CMMG Banshee MK4 9mm | 5″ M-LOK | 30rd | 94AD90F-AB

The CMMG Banshee MK4 is a compact 9mm AR-pattern pistol built on the Mk4 platform with a 5-inch threaded barrel, RipBrace, and CMMG EML4 M-LOK handguard. It uses CMMG 9ARC 30-round magazines and operates with a fixed-ejector radial-delayed blowback system. The pistol combines billet and forged aluminum receivers with a Cerakote Armor Black finish for durable, low-profile carry. For an optic that complements the platform without exceeding $1000, a compact reflex sight such as the Trijicon MRO pairs well for fast target acquisition.
