Can I Build an AR-15 in Maine?

Yes, you can build an AR-15 in Maine. The state has no specific laws prohibiting home assembly of rifles, and federal law allows personal manufacturing without serialization or registration for personal use.
What This Means for You
Maine follows federal firearms laws without additional state restrictions on home builds. You can legally manufacture rifles for personal use without FFL involvement as long as you're not prohibited from owning firearms. The state's constitutional carry status and gun-friendly laws make it one of the more permissive environments for home builders.
The Detail
Maine operates under federal guidelines for home-built firearms, meaning you can legally manufacture rifles including AR-15 pattern guns for personal use without requiring federal licensing. The key requirement is that you cannot be a prohibited person under federal law, and the firearm must be legal to possess in your state. Since Maine has no assault weapon ban or magazine capacity restrictions, standard AR-15 configurations are perfectly legal.
You don't need to serialize or register your home-built rifle in Maine, though federal law requires that if you ever decide to sell it, you must transfer it through an FFL dealer who will assign a serial number. The firearm must also comply with federal regulations like overall length requirements and cannot be configured as a short-barreled rifle without proper NFA paperwork.
Maine's laws are generally firearms-friendly, with constitutional carry for residents and minimal restrictions on rifle ownership. The state preempts local firearms ordinances, so you won't face a patchwork of municipal restrictions. However, you should still verify current federal compliance requirements, particularly regarding 80% receivers and any recent ATF guidance on home builds.
Keep in mind that while building is legal, you cannot manufacture firearms with intent to sell without proper federal licensing. The build must be for personal use, though you can later decide to sell it through proper channels. Always ensure your completed rifle meets federal length requirements and doesn't incorporate any NFA-regulated components without appropriate tax stamps.
Build Impact
Maine's permissive laws mean you can build standard AR-15 configurations without worrying about state-level restrictions on features or magazine capacity. You should focus on federal compliance and ensure any components you're using meet ATF guidelines for home manufacturing.
