Frequently Asked Questions

What makes the CMMG Dissent a unique AR platform?

The CMMG Dissent is a buffer-less AR variant that uses a truncated bolt carrier group with dual recoil springs. This design allows for the integration of folding stocks, making it particularly advantageous for Personal Defense Weapon (PDW) roles.

How does the CMMG Dissent handle different calibers?

The Dissent platform is multi-caliber, supporting rounds from 9mm to .308 Win. Rifle calibers operate on a Direct Impingement (DI) system, while pistol calibers utilize CMMG's proprietary Radial Delayed Blowback (RDB) system for reliable cycling.

What are the main criticisms of the CMMG Dissent?

Criticisms include the ergonomics of the charging handle and accessory placement due to the taller upper receiver. The included B&T stock is noted as potentially overpriced and uncomfortable, and some proprietary lower parts may have usability issues.

Is the CMMG Dissent suitable for left-handed shooters?

For left-handed shooters, the 9mm Dissent configuration can be problematic, especially when suppressed, as it may eject significant gas and debris into the shooter's face. This is a notable ergonomic consideration.
