With how popular our billet 9mm lower has become, we decided to part together some high-speed AR9 Pistol Build Kits to make your project even easier. Our 9mm kits are carefully configured to provide MOA accuracy. To provide the most customization and performance, our AR9 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.
NOTE: The 9mm cartridge operates using blowback and does not require the AR's typical gas system. As such, our AR9 Pistol Kits do not include a gas block or gas tube. The G-9 bolt is modified to operate inside the standard AR-15 stripped upper receiver without a gas key required.
To complete your 9mm pistol build, you will need to purchase a billet AR9 80% lower.
Your AR9 pistol build awaits.
