The RIS III Rail Interface System by Daniel Defense has been designed to incorporate the battle-proven design of their two-piece RIS II rails, which have been in use by U.S. Special Operations Command (SOCOM) since 2006.

It features an uninterrupted upper rail platform with Mil-Spec 1913 rails as well as a free-float barrel design, durable aircraft-grade aluminum construction, and 7 M-LOK attachment points along the handguard.
