Detailed Features 

 
The 16.1" barrel with a 1:7" twist is matched to the .22 ARC cartridge, which runs well at distances useful for both target work and small game. The Zeroed Drop-In Single Stage trigger gives a consistent pull with no take-up adjustment needed out of the box. The cross-bolt safety is straightforward and accessible without changing your grip. 
 
At 8 lbs. and 38.1" overall, the Dissent is on the heavier side for a .22 ARC platform, though that weight contributes to stability during extended shooting sessions. 
 

Target Audience 

Sport shooters and hunters who want the .22 ARC cartridge in a semi-automatic platform. Works for competitive shooting where the caliber is permitted, and for small game hunting where a reliable semi-auto is preferred. 
 

Usage Scenarios 

• Target shooting at various distances where the .22 ARC's flat trajectory is an advantage 
• Small game hunting where 10-round capacity and semi-auto cycling matter 
• Competitive events where the caliber and platform combination is allowed

Discussion around the CMMG Dissent in .22 ARC is generally positive, with some practical criticisms.

The rifle's design and build quality come up favorably, particularly from shooters familiar with CMMG's construction standards. The semi-auto action is described as reliable and easy to run, and accuracy reports at various distances are consistently solid. The Zeroed Drop-In trigger is appreciated for its clean break and consistency without needing adjustment out of the box.

The .22 ARC cartridge draws attention as a versatile option, flat enough for target work, capable enough for small game hunting. Users tend to see the caliber as a meaningful reason to choose this platform over a standard .22 LR semi-auto.

Criticisms center on a few recurring points. The 10-round magazine capacity is seen as limiting compared to other rifles in this class. The price is a common discussion topic. Some buyers feel it's higher than expected for a .22 caliber platform, even accounting for the ARC cartridge's performance step up. Aftermarket accessory availability is mentioned as a concern for buyers who want to customize heavily.

At 8 lbs. the Dissent is not the lightest option in this category, which comes up in field carry discussions. Overall the rifle is seen as a capable and reliable platform for its intended uses, with the main hesitation being price relative to similar semi-auto options.
