Undetectable Firearms Modernization Act

What this bill does

AI plain-language summary

This bill changes the rules about how detectable firearms must be. Current law requires firearms to be detectable by metal detectors after removing grips, stocks, and magazines, and they must be as detectable as a 3.7-ounce piece of stainless steel shaped like a handgun. The bill would require firearms to contain detectable material after removing all parts except major components, where detectable material means something that creates a magnetic field like 3.7 ounces of stainless steel. The bill also expands exceptions for firearms owned by or made under contract with the United States government.
