Compliance with federal and state regulations is a defining theme around any 80% project, and polymers80.us.com makes the framework as clear as possible for customers approaching this category for the first time. Under federal law, an 80% receiver is not classified as a firearm at the time of sale because it has not been completed to the legal threshold; once a builder finishes the receiver, additional rules concerning serialization, marking and ownership may apply depending on the state of residence. polymers80.us.com encourages customers to confirm the requirements that apply where they live, including any state-level provisions on serialized frames, registration and disposal of finished firearms. The product descriptions provide context about the stage of completion of each receiver and reference the regulatory categories that the buyer should be aware of. By framing the product information in this way, polymers80.us.com helps hobbyists move forward with builds while remaining attentive to the legal context surrounding the platform.
