AR9 Pistol Kit

AR9 Pistol Kit

With how popular our new 9mm AR9 80% lower has become, we decided to part together some high-speed AR9 Pistol Build Kits to make your build even easier. Our 9mm kits are carefully configured to provide MOA accuracy. Each kit can be purchased with an optional A9 80% lower to complete your build with one order. To provide the most customization and performance, our AR-9 Kits are designed to operate using 9mm Glock magazines. If using our 9mm lower to complete your pistol, no 9mm AR magazine conversion block is required.
