SPRINGFIELD (AP) – The Illinois House on Tuesday voted in favor of bans on semi-automatic assault weapons and large-capacity ammunition magazines, though the proposals still face several legislative battles before they could become law.

The approved proposals were six amendments to a bill that House Speaker Michael Madigan left blank on purpose, and they were okayed in an unusual process that Madigan began using last week to allow legislators to debate at length on contentious topics. The House still must approve the full piece of legislation for it to move to the Senate, and none of the six votes taken Tuesday as lawmakers debated what would go into the measure had the same support as what is required for a bill to pass the House.

One of the amendments would make it a felony for anyone to sell, purchase or transfer a military-style assault weapon. Should the amendment become law, it would make it illegal for civilians to possess these types of weapons after a 300-day period following the measure’s enactment.
