M4A1 FSP Rail Interface System (RIS) II

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 M4A1 FSP feature a cut-out in the top rail to accommodate a standard front sight base on a carbine-length gas system.

Cannot go wrong!
Amazing rail. Strong , durable, and light compared to others. Used it whilst in the military , and now use it as a Civ shooter cannot go wrong with it. The extra real estate is was always a plus when using lights and lasers. I personally like the feel of the cheesegrater and have no reason to go to KeyMod or MLOK. People will often discuss the weight difference , well comparatively speaking I would sacrafice some weight , for the extra real Estate, modularity, and strength of the system. I have never had a bolt walk on me , and can say it is the most durable rail I have personally used in a work capacity or a plinking capacity.
