Liberal democratic senator David Leyonhjelm has appeared in a video for the National Rifle Association of America in which he describes Australia as a "nation of victims" because of the government's tough stance on gun control.

In an interview, the anti-gun control senator warns the United States not to follow Australia's example after presidential hopeful Hillary Clinton said a gun buyback scheme similar to the one John Howard introduced in 1996 was worth considering.

"I don't think Australia is a model for the United States on gun control at all," Senator Leyonhjelm says in the NRA clip.

Australia's strict gun laws have been a talking point during the US presidential race, where advocates of restrictions have pointed to the fact there have been no gun massacres in Australia since 1996.
