It does not include the component to make a firearm: A stripped lower receiver. Pair this rifle kit with an AR-15 80% lower receiver and AR-15 jig to fabricate a receiver, sold separately.

No FFL or serialization is required to fabricate a receiver under federal law. However, state laws vary. Some states require serialization or have banned 80% lowers and gun-making kits. We encourage each and every builder to perform their own research about the state and federal laws that apply to them.
