What Is a Firearms Conspiracy?

A federal indictment in the Southern District of New York charges three individuals with conspiracy to traffic over 50 firearms, including Polymer80 “ghost gun” kits and Glock switches. This isn’t a movie plot; it’s a real-world example of a federal firearms conspiracy charge, and the penalties are severe. For responsible gun owners and FFLs, understanding where legal acquisition ends and criminal conspiracy begins is critical.

The Legal Definition: More Than Just a Plan

Under U.S. law, specifically 18 U.S.C. § 371, a conspiracy is an agreement between two or more persons to commit a crime, coupled with at least one overt act in furtherance of that agreement. A firearms conspiracy applies this to violations of federal gun laws. The key is the agreement. Prosecutors don’t need to prove you successfully trafficked a firearm or completed a straw purchase. They must show you knowingly agreed with others to violate laws like the Gun Control Act or National Firearms Act. An “overt act” can be as simple as a text message discussing prices, driving to a meet-up location, or purchasing a specific component like a stripped frame with the intent to build an illegal firearm for sale.

Common Scenarios That Trigger Conspiracy Charges

Most cases we see involve straw purchasing schemes or illegal trafficking networks. A classic example: Person A, who can legally buy firearms, agrees to purchase multiple police trade-in Glock 23 Gen4s from a dealer like Californiagunshop on behalf of Person B, who is a prohibited person. If they communicate about it and Person A makes the purchase, both are in a conspiracy. Other scenarios include groups agreeing to buy “off roster” handguns in bulk to resell in restrictive states, or coordinating the assembly and sale of unserialized firearms without an FFL. Even discussing plans to convert a semi-auto with a forced reset trigger (FRT) into an illegal machinegun can be the basis for a conspiracy charge before any part is ever installed.

Components and “Constructive Possession”

The conspiracy net often widens with parts. Law enforcement uses the doctrine of “constructive possession”—you don’t need to physically hold a completed illegal firearm to be guilty. If you and another person agree to build machineguns, and you source the triggers while they source the receivers, you’re both in constructive possession of the planned device. This is why the legal status of components is so fluid and hotly contested. For instance, possessing a standalone FRT trigger is one thing. But if your texts show you and a friend bought it along with specific jigs and lower receivers with the express plan to manufacture automatic weapons, you’ve crossed into conspiracy territory. The ATF examines intent, and group intent is easier to prove with communication records.

Penalties and How to Stay Compliant

The penalties for a federal firearms conspiracy are no joke. They can include up to 5 years in federal prison on the conspiracy charge alone, plus consecutive sentences for each underlying substantive count (like illegal transfer or possession of an NFA item). Fines are steep, and you will lose your right to own firearms permanently. Compliance is straightforward: transact only through licensed channels. If you’re buying a case of 9mm ammo or a new handgun from our Semi-Automatic Handguns collection, do it for yourself, through a proper 4473. Never agree to buy a firearm for someone else unless you are both present at the FFL and the recipient passes the background check. Document your builds for personal use, and understand that selling any firearm you manufacture requires an FFL. At Californiagunshop, we provide the parts for legal builds and ownership; it’s the customer’s responsibility to know and follow the law.
