Firearm Attachment Amendments

HB 387 creates new criminal penalties for possessing, manufacturing, distributing, or selling machinegun firearm attachments in Utah. It specifically targets devices that convert semi-automatic firearms into fully automatic weapons, making these actions illegal for all ages. For adults (18+), violations are classified as class B misdemeanors, while minors under 18 face third-degree felony charges. The bill directly affects anyone handling these attachments, with stricter penalties for younger offenders, and amends existing firearm laws to include this new category of prohibited items.
