The CMMG Mk47 Mutant is designed to accept standard AK-47 magazines, including drum magazines. This offers enhanced reliability for the 7.62x39mm cartridge compared to proprietary AR-style magazines.

What are the accuracy expectations for the CMMG Mk47 Mutant?

The CMMG Mk47 Mutant is reported to offer AR-15 level accuracy. With premium ammunition, it can achieve sub-MOA groups, and with steel-cased ammunition like Wolf or Tula, expect groups around 1.5 inches.

What gas system does the CMMG Mk47 Mutant use and why?
