The CMMG Dissent MK4: Modern AR Engineering at Its Finest

The Dissent MK4 represents what the modern AR-15 platform should be. Chambered in 5.56 NATO with a 16.1" barrel, this rifle delivers the accuracy and reliability you expect from quality engineering, wrapped in a package that handles like a dream.

Key Features

Ergonomic Design

  • Side-charging handle keeps your shooting hand on the grip and eyes downrange
  • Non-reciprocating design means no distracting movement during operation
  • Ambidextrous 60/90-degree safety selector accommodates both left and right-handed shooters

Adjustable Stock System

  • Dissent side-folding stock for compact storage and transport
  • Adjustable length of pull to fit your frame perfectly
  • Integrated cheek riser for proper sight picture alignment

Accessory-Ready Platform

  • 15" M-Lok handguard provides multiple mounting points
  • Top Picatinny rail for optics and accessories
  • Muzzle brake included for reduced recoil

Gas System Flexibility

  • Adjustable gas block lets you fine-tune performance
  • Dial in the perfect setting for suppressed or unsuppressed shooting
  • Match your ammunition preferences without guesswork

Why the Dissent Stands Out

This isn't just another AR. The Dissent's thoughtful engineering—from the side-charging handle to the adjustable gas block—shows CMMG understands what modern shooters need. Whether you're at the range, in competition, or training for duty, the Dissent delivers smooth, reliable performance.
