CMMG 99A890FTI Banshee MKGS 5" 34-Round Threaded Barrel AR Pistol

The CMMG Banshee MKGS 5" 34-Round Threaded Barrel AR Pistol represents a purpose-built platform engineered for operators who demand compact firepower without compromise. This AR-pattern pistol bridges the gap between handgun accessibility and rifle capability, making it ideal for tactical professionals, home defense applications, and those seeking a maneuverable short-barreled system. The 5-inch threaded barrel configuration delivers the ballistic performance expected from modern intermediate cartridges while maintaining the handling characteristics necessary for confined spaces, vehicles, and dynamic engagement scenarios.

Built on CMMG's proven Banshee platform, this MKGS variant features a threaded muzzle that accommodates suppressors, flash hiders, and compensators for user-customization of ballistic characteristics and sound signature. The 5-inch barrel length optimizes velocity while maintaining a compact overall length of 13.5 inches, critical for CQB and vehicle-based operations. Weighing 8.8 pounds, the system achieves balance between recoil management and portability—heavier than a standard pistol but lighter than a carbine. The included 34-round magazine capacity provides substantial firepower reserves, essential for tactical applications where reload frequency directly impacts engagement effectiveness. The AR-pistol ergonomics—flat-top receiver configuration, modular trigger group, and Picatinny rail systems—enable rapid accessory integration and platform familiarity across law enforcement and military operators.

This platform excels for professionals requiring rapid deployment in confined environments, home defenders seeking magazine-fed rifle power in pistol form, and shooters building specialized short-barreled systems. The threaded barrel opens significant customization paths—suppressors reduce report and muzzle flash, compensators mitigate felt recoil and muzzle rise, and the modular AR architecture accepts industry-standard furniture and optics. Compatibility with standard AR-pattern magazines, triggers, and accessories ensures this system integrates seamlessly into existing tactical inventories. Before purchase, verify local and federal regulations regarding AR pistols, threaded-barrel ownership, and suppressor legality in your jurisdiction.
