CMMG BANSHEE MK10 10mm AR Pistol, 8-Inch Barrel

Description

The Banshee MK10 is CMMG’s answer to a specific question: what happens when you take the 10mm Auto cartridge—a round that already sits at the upper end of handgun ballistics—and build a compact AR-platform pistol around it? The result is a package suited to the shooter who wants meaningful terminal performance in a short, maneuverable form factor, whether for home defense, range work, or as a truck gun.

CMMG’s Radial Delayed Blowback operating system is central to why this pistol handles 10mm as well as it does. Rather than a straight blowback design—which would require a heavy bolt and buffer to manage the cartridge’s pressure curve—the radial delayed system uses the bolt’s rotation against angled cuts in the barrel extension to delay the opening of the breech. This slows the rearward impulse and distributes felt recoil more gradually, which matters considerably with a cartridge generating this much chamber pressure in a pistol-length package. The practical effect is a more controllable shooting experience and reduced stress on the action over time.

The 8-inch barrel keeps the platform compact while still extracting more velocity from the 10mm case than a conventional handgun barrel would. The pistol ships with a 30-round magazine, giving the shooter meaningful capacity without a reload. An Armor Black finish and manual safety round out the package. The threaded muzzle—confirmed across multiple verified listings—allows for the attachment of a compensator or suppressor, though the specific thread pitch should be confirmed before purchasing any accessory.
