Shipping & FFL

Because this is an 80% frame, it is not classified as a firearm under federal law. It ships directly to your door with no FFL transfer required. However, you must comply with all applicable federal, state, and local laws regarding the completion and ownership of homemade firearms. It is your responsibility to verify that you are legally allowed to own and build this product in your jurisdiction. Once completed, the frame becomes a firearm and may be subject to additional regulations. We recommend consulting an attorney if you have any legal questions before purchasing.
