Daniel Defense - RIS III 9.5" M-LOK Rail Interface System Black

SOCOM-Proven Design with Modern M-LOK Versatility.

The Daniel Defense RIS III Rail Interface System builds on the legendary two-piece RIS II rail platform that has been trusted by U.S. Special Operations Command (SOCOM) since 2006. The RIS III maintains the same proven free-float barrel design, uninterrupted upper rail, and rugged construction—while reducing weight and adding modern M-LOK modularity.

Machined from aircraft-grade 6061-T6 aluminum, the RIS III 9.5" handguard features seven M-LOK attachment positions along the handguard and integral QD sling swivel attachment points on both sides. The result is a compact, duty-grade rail system ideal for modern AR builds where strength, accuracy, and accessory flexibility matter.
