means Someone who illegally smuggles guns and ammunition, typically across borders or to embargoed buyers.

from A straightforward compound of 'gun' plus 'runner' — 'runner' in the old sense of someone who moves contraband past authorities, the same sense that gave English 'rumrunner' and 'bootlegger'-adjacent smuggling terms during periods of prohibition and arms embargoes. The word rides on a long tradition of '-runner' terms for people who dodge blockades and customs to deliver forbidden goods.
