CMMG GUARD MKGS Radial Delayed Blowback 9mm and 45 ACP PCC Custom Build Parts

Show Filters

Within this category you can find the key parts needed to build your own custom tailored Pistol Caliber Carbine utilizing the new patented CMMG Radial Delayed Blowback technology. The radial BCG and barrel components are what make up the heart of the MKG system and come in both 9mm and .45 ACP delayed combo kits. You can either use a dedicated MKG lower receiver that utilizes Glock magazines, or you can use an ARC PMAG to 9mm conversion kit and convert your standard AR lower receiver for your GUARD Delayed Blowback upper receiver.

Remember to use only the parts that CMMG recommends and guarantees to work for their GUARD Pistols or Rifles. There are many other parts throughout the store that can be used; however, the parts in this category come highly recommended by CMMG and/or individuals that have laid down some groundwork and tested certain components. Be sure to reach out to either us or CMMG if you have any questions regarding compatibility. RTB is always available to chat about your upcoming PCC build!
