The Daniel Defense MK18 RIII has less weight, more flexibility, and 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.
