A2, M249 SAW, M240, etc.).
Still, they’re made in the USA.
Good enough for me, unless you want to go for lesser, American-designed options.
