Bill Summary · HB 2159

Legislative bill overview

HB 2159 proposes to prohibit the manufacture, sale, transfer, and possession of bump-fire devices and similar accessories that increase a firearm's rate of fire in Arizona. The bill treats violations as felonies and establishes penalties for illegal possession or distribution of these devices.

Why is this important

Bump-fire devices allow semi-automatic weapons to approximate fully automatic fire rates, raising concerns about mass shooting capabilities. This bill reflects ongoing national debate over regulating firearm accessories versus protecting Second Amendment rights, with potential implications for Arizona's current permissive gun laws.

Potential points of contention

  • Second Amendment interpretation: Supporters argue devices circumvent automatic weapon bans; opponents contend they're protected accessories and the bill infringes on constitutional rights
  • Enforcement challenges: Questions about how law enforcement would identify and prosecute possession of devices that are difficult to distinguish from regular stocks or triggers
  • Definitional scope: Unclear what qualifies as a "bump-fire device" or similar accessory—overly broad definitions could capture legal products; overly narrow ones could be ineffective
