Duration: 12:18

The CMMG Dissent is a compact PDW built on an AR platform, featuring a bufferless design with dual recoil springs in the upper receiver. While available in .300 Blackout, 5.56, and 5.7x28mm, the 6.5-inch barrel length makes .300 Blackout or 5.7x28mm the recommended calibers for better terminal performance. Its design prioritizes a 'bag gun' philosophy, fitting discreetly into a backpack, though the stock brace can be a point of failure.

Frequently Asked Questions

What makes the CMMG Dissent a PDW?

The CMMG Dissent is classified as a Personal Defense Weapon (PDW) due to its ultra-compact size, designed to be easily concealed within a backpack. It features a bufferless AR platform with a short 6.5-inch barrel, making it highly portable.

What calibers are available for the CMMG Dissent?

The CMMG Dissent is offered in three calibers: .300 Blackout, 5.56x45mm, and 5.7x28mm. However, due to its short 6.5-inch barrel, .300 Blackout and 5.7x28mm are recommended for better terminal performance.

How does the CMMG Dissent's mechanism differ from a standard AR?

Unlike standard AR-15s that use a buffer tube, the CMMG Dissent features a bufferless system. It incorporates dual recoil springs within the upper receiver, similar to an AR-180 design, while maintaining a direct impingement gas system.

What are the potential issues with the CMMG Dissent's brace?

The SB Tactical FS1913 folding brace used on the Dissent can be a point of concern. It lacks a positive locking mechanism and has been observed to collapse under the recoil of more powerful cartridges like .300 Blackout, prompting recommendations for alternative braces.
