CMMG announced three new rifles in the newly introduced Mk47 line: the Mk47 Mutant T, Mutant AKM and Mutant AKM2. These are AR-style rifles chambered for the 7.62×39 that accept standard AK-47 magazines.
The base model is the Mutant T, while the AKM and AKM2 offer varying upgrades. Let’s run down the basics of these rifles and take a look at some of the upgrades in the line.

Operation & Bolt Carrier Group
Like other AR-style rifles, the Mk47 is a direct gas impingement gun. It uses a carbine length gas system.
The Mk47 uses a modified AR-10 bolt for strength. The BCG has been reduced to a length of only 8″, but retains all of the thickness and durability of the AR-10 bolt face.
Magazines
CMMG ships all of these rifles with the relatively new Magpul AK-type PMAGs. One 30-round magazine ships with each gun.
The rifles use an AK-style latch system for magazine retention. While not as handy as a push-button style mag release, it helps ensure that all of the existing AK-47 magazines should work in these rifles.
So, if you have a stockpile of surplus ComBloc mags or a case of the ridiculously cheap Tapco mags you will be set. Additional Magpul magazines are available for less than $14 apiece at full retail.
Barrels
All three versions of the gun use a 16.1″ barrel with a 1:10 twist. The barrel has a medium taper profile and is free floated.
The base Mutant T model comes equipped with an A2-style compensator. A CMMG SV brake is used on both the AKM and AKM2 models.
Handguard
KeyMod is the name of the game in many of the new AR-style rifles hitting the market. The Mk47 rifles are no different.
All three rifles come with a CMMG RKM15 KeyMod handguard. These are thin units that offer a lot of ventilation for the barrel. The rails are made of 6061-T6 aluminum. They offer a lot of mounting points for KeyMod accessories and Picatinny rail lengths.
Sights
No sights ship with these rifles. I would hope that the guns would come with MBUS sights (or something similar,) but they do not. While many people will want to add a red-dot type optic, iron sights are always appreciated.

According to CMMG, the following parts are interchangeable with any MilSpec/non-ArmaLite parts:

Love the BCG! I would NEVER personally own a 7.62×39 AR-15… Until not.. Well technically MK-47 not AR15 but the Bolt Face is beefy and not as worried as I was before with the Bolt failing.
