Two brothers convicted of running ghost gun factory that produced untraceable 3D printed firearms — used 3D printers to build gun frames while associates purchased other parts on eBay

Brandon and Justin Nudelman, both from Staten Island, New York, are due to be sentenced after being convicted of running an illegal operation selling untraceable 3D printed firearms, also known as ghost guns. According to SILive.com, the duo’s operation started out as an idea around a pool table and eventually turned into a full-blown interstate operation, complete with sports cars and houses featuring secret rooms and compartments.

However, a 3D printed gun frame is not enough to build a complete ghost gun. You still need other parts, like barrels, slides, magazines, and springs. Mershon said during the trial that another associate the group met online, Michael Daddea, helped them purchase these parts on eBay, allowing them to complete the firearm and sell it online. He also helped with the sale and transfer of these weapons, which buyers called “pole, thang, piece, or stick.” Aside from selling ghost guns, the group also 3D printed and sold conversion kits dubbed “Nintendo”, which added a switch allowing weapon owners to turn a semi-automatic gun into a fully automatic firearm.

Despite being run by a small group of people, this wasn’t a simple operation run out of the basement of somebody’s house. The group stored the manufactured guns in a mobile home in Pennsylvania to avoid scrutiny, while Brandon Nudelman had a hidden compartment in his Lamborghini where he kept a handgun. That storage space only opens after a specific button sequence and putting a special pen in a cup holder. Aside from that, there were also several secret compartments in Nudelman’s house which Mershon only saw after Brandon’s arrest.

Law enforcement and authorities are having issues with ghost guns, with their use skyrocketing in recent years. One high profile case included the assassination of United Healthcare CEO Brian Thompson in late 2024, with the alleged perpetrator using an untraceable 3D printed firearm. This has led to multiple attempts by several states to crackdown on 3D printers’ ability to print just about anything, including firearms, with New York, Washington, California, and Colorado introducing legislation to address the issue.

Unfortunately, most of these laws are draconian and many 3D printing enthusiasts are concerned that these will limit their creative freedom while not really being effective at addressing the issue at heart. In fact, we’ve seen a tech enthusiast create a shoulder-mounted guided missile launcher using a 3D printer and readily available electronics, with the entire build costing just $96. Researchers are also taking steps to help identify ghost guns, with one team looking to embed digital fingerprints into 3D printed parts and another group attempting to link ghost guns to specific filament brands via chemical fingerprinting. However, these are still in the research phase, and it will take time for them to be implemented if they’re viable.

    Any tech can be abused wasn't surprised that 3d printers being used for this.

    These proposed laws are completely redundant. The state governments will have to overcome at least the first amendment in regards to these 3D printer laws. It is already illegal to manufacture firearms with intent to sell without serialization and having an FFL. It is already illegal to manufacture parts to convert or outright making fully automatic firearms with or without intent to sell.

    The ATF "ghost gun" rule (2021R-05F), effective August 24, 2022, redefines "frame or receiver" to include unregulated kits and parts that can be "readily converted" into functional firearms. It requires manufacturers and dealers to serialize these items, conduct background checks, and maintain records, making them traceable. On March 26, 2025, the Supreme Court upheld this regulation in Bondi v. VanDerStok, confirming ATF authority to treat these kits as firearms under the Gun Control Act of 1968.
    The rule does not ban making firearms for personal use, but it does require that the core components be serialized and sold through licensed channels, ending the sale of fully untraceable, home-assembled

    How many shots can you get with a plastic receiver before the buffer tube comes loose?
    But I suppose with the extra money people were paying to get one pre-assembled on top of whatever motivation they had to get an obviously unregistered firearm in the first place are also indications of not thinking things through.
    Any law enforcement that sees someone with a plastic receiver on their AR is not going to have to think too hard to know something is not right.

    If we are talking an AR-15, the buffer tube only houses a captured spring that propels the BCG back into battery once a round is fired and cycled. The tube itself can be made of aluminum, the BCG out of the usual tool steel, and same with the spring. Its really only the lower, and potentially the upper on an AR-15 when 3d printed that is usually plastic of some composition. The buffer tube is very unlikely to 'come loose' if it was a metal tube screwed into a plastic upper receiver.

    So, once again we see the foolishness of restrictive laws aimed at the law abiding people. Some criminals used technology to commit several crimes, again. The resolution, again, is to punish and penalize those people who aren't criminals and do not commit crimes. Instead of targeting and punishing the problem, i.e criminals. So, now 3d printers or supplies or both will be modified to comply with some asinine law. No doubt at increased expense or requirement to purchase and own the device. While the criminal element will, again, ignore the law and find some way around those laws and requirements. Another "experts" are idiots scenario. How about establish punishments and penalties for criminal actions and behaviors and, importantly, target those people ? This is not difficult, even for politicians. Challenging, but not difficult.
