DD DD4 MK18 RIII SBR 556 10.3″ 32RD

LESS WEIGHT, MORE FLEXIBILITY-with additional features that make this unmatched short-barreled rifle even lighter, more maneuverable, and more controllable. The MK18 RIII features a fully ambidextrous lower receiver, and Daniel Defense replaced the RIS II rail system with a lighter-weight RIS III rail system that utilizes M-LOK attachment instead of picatinny. Class III dealers only, all NFA rules apply.
