Product Description
The Daniel Defense RIS III Rail Interface System modernizes the proven two-piece RIS II design by reducing weight and adding versatile M-LOK mounting along the handguard. Built from aircraft-grade 6061-T6 aluminum, the RIS III maintains a rigid free-float barrel design for accuracy and features an uninterrupted, Mil-Spec 1913 Picatinny top rail for consistent accessory alignment. This 13-inch Flat Dark Earth (FDE) rail assembly uses Daniel Defense’s secure 6-bolt Bolt-Up system and includes integral quick-detach (QD) sling swivel attachment points. The rail is also designed around a front sight post (FSP) cutout and is backward compatible with the RIS II Bolt-Up system.
Product Highlights
- Free-float rail design helps maximize accuracy by reducing barrel contact and external pressure.
