CMMG Dissent MK4 Features

This rifle features a robust direct impingement system and an adjustable gas block, allowing for custom tailoring of the gas flow to optimize performance and reduce recoil. The mid-length gas system, combined with the unique CMMG ZEROED SVD muzzle brake, significantly mitigates recoil and muzzle rise, enhancing the shooter’s control and accuracy on follow-up shots. The innovative Dissent side charging handle can be configured for either left or right-handed shooters, adding to its operational versatility.
