## Description

The CMMG Dissent is chambered in .300 Blackout and built around a 16.1-inch barrel with a 1:7 twist. The .300 Blackout caliber lets shooters switch between supersonic and subsonic loads without adjusting the platform, which makes it practical for suppressed use. The Magpul SGA stock and standard grip handle the weight of 7.8 lbs without issues during normal range sessions.

### Detailed Features

The Dissent runs a Zeroed Drop-In Single Stage trigger with a short, crisp pull that holds up well for follow-up shots. The Cross-Bolt safety sits in a familiar position and doesn't slow down access. CMMG's radial delayed blowback operating system manages .300 Blackout's sharper impulse better than a straight blowback design would, and it cycles reliably across both supersonic and subsonic loads.

The 16.1-inch barrel keeps the overall length at 38.1 inches, which is maneuverable enough for indoor use while retaining ballistic performance beyond what a short-barreled version would give. The Magpul SGA stock has a solid lockup and a cheekweld that works for both optics and iron sights.

## What Customers Say

*AI-generated insights from customer reviews*

The CMMG Dissent .300 Blackout gets generally positive marks for its compact handling, .300 Blackout versatility, and build quality. The ability to run subsonic loads quietly, especially with a suppressor, is the most frequently cited selling point, and the radial delayed blowback system draws praise for its reliability with both load types.

Recurring criticisms center on three things: the 10-round magazine capacity feels limiting to shooters used to 30-round AR mags; the rifle runs heavier than expected when loaded up with optics and a light; and some users report a break-in period before it cycles consistently with lighter subsonic rounds. Accessory availability is narrower than for standard AR-15 platforms, which matters to anyone planning heavy customization.

Price is the usual dividing line. Buyers who prioritize the .300 BLK suppressor-host role tend to think it's worth the cost, while those looking for a general-purpose rifle find cheaper alternatives that check most of the same boxes.
