CMMG has upped its game when it comes to pistol-caliber ARs with the introduction of the MkGs Guard, a platform chambered for one of the most popular rounds of all time, featuring the company’s innovative delayed blowback operation.

What makes the new MkGs Guard exciting?

  • The MkGs Guard is the newest addition to the line introduced earlier this year.
  • This version is chambered in the ever-popular 9mm.
  • Like the .45 ACP iteration, this features CMMG’s Radial Delayed Blowback system.
  • This ensures smooth, reliable cycling, and can reduce weight by as much as 6.5 ounces.
  • There are two pistol and four rifle models of the new MkGs GUARD.
    mkg-guard-first - MkGs Guard 9mmThe Missouri AR manufacturer is downright innovative in its approach to black rifles. Whether you’re talking its monstrous AR-AK hybrid MK47 Mutant or its deadly accurate Mk3 in 6.5 Creedmoor, the company most definitely isn’t a spitting out your run-of-the-mill tactical arms.This is no more apparent than in CMMG’s vast selection of pistol-caliber ARs, which come in nearly every conceivable size and configuration. And the gunmaker has slapped another potential gem in its catalog, chambering one of its newest designs in one of the most popular pistol calibers out there.Freshly released, the MkGs Guard in 9mm is decked out with one of CMMG’s newest pieces of technology — its Radial Delayed Blowback operating system. Released earlier this year in the form of the MkG-45 Guard, and originally invented to provide a nimbler operating system that reliably cycled the .45 ACP, the design is elegant in its simplicity.unnamedThe Guard’s Radial Delayed Blowback system uses a bolt carrier group (BCG) similar to those on a standard, direct impingement AR. Except, the system has been tweaked so the bolt is forced to rotate after the shot to unlock, in turn slowing down the BCG. This simple design modification allows the system to cycle smoothly and reliably, even larger-caliber pistol rounds, without turning to the bulky material required to make a traditional blowback system functional.Shooters reap the benefits in the form of a lighter overall platform — as much as 6.5 ounces vs. a straight blowback pistol-caliber AR. On top that, it makes for a firearm with a lighter recoil and overall more controllability. Given the system was originally conceived for the .45 ACP, it’s a sure bet the MkGs GUARD will be a pussy cat shooting the smaller 9mm, whether for self-defense, competition or just plinking around.mkg-guard-second - MkGs Guard 9mmGetting up to speed on the 9mm MkGs Guard is a snap, as CMMG has ensured the six pistol and rifle configurations all have fully functional AR-15 controls. This includes last-round hold open, as well as the magazine release and safety both being where you’d expect.The MkGs Guard also features newly designed dual-pinned, fully machined bolt catch linkages that ensure reliable operations straight out of the box, with no adjustments required. The pistols and rifles are both compatible with Glock magazines, with each model shipping with a 33-round magazine. Additionally, the muzzle of each model has a ½-36 pattern for the addition of a suppressor or other muzzle device. And CMMG offers bolt weight kits separately for those shooting to fine-tune their Guard for use with a suppressor.Presently, CMMG’s MkGs Guards have MSRPs running from $1,299 to $1,599. But for those aiming to rock one of the smoothest shooting pistol-caliber ARs out there, the price might just be right.
