The Daniel Defense RIS III rail interface system is an evolution of the trusted RIS II design, renowned for its use by U. S. Special Operations Command (SOCOM) since 2006. This advanced rail system maintains the robust, free-float barrel design and the durable aircraft-grade aluminum construction that users have come to rely on. It features an uninterrupted upper rail platform with a mil-spec 1913 rail, ensuring compatibility and reliability in demanding conditions. What sets the RIS III apart is its enhanced versatility and reduced weight, achieved through the integration of M-LOK attachment technology. This modern update provides seven strategically placed M-LOK attachment points along the handguard, offering users unprecedented flexibility in bipoding accessories. Additionally, the system includes integral QD swivel attachment points on both sides, facilitating quick and secure sling attachment. The Daniel Defense RIS III is engineered for those who demand performance and adaptability in their equipment, making it an ideal choice for professionals and enthusiasts alike who seek a cutting-edge rail system that does not compromise on durability or functionality.Design of free-floating barrels to enhance accuracyThe M-LOK attachment system allows for mounting at seven distinct positions along the length of the handguard6061-T6 aluminum, aircraft-gradeThe 6-bolt bolt-up system effectively secures the handguard to the upper receiverMilitary specification grade 8 fastenersContinuous upper rail platform and military specification 1913 picatinny railCompatible with the RIS II bolt-up system - employs the same barrel nut and bolt-up plateThe RIS III upper rail is fully compatible with the RIS II lower rail
