Daniel Defense is the Sole Source Provider of the RIS II to the United States Special Operations Command!

The Daniel Defense Rail Interface System (RIS II) was designed at the request of the United States Special Operations Command (SOCOM) for the SOPMOD II program. SOCOM had a specific requirement for a free float M203 solution and Daniel Defense responded, designing a revolutionary product to meet the government's need.

The Daniel Defense RIS II allows the individual operator to free float the M203 grenade launcher without additional parts. As importantly, special tools are not required to mount the M203 grenade launcher. This was accomplished by integrating all of the needed parts to free float the M203 into the rail itself.

The Daniel Defense RIS II is to be used in conjunction with the MK12 Low Profile Gas Block.

The Daniel Defense RIS II free-floating Picatinny rail systems are designed to allow individual operator to quickly, and without special tools, mount M203 Grenade Launcher and precisely mount SOPMOD accessories to host weapon without effecting point of impact.

    DD RIS II m4 rail

    Posted by anonymous on Aug 23rd 2012

    Sick rail fit, finish and everything else about this rail is bad ass. I love mine and plan on using a mk18 ris II on a sbr. Really like this rail and it looks good on my bcm 14.5 build. I like the 12.25" length of this system also.
