CMMG made waves earlier this year with one of the most unique guns to hit the market in a spell.
The Missouri manufacturer’s Mk47 Mutant line offered shooters an AR that reliably fed off the all-pervading 7.62x39mm round. The project must have struck a cord, given it hasn’t taken long for CMMG to expand on the concept.
Recently, the company enlarged the Mutant line with the introduction of more compact models. In addition to its three original models, CMMG is now also offering the Mk47 Mutant as an AR pistol and short-barreled rifle. The company has also released California-compliant versions of the original Mutant rifles.
CMMG’s Mk47 K Pistol and SBR are fairly similar in design, each one built around a 10-inch medium taper barrel. There is a distinct difference between the two firearms, however—the most obvious being the SBR is outfitted with a buttstock.
This feature makes the rifle 27.5 inches in overall length, an inch longer than the Mutant pistol. And, more importantly to potential buyers, it also places the firearm under National Firearms Act regulation, requiring registration, transfer records and payment of a special tax.
The California-compliant Mutants, on the other hand, have undergone much simpler tweaks. The guns are shipped with 10-round magazines and a bullet button, in accordance with Golden State laws.
The new additions utilize many of the same features as the earlier iterations of the Mk47. Chief among these is the firearm's unique carrier group, which is based off the AR-10’s and features a beefier bolt face. These tweaks have been the key, the company has said, to making the venerable Russian cartridge workable on the AR platform.
The new firearms also accept AK magazines and drums, like the older versions. All of them feature the company’s single-stage trigger, except the AKM2, which is outfitted with Geissele’s SSA two-stage trigger.
The price on CMMG’s Mk47 K Pistol is $1,499; the Mk47 K SBR is $1,629. The California-compliant models’ MSRPs are similar to the originals: The Mk47 Mutant T CA is $1,549, while the Mk47 Mutant AKM CA is $1,699, and the Mk47 Mutant AKM2 CA is $1,899.
