OVERWATCH DM4 20″ 6MM ARC

The Overwatch DM4 in 6mm ARC with a 20” barrel is a long-range problem solver. Built for precision shooters who want bolt-gun performance in a faster, more adaptable semi-auto platform, this rifle delivers flat trajectory, minimal recoil, and consistent impact past 800 yards.

The 1:7 twist barrel is optimized for high-BC bullets that stay supersonic deep into the target zone. The 19” ZeroLok ARCA handguard gives full-length support with zero flex—ideal for tripods, barricades, and prone work under load. Integrated ARCA rail, M-LOK slots, QD sling cups, and a red dot mount shelf (riser required) give you modularity without compromise.

The 2 lb trigger, vertical grip, and fully adjustable precision stock create a dialed-in shooting position for long glass or LPVO setups. Suppressor-ready and mission-tuned, this DM4 pushes the AR-15’s effective range well past traditional limits.

Overwatch DM4 in 6mm ARC: Precision where it counts. Performance where it matters.
