The CMMG Banshee Mk3 in 8.6 Blackout establishes a new benchmark for compact, high-impact firearm platforms. While not traditionally associated with a 12.5-inch barrel, the 8.6 BLK chambering transforms this Banshee into an exceptionally potent tool, demonstrating significant terminal effect suitable for specific hunting applications and close-quarters defense.
CMMG engineers the Mk3 platform for larger calibers such as .308 WIN, 6.5 Creedmoor, and this 8.6 Blackout variant. This robust architecture is based on the LR-308/DPMS Gen 1 high-pattern design, ensuring a foundation of durability and component interchangeability within the AR-10 ecosystem.
Key Features
Caliber Integration
Chambered in 8.6 Blackout, this Banshee Mk3 is optimized for substantial energy transfer. The cartridge’s design, combined with the 12.5-inch barrel, facilitates a compact system that still delivers considerable terminal performance, expanding its utility beyond conventional expectations for its size class.
Platform Architecture
Utilizing the Mk3 (AR-10) sized platform, this firearm provides the structural integrity necessary for larger calibers. Its adherence to the LR-308/DPMS Gen 1 high-pattern design ensures a consistent interface with a broad range of compatible components, enhancing its inherent modularity for specialized configurations.
Construction & Materials
The Banshee Mk3 features receivers precision-machined from 7075-T6 aluminum, known for its high strength-to-weight ratio. The entire assembly, including the barrel, receives a durable Black Nitride finish, providing enhanced corrosion resistance and surface hardness for extended operational life.
Ergonomics & Accessory Integration
Equipped with an 11-inch CMMG EML M-LOK handguard, this platform offers extensive accessory mounting flexibility. Full-length M-LOK slots are integrated on both sides, the bottom, and strategically placed between the top Picatinny rail sections. The CMMG Zeroed Grip enhances shooter interface and control, contributing to improved weapon manipulation. As a hallmark of the Banshee series, the design incorporates stylized receivers that do not compromise function.
Compact Form Factor
The 12.5-inch barrel length is critical for maneuverability in confined environments. Configured as an AR Pistol, the Banshee series is often deployed with a quick-deploying RIPBRACE, leveraging a compact profile for rapid deployment and enhanced stability. This design prioritizes handling without sacrificing operational capability.
