CMMG 99A290F-AB BANSHEE MKGS 5" Pistol

The CMMG 99A290F-AB BANSHEE MKGS 5" Pistol represents a modern evolution in AR-platform pistol design, purpose-built for operators who demand reliability in confined environments. This 9mm AR pistol merges the ergonomics and modularity of the AR platform with the compact footprint necessary for vehicle operations, close-quarters training, and home defense. Developed for both law enforcement and civilian operators, the BANSHEE MKGS delivers the firepower of a rifle with handling characteristics closer to a traditional pistol, making it an ideal choice for those seeking a versatile, short-barreled platform.

At 13.5 inches overall length with a 5-inch barrel, this platform balances shootability with portability without the legal complexity of short-barreled rifle restrictions when properly configured. The MKGS designation indicates CMMG's modern generation platform with improved ergonomics and control accessibility, allowing ambidextrous operation without compromising trigger geometry or grip texture. The 9mm chambering provides a low-recoil, high-capacity alternative that's easier to manage in rapid engagement sequences while maintaining adequate terminal ballistics for defensive applications. Weighing 9.7 pounds fully assembled, the system delivers a natural point-of-aim that reduces fatigue during extended training or duty carry, with the modular AR design enabling caliber flexibility and component customization for mission-specific requirements.

Law enforcement agencies and tactical teams value the BANSHEE MKGS for backup weapon roles, specialized unit work, and training environments where AR ergonomics benefit operators already familiar with rifle platforms. Civilian shooters benefit from the standardized AR control layout, allowing them to leverage existing knowledge and reduce training curves. The platform accepts standard AR-15 upper and lower parts, enabling accessory mounting for optics, lights, and rail systems through conventional Picatinny interfaces. Whether used as a home defense tool, range training platform, or specialized duty weapon, the CMMG BANSHEE MKGS integrates seamlessly into existing AR ecosystems while providing the compact profile demanded by real-world tactical application.
