The 8.6 Blackout was built from the ground up to perform out of short barrels, and the CMMG Banshee Mk3 is exactly the kind of platform it was made for. That lightning-fast 1:3 twist rate spins bullets hard enough to get impressive terminal performance whether you are pushing supersonic hunting loads or heavy subsonics behind a can. CMMG chambered it in a 12.5 inch 4140CM barrel with a black nitride finish, threaded 5/8×24 and capped with their ZEROED linear compensator, which sends blast forward instead of back at you. It is a smart setup for a big-bore pistol like this one.
Because 8.6 Blackout runs on a .308 case, the Banshee here is built on CMMG's Mk3 chassis, their AR-10 size platform patterned after the DPMS Gen 1 LR-308 design. Receivers are machined from billet 7075-T6 aluminum and wear a Cerakote Armor Black finish, and the whole package comes in at 29.5 inches overall. The direct impingement gas system pairs with an adjustable gas block, so you can tune it for suppressed subsonic work or full-power supersonic loads without drama. The 8.6 also feeds from standard .308 magazines, and CMMG includes a 20 round Magpul PMAG to get you started.
The EML11 M-LOK handguard gives you 11 inches of real estate with full-length M-LOK slots on the sides and bottom, plus M-LOK sections between the top Picatinny rail segments for lights, lasers, or a hand stop. Controls are handled by CMMG's ZEROED parts, including an ambidextrous safety and a crisp drop-in trigger, and the quick-deploying RipBrace extends with a simple pull. The flat top is optics ready, so mount a red dot or LPVO and go. Whether you want a compact hog and deer setup or a suppressor host that hits well above its size, this Banshee makes a strong case for itself, and CMMG backs it with their lifetime quality guarantee.
It runs standard, unmodified .308 Winchester pattern magazines like Magpul SR-25 style PMAGs, with no loss in capacity. One 20-round Magpul PMAG comes in the box, so you are ready to load up on day one.
Yes. The 12.5 inch barrel is threaded 5/8×24 under the included ZEROED linear compensator, and the adjustable gas block lets you tune the gun for suppressed use. Pair it with heavy subsonic loads and a can and it becomes an extremely quiet big-bore setup.
It does, and that is the whole point of the cartridge. The 1:3 twist rate spins bullets fast enough to deliver strong terminal performance from short barrels, something traditional .30 caliber rounds struggle with. Supersonic loads make this a legitimate compact hunting option for hogs and deer-sized game.
No, it ships optics ready with a flat top Picatinny rail and no iron sights. Most owners run a red dot or a low power variable optic depending on how they plan to use it. The full-length top rail gives you plenty of room for whatever you mount.
