Compact, folding, and mission-adaptable rifles are increasingly popular for operators and serious shooters who need full-size performance in a smaller footprint. Modern bufferless designs remove the traditional receiver tube constraint, opening up options for folding stocks, braces, and improved ergonomics without compromising reliability.

CMMG DISSENT MK4 is built around CMMG’s patented Compact Action system and a bufferless receiver engineered for use with folding stocks and braces. Chambered in 6mm ARC and finished in Sniper Grey cerakote, the DISSENT MK4 uses direct impingement operation without a buffer tube assembly, delivering the familiar AR-style timing in a more compact package. One 10-round magazine is included. Shop this product

Design and operating system

The DISSENT MK4’s Compact Action system keeps the bolt and carrier timing optimized for direct impingement while eliminating the buffer tube. That allows a folding stock or stabilizing brace to be used without modification to the operating system. The side charging handle mounted forward of the action is non-reciprocating and reversible for left- or right-handed users, making chambering and malfunction clearance faster from modern shooting stances.

Controls and ergonomics

Controls are placed for intuitive access in high-stress situations. The side charge’s forward placement keeps hands clear of optics and rail-mounted accessories. The bufferless layout shortens overall length when folded, making transport and storage easier while preserving a familiar trigger and bolt feel.

6mm ARC: capability and applications

Chambered in 6mm ARC, the DISSENT MK4 delivers a flat trajectory and efficient long-range performance from a modest platform. The caliber is well suited for precision work, medium-game hunting where legal, and roles demanding extended effective range with manageable recoil. For shooters wanting a compact semi auto in a high-performance intermediate cartridge, this configuration balances terminal performance and controllability.
