The CMMG Banshee 33A030Cab Mk3 is a 12.5-inch 8.6 Blackout pistol built on CMMG's AR-10 scale Mk3 platform—a serious option for shooters who want modern rifle caliber power in a compact, maneuverable package. While traditional hunters might overlook the Banshee in this chambering, 8.6 BLK changes that calculus: it delivers subsonic and supersonic velocity options with the magazine capacity and modular ergonomics that AR builders expect. If you've built AR-15s before, CMMG's Mk3 ecosystem will feel instantly familiar, but scaled up to handle larger cartridges like .308 Win, 6.5 Creedmoor, and now 8.6 Blackout.
Built around a billet 7075 T6 aluminum upper and lower receiver, this Banshee runs a direct impingement system with a pinned adjustable gas block—letting you fine-tune reliability and recoil impulse whether you're running subs or hot loads. The 12.5-inch 4140 chrome-moly barrel features a 1:3 twist, optimized for the 8.6 BLK round, and wears a CMMG ZEROED linear compensator. The EML11 M-LOK handguard gives you full modularity for lights, braces, and accessories, while the CMMG RipBrace, ambi charging handle, and 60/90-degree safety selector keep controls ambidextrous and intuitive.
At 7.4 pounds and 29.5 inches overall, the Banshee strikes a balance between portability and shootability. It ships with a Magpul 20-round PMAG and runs the CMMG ZEROED single-stage drop-in trigger, so you're ready to run right out of the box. This is a rifle for serious builders and shooters who want the flexibility of the 8.6 platform without sacrificing the ergonomics and modularity that make AR-pattern guns so adaptable.
