The CMMG Banshee 9mm Luger 8" AR-platform pistol brings the handling and ergonomics of the AR ecosystem to a compact, magazine-fed 9mm platform built for shooters who want rifle-like controls in a tight package. This complete upper receiver group pairs CMMG's radial delayed blowback operating system with an 8-inch barrel to deliver carbine-level velocity and accuracy in a form factor that excels for home defense, close-quarters training, and tactical drills where standard pistol-caliber rifles feel oversized.
Built on a billet 6061-T6 aluminum upper receiver with an M-LOK free-float handguard, the Banshee offers genuine modularity: it works with standard AR-15 lower receivers and 9mm conversion magazines, or you can pair it with CMMG's purpose-built 9mm lowers to run your choice of magazine platform—Colt, Glock, or Sig P320 patterns. That flexibility means you can build around the magazines you already own or standardize across your kit. The included ZEROED linear compensator tames recoil impulse, while the ambidextrous charging handle and polymer dust cover come ready to shoot right out of the box.
At 3 pounds and 16.5 inches in total length, the Banshee pistol remains nimble in vehicles, tight spaces, or slung across your body. The 1:10 barrel twist is optimized for 9mm projectiles, and the Armor Black Cerakote finish resists corrosion without the weight penalty of heavier coatings. Whether you're running it as a standalone pistol or planning a future lower swap, the Banshee upper delivers the reliability and adaptability CMMG is known for.
| Caliber | 9mm Luger |
| Barrel Length | 8 inches |
| Barrel Twist | 1:10 |
| Barrel Contour | Medium Taper (MT) |
| Barrel Material | 4140CM Steel |
| Operating System | Radial Delayed Blowback |
| Upper Receiver | Billet 6061-T6 Aluminum |
| Handguard | CMMG EML7 M-LOK Free-Float |
| Charging Handle | CMMG ZEROED Ambidextrous |
| Muzzle Device | CMMG ZEROED Linear Compensator (1/2 x 28 threads) |
| Finish | Armor Black Cerakote |

The Banshee upper works with standard AR-15/Mk4 lower receivers using 9mm conversion magazines. CMMG also offers dedicated 9mm lowers: the Mk9 (for Colt-pattern magazines), MkGs (for Glock-pattern magazines), and Mk17 (for Sig P320 magazines). This flexibility lets you choose the magazine platform that fits your existing inventory or preferences.
This is a complete upper receiver group. It includes the bolt carrier group, charging handle, compensator, and dust cover. You'll need to pair it with an AR-15 compatible lower receiver to build a complete firearm.
The upper group comes ready to shoot with a ZEROED AR-15 polymer dust cover, ZEROED ambidextrous charging handle, and ZEROED linear compensator for 9mm already installed.
The 8-inch barrel delivers solid velocity for 9mm while keeping the overall package compact and maneuverable—ideal for close-quarters use, home defense, and tactical training where a shorter profile matters without sacrificing ballistic performance.
