Catastrophe Happened CMMG MK47 Dissent

Published on November 30, 2023
Duration: 14:06

This expert review from Tactical Considerations details a critical failure with the CMMG MK47 Dissent rifle. After extensive range testing, the handguard rail repeatedly separated from the upper receiver due to a sheared insert pin, rendering the rifle unsafe. Despite positive initial impressions and features like AK magazine compatibility and an adjustable gas block, the recurring structural issue prevents a recommendation. The reviewer's high-volume testing and direct communication with the manufacturer highlight a significant reliability concern for this platform in 7.62x39mm.

Quick Summary

The CMMG MK47 Dissent in 7.62x39mm experienced critical structural failures where the handguard rail separated from the upper receiver due to a sheared insert pin. This issue recurred even after part replacement, leading the reviewer to conclude the design may not be robust enough for the caliber, preventing a recommendation despite positive initial impressions.
