Shipping and FFL

This product is an 80% frame and does not require transfer through a Federal Firearms License (FFL) dealer at the time of purchase.

At that point, you are required to comply with all applicable federal, state, and local laws regarding possession and use. It is your responsibility to verify that your intended build and final product are legal in your jurisdiction. Polymer80 and this retailer do not provide legal advice, and you should consult with qualified legal counsel if you have any questions about your specific situation.
