Buy Now Starter Guide

The Ghost Gunner 3 Zero Percent kit allows you to mill a complete, mil-spec and unregistered AR-15 receiver from an unformed block of aluminum - from 0%. Just like our 80% kits, this is performed automatically using our Ghost Gunner 3 CNC mill, meaning that you can make a AR-00 today, no machining experience necessary, in the privacy of your own home.

After milling the non-receiver block on the Ghost Gunner 3, your new zero percent receiver is combined with a lower-lower and buffer tower (available for sale or DIY) to complete your AR-00 receiver, which is now ready to be assembled into a full AR just like any other stripped lower.

In 2022, the ATF will attempt to ban the purchase of unserialized 80% lowers. At that time, Ghost Gunner's zero percent receiver will become the only legal and affordable method of making an unregistered metal lower. The age of 80% is ending. The age of zero has begun.

Made from 6061 aluminum

No machining experience required

Equivalent to milspec stripped lower

AR-00 FAQs

In 2022, ATF will attempt to redefine 80% lowers and the most popular 80% build kits as “firearms” under federal law. This regulation will make 80% lowers de facto illegal to buy and sell online, and so most manufacturers of lowers and fixtures will either go to court or out of business.

But Ghost Gunner is a unique platform which is not limited by the new rules.

Ghost Gunner 3 Zero Percent kits and components allow you to make the same kinds of complete, mil-spec and unregistered AR-15 receivers you have come to expect from traditional 80% blanks, only now you start from an unformed block of aluminum—from 0%.

With our Zero Percent non-receiver blocks, Starter kits and lower build kits, you can continue to easily make your own legally unregistered firearms in the comfort of home. GG3 Zero Percent components are made in the USA.

CNC machining and 3D printing will soon be the only ways to make totally private firearms in the US, unless you become a professional machine shop. The Ghost Gunner platform and its Zero Percent concept were developed by Defense Distributed: the inventors of desktop CNC gunsmithing and 3D printed firearms. Our products are made for long-term success and support, and to stand up to any level of federal scrutiny.

  • NO FFL or background check required
  • No experience necessary. GG3’s DDCut software provides easy-to-follow instructions and sets you up for seamless facing, cutting and drilling of your receiver. Ideal for beginners.
  • Future-proofed value. Our platform has lasted for years and cannot be regulated away.
  • Only legal and affordable method for unregistered metal lowers in 2022 and beyond
  • Assured production quality. Metal zero percent receivers are made to military spec and will outlast printed receivers by decades.
  • American-Made

Zero percents may seem like novel technology, but they’re nothing new legally speaking. Under federal law, neither the Ghost Gunner CNC mill, nor any of its zero percent fixtures or build kit components can be considered firearms. Therefore no federal license is required to purchase or begin working with zero percent components.

The AR-15 is a modular rifle, and so we’ve simply extended the rifle’s modularity while complying with the ATF’s new layer of illegal, unconstitutional rules. Zero percent builds start with a block of aluminum or plastic stock material, and are supplemented with unregulated, bolt-on components.

The debut AR-type Zero percent build from Ghost Gunner is made of three parts:

  1. An upper lower
  2. A lower lower
  3. A buffer tower

Each of these components may be made separately at home or on the GG3 platform, but we recommend making only the “upper lower” and building the rest of your lower out from a kit.

Can’t decide where or how to start? We offer the nation’s first and best home platform for learning how to make, serialize, engrave and skeletonize receivers and their related components. Hobbyists, professionals, businesses and private individuals enjoy our industry-defining technologies for their own purposes, and we support them all.
