Daniel Defense MK18 Rail Interface System II (RIS II) Handguard - 10 Inch, Flat Dark Earth


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 important, 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.

Best Rail Made

Posted by Conrad | (Posted on 12/12/2020)

Not much to say, everybody knows what this rail is. It is still one of the strongest rails made and the best looking rail on the market. There is plenty of space to mount lights and still get a good grip on the rail. There is a reason they are always sold out.
