Daniel Defense MK18 RIS II Free Float Handguard Quad Rail AR-15 Mid Length Aluminum
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 Daniel Defense RIS II is to be used in conjunction with the MK12 Low Profile Gas Block. Its free-floating Picatinny rail systems are designed to allow the individual operator to quickly, and without special tools, mount a 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.
