Can I Build an AR-15 in Minnesota?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
Yes, you can build an AR-15 in Minnesota. The state allows home firearm manufacturing for personal use without special licensing, following federal guidelines for unserialized firearms.
What This Means for You
Minnesota doesn't impose additional restrictions beyond federal law on home firearm building. You can legally manufacture firearms for personal use without going through an FFL, as long as you comply with federal regulations. The key requirement is that you cannot build with the intent to sell or transfer the firearm.
The Detail
Building an AR-15 in Minnesota follows standard federal guidelines under ATF regulations. You can manufacture firearms for personal use without a federal firearms license, provided you're legally allowed to possess firearms and don't intend to engage in the business of manufacturing. The firearm doesn't require serialization if built for personal use, though you may choose to add one.
You'll need to ensure your build meets both federal and state configuration requirements. Minnesota doesn't have an assault weapons ban, so standard AR-15 configurations with detachable magazines, pistol grips, and collapsible stocks are legal. However, if you're building a pistol variant with a barrel under 16 inches, you'll need to follow federal pistol regulations or file for an SBR tax stamp through the ATF.
The build process itself is straightforward from a legal standpoint. You can purchase all components including complete upper receivers, lower parts kits, and 80% lowers without special permits. If you're starting with an 80% lower, you can complete the machining yourself. Completed lower receivers must still be transferred through an FFL since they're considered firearms under federal law.
Minnesota does require background checks for all handgun transfers, including private sales, but this doesn't affect your ability to build. Once completed, your home-built firearm is treated like any other firearm you own under state law. You should verify current state regulations before beginning your build, as firearms laws can change.
Build Impact
This makes Minnesota a relatively builder-friendly state where you can complete standard AR-15 builds without navigating additional state-level restrictions. You'll have flexibility in configuration choices and can source components normally, though you should stay current on any legislative changes that might affect future builds.
