CMMG Banshee MKGs .40 S&W 8″ Pistol — Armor Black
$1,884.34
The CMMG Banshee MKGs .40 S&W 8″ Pistol — Armor Black uses radial delayed blowback for smooth, low-recoil shooting. It comes with an 8″ threaded barrel, linear compensator, ambidextrous controls, and accepts Glock-pattern .40 S&W magazines. Ready for home defense, range use, or suppressor mounting right out of the box.
The CMMG Banshee MKGs .40 S&W 8″ Pistol — Armor Black brings radial delayed blowback technology into a compact, ambidextrous AR-style pistol. It uses the same proven operating system that reduces felt recoil and keeps the action smooth, even with hotter .40 S&W loads. This package ships with a 7″ EML M-LOK handguard, a Zeroed linear compensator, and a threaded barrel, so you can mount a suppressor or muzzle device right out of the box. It accepts small-frame Glock-pattern magazines, and one 22-round magazine is included.

Key Features
- Radial Delayed Blowback System — Why it matters: This system slows the bolt just enough to keep the action smooth and reliable, reducing felt recoil by roughly 30% compared to direct blowback. That means less muzzle rise and faster follow-up shots, especially important for newer shooters.
- Ambidextrous Zeroed Controls — Why it matters: Safety, bolt catch, and magazine release are all ambi, so left-handed or right-handed shooters can run the gun without changing grip or breaking position. Great for teaching a family member who shoots opposite-handed.
- 8″ Medium-Taper Threaded Barrel with Linear Compensator — Why it matters: The 1/2×28 threads let you attach a suppressor or flash hider, while the included compensator directs blast forward, keeping noise and concussion away from the shooter and anyone next to you.
- 7″ EML M-LOK Handguard — Why it matters: The slim, free-float handguard gives you a solid grip surface and plenty of M-LOK slots for a light, laser, or bipod. No tools needed to swap accessories.
- Glock-Pattern Magazine Compatibility — Why it matters: Uses the same magazines as your Glock 22, 23, or 27. One magazine system for pistol and carbine means fewer things to track at the range or in a home-defense scenario.
Who It’s For
This pistol is built for the shooter who wants a compact, low-recoil platform that handles like an AR but feeds from common Glock magazines. It’s a strong choice for home defense, range practice, or as a truck gun. The ambi controls and softer recoil make it especially friendly for new shooters and youth shooters who are ready to step up from a .22 but aren’t ready for a full-power .223 or 9mm with a heavy spring.
Pros & Cons
- Pro: Radial delayed blowback keeps the action smooth and reduces recoil noticeably — even with .40 S&W.
- Pro: Ambidextrous controls let lefties and righties shoot it comfortably without modification.
- Pro: Threaded barrel with compensator is ready for a suppressor right out of the box.
- Con: .40 S&W ammunition is slightly more expensive than 9mm, and magazine options are limited to Glock-pattern .40 mags (not all Glock 9mm mags work).

FAQ
Does this pistol come with a brace or a buffer tube?
No, the CMMG Banshee MKGs ships with a standard AR-style buffer tube but does not include a brace or stock. You can add a brace or run it as a pistol configuration with a buffer tube cover. Check local laws before adding a brace.
What brand of magazines does it accept?
It accepts small-frame Glock-pattern magazines chambered in .40 S&W. One Glock 22-round magazine is included. You can also use Glock 23 and Glock 27 magazines with the proper adapter or if they are .40 S&W.
Is the barrel threaded? What thread pitch?
Yes, the barrel is threaded with a standard 1/2×28 thread pitch. It includes a CMMG Zeroed linear compensator. You can remove the compensator and attach a suppressor, flash hider, or other muzzle device.
Can I use this for home defense?
Yes. The compact 8″ barrel makes it easy to maneuver in tight spaces, and the radial delayed blowback system keeps recoil manageable. With a quality light and proper ammunition, it’s a solid home-defense platform.
Is this legal in all states?
Because it’s classified as a pistol, it is legal in most states that allow AR-style pistols. However, some states have magazine capacity limits or specific requirements for threaded barrels. Check your local laws before ordering.
