CMMG DISSENT Upper Group - Armor Black, MK4, 5.56mm, 16.1"
The CMMG DISSENT Upper Group is the ultimate upgrade or starting point for any bufferless AR build. Chambered in 5.56x45mm with a 16.1" barrel and finished in a durable Armor Black Cerakote, this upper group is built on the patent-pending Compact Action Direct Impingement system that houses the entire action and recoil assembly within the upper receiver. The result is a more compact and streamlined platform compared to traditional AR pistols, without sacrificing reliability or performance. Compatible with any mil-spec lower receiver, and bundled with a 1913 Picatinny rail end plate, this upper group gives you the flexibility to run a folding stock for a compact carbine or add accessories for a pistol build. The forward non-reciprocating left-side charging handle enables quick bolt operation without breaking your sight picture.
