9mm AR9 Pistol Kit

9mm AR9 Pistol Kit

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. 

Make your first build easy with our Ultimate AR9 Pistol Guide.

What's Included

  • Assembled/barreled 9mm AR upper
  • G-9 Hybrid 9mm bolt carrier group
  • High-quality CMV or SS pistol barrel
  • 9mm AR lower parts kit
  • 9mm AR buffer assembly

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.

Completing Your AR9 Pistol

 To complete your 9mm pistol build, you will need to purchase a billet AR9 80% lower. Fabricating the lower requires basic tools and can be done with one of our AR9 80% jigs, which include the necessary bits.
