Description
Product Overview
The CMMG DISSENT Mk4 compact-action 5.56mm NATO upper assembly is built for an ultra-compact AR-style setup using a direct-impingement system with a unique compact action that eliminates the need for a traditional buffer system. The result is a shorter overall build length while keeping standard AR-style lower compatibility and familiar ergonomics. This configuration features a 10.5-inch 4140 chrome moly nitride barrel, a 9.6-inch M-LOK handguard, and an optics-ready Picatinny rail for straightforward mounting options.
Key Features
- 10.5-inch 4140 chrome moly barrel with salt bath nitride finish for improved durability
- 7075-T6 aluminum upper receiver for strong, lightweight construction
- Direct impingement compact-action design reduces the need for a buffer system in typical AR layouts
- Proprietary 9.6-inch M-LOK handguard with pistol-length gas system
- Adjustable .750 inches gas block for tuning and reliability
- Non-reciprocating left-side charging handle for ambidextrous-friendly operation when paired with the right controls on your build plan (NFA rules apply where applicable to the full firearm setup)
Add this DISSENT Mk4 upper to a compatible Mk4 or mil-spec AR-15 lower receiver to build a compact 5.56mm NATO setup with modern mounting options and a short, efficient profile.
