The Daniel Defense RIS III Rail Interface System takes the proven design of our two-piece RIS II rails—used by U.S. Special Operations Command (SOCOM) since 2006—and reduces weight while adding versatility by utilizing M-LOK attachment. You get the same proven free-float barrel design, durable aircraft-grade aluminum construction, and an uninterrupted upper rail platform with Mil-Spec 1913 rail of the RIS II. But you also get seven M-LOK attachment points along the handguard, plus integral QD swivel attachment points on both side.
