HB2544 is a bill that seeks to amend Arizona Revised Statutes by asserting that personal firearms, firearm accessories, or ammunition that are modified within Arizona and remain within the state's borders are not subject to federal law or regulation. This includes exemption from registration under the authority of Congress to regulate interstate commerce. The bill specifies that this exemption applies to firearms, accessories, or ammunition modified from basic materials without significant parts imported from other states.

The bill also requires that firearms manufactured and sold in Arizona must have "made in Arizona" or "modified in Arizona" stamped on a central metallic part, such as the receiver or frame. Additionally, the bill defines "modified" as changes made to a firearm, accessory, or ammunition by a qualified gunsmith. The bill was vetoed by the Governor due to concerns that it could limit federal public safety regulations and create confusion between state and federal laws.
