Bill > S1361

This bill aims to regulate the manufacturing and assembly of 3D printed firearms and "ghost guns" (firearms without serial numbers) in Massachusetts. Key provisions include: 1. Defining "assembly" as the fitting together of firearm components to construct a firearm, and "manufacture" as newly fabricating or constructing a firearm. 2. Defining "unfinished receiver or firearm frame" as a piece of material that has been shaped or formed to become the frame or receiver of a firearm, but excluding pieces altered for transportation or storage. 3. Requiring individuals who manufacture or assemble a firearm to obtain a unique serial number from the state and engrave it on the firearm. 4. Prohibiting the use of 3D printing to manufacture any firearm or firearm part unless the person has a federal license to manufacture firearms. 5. Requiring firearms made from polymer plastic to have at least 3.7 ounces of stainless steel embedded in the plastic and be engraved with a unique serial number. 6. Establishing penalties of up to 10 years in prison and a $10,000 fine for violating these provisions.
