Description
This AR-9 Pistol Build Kit is the key to gaining optimal supersonic 9mm velocity while retaining the shortest possible pistol configuration. With this kit, you can build a compact, lightweight 9mm AR pistol capable of accurately hitting medium-range targets. Thanks to the included hybrid 9mm G-9 bolt carrier group, this pistol kit accepts both factory and aftermarket 9mm Glock magazines. Blowback operation negates any gas block or tube, making for an utterly reliable pistol upper.
What’s Included
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with pistol brace. 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.
Here's the beginner's guide to 80% lowers.

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.
