The Undetectable Firearms Act was introduced into the 100th Congress back in the year 1988 by our good friend William Hughes. Yes, that Hughes. It was in response to the big plastic gun scare that was whipped up by Handgun Control Inc, former name of the Brady Campaign, back in the days when they were relevant. NRA opposed the original bill, but dropped opposition to the bill once its requirements no longer met the the criteria of any actual guns currently in production. In other words, the bill had no actual, practical impact.
If nothing is done, the UFA will expire on December 9th. This is not the first time it has has been set to expire. The first expiration date was ten years after the first enactment, in 1998. In 1998, it was extended for five additional years. In 2003, it was again extended for an additional ten years. Given that it’s been readily extended by both parties, I have no expectation that we have a prayer of stopping extension. The big threat is that the UFA will be expanded to include a ban on manufacturing a polymer receivers or magazines by non-FFLs, even if the polymer used is doped with a chemical that renders it radiopaque, or is made from a polymer that is dense enough to be easily x-ray detectable. This is because it also must contain enough metal that it sets off an x-ray machine calibrated to the security exemplar. The existing UFA law regarding metal content only applies to the entire firearms, minus grips, stocks, and magazines. By creating a separate requirement, applicable only to non-licensees, it effectively bans home fabrication, or smithing done under the auspices of a dealer FFL, which is typically sufficient for gunsmiths. Additionally, it also creates a requirement to have a manufacturer’s FFL to create magazines, which is not currently the case.
I am not optimistic we have the juice to stop UFA renewal outright. We haven’t any time in the past, when this outlawed what only existed in the imaginations of our opponents. But 3D printed plastic guns have been all over the news. Even people at work are asking me about it the topic. We might all know this is really nothing new, and that a plastic gun is about as much of a threat to the person pulling the trigger as it is to the person it’s being pointed at, but the public does not generally know these things. This law getting expanded to restrict hobbyists is a very real possibility, and something worth contacting your congress critters over.
