These AR9 compatible upper components were part of a modular prototype that never really caught on. That means you get a great deal on the bits left over. We will be giving out a 3d printable model that will fit the section milled out as soon as its ready. With a little creativity you can design whatever you want to put there.
- Compatible with all standard AR-15 / AR-9 components and most aftermarket parts
- Save money by building your own AR-9 rifle or pistol from the ground up exactly the way you want it configured
