CMMG Dissent MK4 .300 AAC Blackout Features

This rifle features the CMMG ZEROED SVD Brake, which is pinned and welded to meet overall length requirements, enhancing recoil reduction and control. The adjustable gas block allows for custom tuning of the rifle’s cycling, tailored to different ammunition types or suppressor use. Its direct impingement operating system is streamlined with a unique Dissent side charging handle, providing a non-traditional yet user-friendly charging option that can be reversed for left or right-handed users.

The CMMG Dissent MK4 is equipped with a proprietary 13.5-inch handguard that supports a variety of attachments for customization. The upper and lower receivers are made from 7075 T6 aluminum, ensuring a robust framework without compromising weight. The rifle is finished with a durable Cerakote coating that not only protects it from the elements but also gives it a sleek, modern appearance.
