Gun makers can reuse serial numbers on certain firearms, cutting costs

The US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) proposes allowing gun makers to reuse existing serial numbers on certain firearms. This means manufacturers will not have to engrave new markings if a firearm already has an acceptable serial number from a previous maker.

This change makes it cheaper and easier for licensed manufacturers to modify or remake certain firearms, like short-barreled rifles or suppressors. It removes a redundant step in the manufacturing process, which could slightly reduce the cost of these items. The rule primarily benefits smaller custom gunsmiths and manufacturers who often work with existing firearm components.
