CMMG DISSENT MK4 .300 BLK 16.1″ Barrel

The CMMG DISSENT MK4 in .300 BLK pairs a 16.1-inch chambered barrel with the DISSENT folding stock platform for a compact, adaptable AR-style rifle. It ships with an adjustable gas block to tune supersonic or subsonic loads and includes two Magpul 30-round PMAGs. For an optic that complements the DISSENT MK4 without exceeding $1,000, consider a Vortex Strike Eagle 1-6×24 for close-to-mid-range versatility.
