CMMG Mk4 Dissent Rifle 5.56mm, 14.5 in Pinned Barrel, Black

About this product

The CMMG Mk4 Dissent is a compact, purpose-built 5.56mm rifle intended for versatile range and duty-style applications. It ships with a 14.5-inch barrel and a CMMG ZEROED SVD Brake that is pinned and welded to the muzzle assembly, extending the barrel assembly to a 16.1-inch overall length. The rifle is configured with a 13.5-inch M-LOK handguard, an adjustable gas block and a DISSENT side folding stock that provides an adjustable length of pull and cheek riser for user preference.

Controls and ergonomics favor modularity and practical use: a forward non-reciprocating charging handle and top Picatinny rail on the handguard allow straightforward accessory mounting and manipulation. The adjustable gas block gives the operator the ability to tune the gas system for different loads or suppressed use.
