Description
Daniel Defense RIS III Features Based on the legacy of the SOCOM-adopted RIS II the RIS III introduces modern enhancements including M-LOK compatibility and improved ergonomics. The continuous 1913 Picatinny top rail supports full-length optics or iron sights while integrated sling swivel sockets provide flexible mounting options for QD-compatible slings. Constructed from aircraft-grade aluminum and finished with a durable Type III hardcoat anodized black finish this rail system is built to withstand hard use in field and duty environments.
