The CMMG Banshee 5.7x28mm 5" AR-platform pistol brings a modern, compact defense round to the AR ecosystem with genuine shootability. If you're exploring 5.7x28 as a personal defense caliber, this upper builds on the platform's reputation for flat trajectory and manageable recoil—qualities that matter in a close-quarters context. The 5" barrel keeps overall length down to a compact 13.8", making the Banshee CMMG's most condensed 5.7x28 offering while the radial delayed blowback operating system cycles the round reliably. The Armor Black Cerakote finish and M-LOK free-float handguard give it a clean, tactical appearance that works as hard as it looks.
Built on a billet 6061 T6 aluminum upper receiver, the Banshee ships complete with essentials: a bolt carrier group, CMMG ZEROED linear compensator (1/2 x 28 thread), ambi charging handle, and polymer dust cover. That means you're not hunting for parts before you shoot. The 1:9 barrel twist and 4140CM SBN steel barrel are engineered for the round, and the CMMG EML4 M-LOK rail gives you mounting flexibility for lights, lasers, or other mission-specific accessories. At 2.5 lbs, it's genuinely lightweight without sacrificing rigidity.
Compatibility is straightforward: pair it with a CMMG Mk57 lower for a complete 5.7x28 build, or run it on a standard AR-15/Mk4 lower using 5.7 AR conversion magazines. That flexibility lets you adapt to your existing platform or start fresh. Whether you're a 5.7x28 enthusiast, a defensive-minded shooter, or someone curious about the round's capabilities, the Banshee delivers the core CMMG reliability in a compact, well-finished package.
