Daniel Defense Rail Interface System III, RIS III, 9.5", Black (01-004-02976-006)

New for 2023

The Daniel Defense RIS III Rail Interface System takes the battle-tested 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 rails of the RIS II. But you also get seven M-LOK attachment points along the handguard, plus integral QD swivel attachment points on both sides. The result is a rock-solid rail based on what the pros use that accommodates accessories using the popular M-LOK attachment system.

  • Two-Piece Design for USSOCOM Allows for Attachment of M203 and M320 Grenade Launchers when Lower Rail Section is Removed (RIS III 12.5 & 13.0 FSP Only)
  • Aircraft Grade 6061-T6 Aluminum Construction
  • Battle-Tested, 6-Bolt Bolt-Up System Securely Attaches Handguard to the Upper Receiver
  • Grade 8 Military Specification Fasteners
  • Uninterrupted Upper Rail Platform
  • Integral QD Swivel Attachment Points with Limited Travel
  • Mil-Spec Type III Hard Coat Anodized Finish (FDE or Black)
  • Backward Compatible with RIS II Bolt-Up System—Utilizes Same Barrel Nut & Bolt-Up Plate
  • RIS III Upper Rail Is Fully Compatible with RIS II Lower Rail, Enabling M-LOK attachment on Upper and Picatinny Attachment on Lower
