Designated Marksman Rifle
MK1 MOD1 DMR
The RD MK1 MOD1 DMR is a 16” designated marksman rifle chambered in 5.56 NATO, purpose-built for precision engagements and sustained reliability in dynamic operational environments.
Engineered for shooters who demand accuracy without compromise, the DMR 556 is outfitted with RD’s KFM Taper Lock Flash Hider, the Battle Arms Development RACK® ambidextrous charging handle for seamless manipulation, and a Nickel Teflon-coated two-stage trigger for clean, consistent break and control under pressure.
At the heart of the system lies RD’s patented threaded gas tube and gas block assembly—designed to minimize recoil, eliminate gas leakage, and maintain optimal cycling across varying conditions. The result: improved target retention, faster follow-up shots, and superior shooter confidence in mission-critical moments.
Whether deployed in overwatch, urban interdiction, or high-risk tactical operations, the MK1 MOD1 DMR delivers precision you can trust—round after round, mission after mission.
