CMMG Banshee Mk4 5.56mm | 10.5″ 30rd | Black

The CMMG Banshee Mk4 is a compact AR-pattern pistol chambered for 223 REM/5.56 NATO with a 10.5″ barrel and a 30-round magazine capacity. Built on the Mk4 lower, it pairs a lightweight aluminum frame with polymer furniture and an EML9 M-LOK handguard to keep bulk and weight low for carry in a pack or vehicle. The pistol ships with a single magazine, a zeroed CMMG trigger and a pistol tube stock configuration. For optics, a robust red-dot such as an Aimpoint PRO (or an equivalent duty-grade reflex sight under $1,000) is a practical match for this platform and its Picatinny footprint.
