818773023054 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. FEATURES: Free-Floating Barrel Design for Increased Accuracy M-LOK Attachment on 7 Surfaces Along Length of Handguard 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

Description:

Upgrade your AR-15 with the advanced RIS III Rail System from Daniel Defense.

The Daniel Defense RIS III Rail Interface System combines a battle-tested design with modern advancements to enhance your shooting experience. Originally designed for U.S. Special Operations Command (SOCOM) since 2006, this rail system reduces weight while increasing versatility through M-LOK attachment options.

Key Features:

  • Free-Floating Barrel Design: Increases accuracy by allowing the barrel to float independently.
  • M-LOK Attachment: Seven attachment points along the length of the handguard for optimal accessory placement.
  • Two-Piece Design: Specifically designed for USSOCOM, allows for the attachment of M203 and M320 grenade launchers when the lower rail section is removed (RIS III 12.5 & 13.0 FSP only).
  • Durable Construction: Made from aircraft-grade 6061-T6 aluminum for superior strength.
  • Secure Attachment: Features a battle-tested, 6-bolt bolt-up system that securely attaches the handguard to the upper receiver.
  • Grade 8 Fasteners: Military specification fasteners ensure maximum reliability.
  • Uninterrupted Upper Rail Platform: Provides a seamless surface for mounting optics and accessories.
  • Integral QD Swivel Attachment Points: Limited travel for enhanced stability.
  • Mil-Spec Finish: Type III hard coat anodized finish available in FDE or Black.
  • Backward Compatibility: Compatible with the RIS II bolt-up system, utilizing the same barrel nut and bolt-up plate.
  • Full Compatibility: RIS III upper rail is fully compatible with RIS II lower rail, allowing M-LOK attachment on the upper and Picatinny attachment on the lower.

Enhance your firearm with the Daniel Defense AR-15 RIS III Rail and experience the difference that quality engineering makes in the field.
