CMMG Releases the MkGs GUARD chambered in 9mm.

Boonville, MO – Meet CMMG’s new MkGs GUARD in 9mm. The GUARD is a pistol caliber carbine (PCC) AR15 that is fed from 33-round factory Glock magazines and runs on CMMG’s patent pending Radial Delayed Blowback operating system. An incredibly smooth shooter, the new GUARD in 9mm is a great option for home defense, PCC competition, or as a plinker to bring to the range.

The feature that sets the GUARD apart from the competition is the unique Radial Delayed Blowback operating system.

CMMG first invented Radial Delayed Blowback to reliably chamber .45 ACP, which was the first caliber introduced in the GUARD platform earlier this year. The recoil impulse of .45 ACP called for a new operating system that would compensate for the sizable recoil impulse without adding additional weight to the carrier and buffer. Straight blowback was not the solution and so Radial Delayed Blowback was born.

Now, when using the same Radial Delayed Blowback operating system to chamber 9mm, CMMG’s newest version of the GUARD boasts a lighter buffer and bolt carrier group than other 9mm PCC’s that use a straight blowback system. The combined difference in weight of the BCG and buffer when comparing straight blowback versus Radial Delayed Blowback can be as much as 6.5 ounces.

This reduction in reciprocating mass on the CMMG GUARD makes it a smoother shooting firearm, and makes it easier to keep follow-up shots on target. Whether using the GUARD for home defense or for competition, fast and accurate follow-up shots can determine success or failure.

CMMG also put a high emphasis on having fully functional AR15 controls, including last round hold open. The GUARD features an all-new patent pending dual-pinned, fully machined bolt catch linkage. This linkage provides consistent and reliable operation straight out of the box with no need for adjustments or fine tuning. The actuation from this linkage is robust enough that it still uses a standard bolt catch spring.

The MkGs GUARD comes with one 33-round factory Glock magazine. Bolt weight kits will be sold separately for those who wish to fine-tune the GUARD for suppressor usage.
