Modifies provisions relating to unlawful possession of a firearm

HB 2136 makes it unlawful to possess a firearm if someone has a felony conviction (state or federal), is a fugitive, mentally incompetent, habitually intoxicated, or not a U.S. citizen. It classifies unlawful possession as a class C felony, but upgrades it to a class B felony if the person has a prior conviction for the same offense or a dangerous felony. The bill excludes antique firearms from these restrictions. This law directly affects individuals meeting the specified criteria, altering penalties for firearm possession under these conditions.
