"I think it's likely the people pushing for restrictions or bans on semi-automatic rifles want them as a stepping stone to additional firearms restrictions" I think it's more like a culture war -- go after the enthusiasts and influencers first. Take away someone's rifle when they got it from their grandfather, and you take away one rifle. Take away all of the young enthusiasts' rifles, and you also take their friends and family out of the picture for generations hence; and take away a lot of revenue from the industry as well.
