CMMG MK47: It’s Still The Mutant To Me – Video Review
by Tim Potter
U.S.A. This is the CMMG MK47, sometimes affectionately knows as the Mutant. This rifle really shook up the AR-15 and AK-47 world 5 years ago when it initially launched, and it also undoubtedly put CMMG on the map and cemented them as a major player in the AR-15 world. It started the trend at CMMG to adapt probably the most ergonomic rifle ever conceived, the AR15, to nearly every caliber ever conceived. Something CMMG is extremely well known for today.
To fully understand the big deal behind the MK47, we have to remember what it was like 5 years ago. Several companies tried to adapt the AR platform to the 7.62×39 round with limited success. Problems would usually arise in these other rifles due to 2 main issues. The first one being getting the rifle to reliably function. The AR pattern magazines that fed the 7.62×39 round back then were somewhat lacking and caused a ton of malfunctions. The massive second issue was if you could get the rifle to feed for awhile, the thin AR-15 556 bolt face that was bored out to accept the much larger round would crack, leaving a somewhat displeased owner.

Well, CMMG dropped what at the time may have been the biggest thing to hit the AR-15 world to that point, the MK47 Mutant. This crazy looking rifle addressed these issues and more. It completely eliminated the AR-15 pattern 762×39 magazines and replaced them with the extremely proven and extensively tested and reliable AK-47 magazines. They addressed the bolt issue by using what is essentially an AR-10 sized bolt, meaning that the walls of the bolt face are still very thick when they’re machined out to hold the larger round. Not only that, but they actually came up with their own receiver size. AR-10s can be a little big and bulky, so they made this AR-10 sized bolt function in a mid-size receiver set that is slightly larger than an AR15, but significantly smaller than an AR10. That is what makes up a mutant, a combination of an Ak-47, an Ar-15, and an AR-10; and for those who have had the opportunity to shoot one, it’s a thing of beauty.

The Mutant is a pleasure to shoot; the mid-size receiver absorbs the recoil well, making it a very pleasant shooter. It is also very accurate, and we were easily able to get hits on targets out to 300 yards. I like the Mutant because it kind of spreads that gap between the AR-15 and the AK-47. If you’re an AR-15 guy looking to experiment with an AK-47 and the 7.62×39 round, the MK47 is a great starting point. The same could be said for an AK-47 guy looking to get started in the AR-15 world.
