Daniel Defense Mk18 RIS-II Rail, Black with hardware
Daniel Defense is the Sole Source Provider of the RIS II to the United States Special Operations Command (SOCOM) 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 Grenade Launcher
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.
Note: Charlie's is bringing you a new Daniel Defense rail, not used. Charlie's is a Daniel Defense dealer, and we buy new rails, new old stock, and also take-off rails during our builds.
Most of the Mk18 rails are "new take-off," meaning that your rail came off a Mk18 rifle or new upper assembly, and was carefully removed to not scratch the rail or the hardware. Some hardware items, like screw and bolt heads might show minor signs of use during removal. Charlie's inspects each item, and if the screw or other hardware has been significantly worn or damaged, the part is replaced.
