CMMG DISSENT Mk4 5.56 14.5 in Pinned & Welded | 2x 30rd

The CMMG DISSENT Mk4 is a bufferless AR-style pistol chambered in 5.56x45mm that pairs a compact 14.5 inch barrel (pinned and welded to 16.1 inches) with CMMG’s Compact Action for reduced overall length and simplified operation. It ships with two Magpul 30-round PMAGs and features a reversible side charger, adjustable gas block, and a 13.5 inch proprietary handguard for accessory mounting. This configuration is suited to range training and action shooting competition where a compact, carbine-like handling profile is desired. A versatile optic such as the Vortex Strike Eagle 1-6×24 provides a durable, sub-$1000 option that matches the DISSENT’s intended engagement envelope.
