MK18 Rail Interface System II, RIS II

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

The Daniel Defense MK18 RIS II is designed to work specifically on the MK18 CQBR! 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 RIS II MK18 is NOT compatible with an M203.

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. The Daniel Defense RIS II is an innovative upgrade to the M4 platform and is available for commercial purchase directly from Daniel Defense or any authorized distributor.

RIS II - Perfection
I have had four of these rails and they are built rock solid. The install is straight forward. The bottom rail detaches allowing you to clear debris such as rocks, grass, sticks, sand, blood, from the barrel. The FDE color matches all terrains and environments and compliments Magpul's FDE color. This is what the US Special Forces use, its good enough for them, then its good enough for you.
