Product Information

Designed at the request of SOCOM to provide M203 compatibility while still providing a free float rail system. The Daniel Defense RIS II met this requirement without the need for special tools. The RIS II provides a rock-solid mounting surface via the patent pending bolt up system which allows for an uninterrupted top rail and simplified alignment to the upper receiver. The RIS II is available in Black and Flat Dark Earth. The FSP version has a cutout on the top rail to accommodate the front sight base on a carbine length gas system.
