CMMG Dissent in 300 Blackout! Virtus Competitor?

Published on December 23, 2022
Duration: 24:11

The CMMG Dissent in 300 Blackout offers a unique bufferless design inspired by the AR-180 and Sig MCX systems. It features a compact direct impingement system, providing a mild recoil impulse comparable to piston systems. While reliable with standard 5.56 magazines for supersonic 300 BLK, subsonic rounds benefit from 300 BLK specific magazines. The firearm boasts ambidextrous controls, a TriggerTech trigger, and an adjustable gas block for suppressed fire.

Quick Summary

The CMMG Dissent in 300 Blackout features a unique bufferless direct impingement system, inspired by the AR-180 and Sig MCX. It offers a mild recoil impulse and accepts standard 5.56 magazines for supersonic 300 BLK, though 300 BLK specific mags are better for subsonic rounds.

Frequently Asked Questions

What makes the CMMG Dissent's operating system unique?

The CMMG Dissent features a bufferless operating system inspired by the AR-180 and Sig MCX/Virtus. It uses a compact direct impingement system with dual guide rods and recoil springs, eliminating the traditional buffer tube.

How does the CMMG Dissent compare to the Sig Rattler in terms of recoil?

The Dissent utilizes a direct impingement system, which the reviewer notes results in a milder recoil impulse compared to the Sig Rattler's short-stroke gas piston system.

What are the magazine recommendations for the CMMG Dissent in 300 Blackout?

For supersonic 300 Blackout rounds, standard 5.56 magazines function reliably. However, for subsonic 300 BLK, specific 300 BLK magazines are recommended due to differences in bullet geometry.

Does the CMMG Dissent have an adjustable gas system?

Yes, the CMMG Dissent is equipped with an adjustable gas block. This feature allows users to fine-tune the gas system, which is particularly beneficial for optimizing performance when using a suppressor.
