Every Model, Every Caliber.
CMMG (formerly Central Missouri Machine Guns) was founded in 2002 in Boonville, Missouri. Originally a small-batch AR-15 builder, CMMG has expanded to multi-caliber AR platforms, the Banshee PCC family, and the MkG GUARD series. The Mk57 in 5.7x28mm and the Banshee .22 LR and pistol-caliber carbines are top-sellers. CMMG was an early adopter of the Radial Delayed Blowback action used in their PCCs.

CMMG Value FAQ
What's special about the Banshee?
Banshee is CMMG's compact PCC platform — pistol or short-barreled rifle (SBR) configurations using the Radial Delayed Blowback action. The Mk57 in 5.7x28mm is particularly popular for offering high-velocity defensive cartridge in a compact form factor. Banshees are among the best-selling PCCs by unit volume.
What is the Radial Delayed Blowback action?
CMMG's proprietary delayed blowback system that uses cam-action rollers in the bolt carrier to delay opening. Produces softer recoil than simple blowback PCCs and runs cleaner. Standard on all CMMG PCCs.
Is the Mk47 Mutant a real AK or an AR?
It's an AR — the Mk47 takes standard AK magazines but uses an AR-pattern lower receiver and trigger. The 'Mutant' name reflects the hybrid design. It bridges the AK ammunition supply (cheap 7.62x39) with the AR ergonomics.
