CMMG Zeroed Banshee Mk4, 5.7x28mm, 6.5" Barrel, 1- 32rd Magazine, OD Green, Suppressed Pistol

CMMG Suppressed ZEROED Banshee Mk4 5.7x28mm 6.5" Pistol

Experience one of the softest-shooting, most compact PDW platforms available. The CMMG Suppressed ZEROED Banshee Mk4 in 5.7x28mm pairs the exceptionally smooth Radial Delayed Blowback operating system with a factory-installed ZEROED suppressor that tucks neatly inside the oversized M-LOK handguard. With a 6.5" barrel, this pistol delivers flat-shooting 5.7x28mm performance in a highly controllable, suppressor-ready package.

Why the ZEROED Banshee Mk4 5.7 Stands Out

5.7x28mm has become one of the most popular personal defense cartridges thanks to its light recoil, high velocity, and effective terminal performance. CMMG’s Radial Delayed Blowback system makes this Banshee exceptionally smooth, while the factory ZEROED suppressor and oversized handguard create a clean, tucked, low-profile suppressed PDW.

The combination of the 6.5" barrel, premium ambi controls, and lifetime quality guarantee makes this one of the most refined compact 5.7 platforms available.
