CMMG Mk47 Meltdown!

Published on April 17, 2018
Duration: 16:11

The CMMG Mk47 Mutant underwent a rigorous 'meltdown' test, firing 1,255 rounds of 7.62x39mm before its gas tube failed. This direct impingement rifle outperformed other DI rifles and even a Vepr AK-47 in sustained fire endurance. Magazine feed lips also failed under extreme heat, but the rifle itself remained functional until the gas tube gave out.

Quick Summary

The CMMG Mk47 Mutant fired 1,255 rounds of 7.62x39mm in a stress test before its direct impingement gas tube failed, reducing it to single-shot. This endurance surpassed other DI rifles and a Vepr AK-47, with magazine feed lips also failing under extreme heat.
