Yes, you can legally build an AR-15 in New Hampshire. The state has no specific restrictions on building rifles for personal use beyond federal requirements.
What This Means for You
New Hampshire is generally firearm-friendly with minimal state-level restrictions on rifle builds. You'll need to follow federal regulations regarding receiver manufacturing and serialization, but the state doesn't add additional hurdles. This makes New Hampshire one of the more straightforward states for home builders.
The Detail
New Hampshire allows residents to build AR-15 rifles for personal use without requiring state permits or registration. The state follows federal guidelines, meaning you can manufacture a rifle for your own use without an FFL as long as you're legally allowed to possess firearms. You cannot build with the intent to sell without proper licensing.
For the receiver, you can start with an 80% lower that you complete yourself, purchase a stripped lower through an FFL, or machine your own from raw materials. Federal law requires that any firearm you manufacture for personal use be marked with your name, city, state, and serial number, though there's no federal requirement to register this information. New Hampshire doesn't impose additional marking requirements beyond federal standards.
The completed rifle must comply with federal regulations, meaning no select-fire capability without proper NFA paperwork and tax stamps. Standard semi-automatic AR-15 configurations are perfectly legal in New Hampshire. The state has no assault weapon ban, high-capacity magazine restrictions, or feature-based prohibitions that would limit your build options.
If you later decide to sell a personally manufactured firearm, federal law requires the sale go through an FFL dealer for the background check. You should verify current state and federal regulations before beginning any build project, as laws can change and interpretations may vary.
Build Impact
New Hampshire's permissive laws give you maximum flexibility in your AR-15 build without worrying about state-specific compliance issues. You can focus on the technical aspects of your build rather than navigating complex legal restrictions that exist in other states.
