Can I Build an AR-15 in Massachusetts?

Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.

Quick Answer

Building an AR-15 in Massachusetts is heavily restricted and generally not advisable due to the state's assault weapon ban. Most standard AR-15 configurations are prohibited under Massachusetts law.

What This Means for You

Massachusetts has some of the strictest assault weapon laws in the country, and the AR-15 platform typically falls under these restrictions. The state's enforcement guidance has made it clear that most AR-15 variants are considered assault weapons. Even if you could theoretically build a compliant version, the legal risks and complexity make it impractical for most builders.

The Detail

Massachusetts defines assault weapons through a combination of features and specific model designations, and the AR-15 platform is specifically mentioned in the state's prohibited weapons list. The state's 2016 enforcement notice clarified that firearms substantially similar to the AR-15 are also prohibited, which covers most AR-style rifles regardless of specific features.

Even attempting to build a feature-compliant version presents significant legal challenges. Massachusetts law focuses not just on specific features like pistol grips or collapsible stocks, but on the overall design and function of the firearm. This makes it extremely difficult to create a truly compliant AR-15 style rifle.

The state also requires proper licensing for any firearm construction, and you would need an appropriate firearms license before even attempting any build. Additionally, Massachusetts has specific laws about firearm manufacturing that could apply to home builds, adding another layer of legal complexity.

Given the legal landscape, most firearms enthusiasts in Massachusetts focus on other rifle platforms that are more clearly compliant with state law. The risks associated with attempting an AR-15 build generally outweigh any potential benefits.
