Shipping & FFL

We offer very fast shipping on all 80 percent lowers and 80% lowers. Orders placed before 2 PM EST ship the same business day. Because this product is an unfinished receiver, it does not require transfer through a Federal Firearms License (FFL) holder. However, you are responsible for verifying that the purchase and manufacture of an 80 percent lower is legal in your jurisdiction. FFL Transfer Disclaimer: This 80% lower is not a firearm and does not require an FFL for shipment. Once you complete the machining process, you become the manufacturer and must comply with all applicable federal, state, and local laws, including any restrictions on unserialized firearms. We recommend consulting legal counsel if you are uncertain about the legality of manufacturing an 80 percent lower in your area. Very fast shipping is standard on all 80% lowers, but final compliance is your responsibility.
