CMMG Banshee Mk4 9mm 6.5" Suppressor-Ready Rifle

The CMMG Banshee Mk4: Purpose-Built for Suppressed 9mm Shooting

The Banshee Mk4 represents a thoughtful approach to modern rifle design. Chambered in 9mm Luger, this platform is specifically engineered to excel when paired with a suppressor—delivering the quiet, controllable shooting experience that discerning riflemen demand.

Operating System & Reliability

At the heart of the Banshee lies CMMG's Fixed Ejector Radial Delayed Blowback system. This operating principle is fundamentally different from traditional direct impingement designs. The radial delayed blowback mechanism provides reliable function across a wide range of ammunition types and suppressor configurations, making it an excellent choice for shooters who demand consistency.

Ergonomics & Controls

The Banshee Mk4 features fully ambidextrous controls throughout:

• Ambi charging handle for left and right-handed shooters
• 60/90 ambidextrous safety selector for intuitive operation
• Single-stage drop-in trigger for clean, predictable breaks
• Ambidextrous pistol grip for natural hand positioning

Practical Design Features

• 6.5" threaded barrel ready for suppressor mounting
• Black Nitride finish for durability and corrosion resistance
• Picatinny rail for optic mounting flexibility
• M-LOK handguard with included silicone covers for comfortable shooting in any condition
• Standard AR15 magwell for compatibility with common magazines
• 33-round magazine included, with 10-round options available

What You Get

This rifle arrives ready to shoot, complete with a 33-round CMMG magazine and silicone handguard covers that attach securely to the M-LOK slots. Position them as needed to keep your hands comfortable during extended shooting sessions.

The Banshee Mk4 is an honest rifle built for shooters who understand that suppressed shooting isn't a luxury—it's smart shooting.
