Daniel Defense Rail Interface System III, RIS III 13″ FSP (FDE)

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.

Note: M203 hangers will interfere with pinned & welded muzzle devices.  Daniel Defense suggests contacting a qualified gunsmith for RIII rail installation on any firearm or URG with a pinned & welded muzzle device.
