About M4A1 RIS II:
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 accomdate a standard front sight base on a carbine length gas system.

About Daniel Defense: (link)
Daniel Defense engineers and manufactures parts and accessories for Military Small Arms. We are intensely focused on providing top quality small arms product solutions to our Military and Law Enforcement community with innovative engineering and our state of the art manufacturing facility.
Daniel Defense was founded in 2000 by Marty Daniel.
Mr. Daniel began Daniel Defense to provide readily-available, quality small arms products in the commercial market.
After a few years of concerted effort to providing premium quality and the best value small arms parts to the commercial market, Mr. Daniel's M4 Rail™ was adopted by the United States Army Marksmanship Unit, for the Designated Marksman Rifle Program.
Once this contract was won and Daniel Defense began delivering against it, Mr. Daniel and his team took a crack at the coveted United States Special Operations Command SOPMOD contract. Daniel Defense was recently awarded the sole source contract to produce the RIS II for the SOPMOD block II. With all of Daniel Defense's military business, Daniel Defense still has Mr. Daniel's initial vision of providing top quality products at an awesome value to the commercial market at the core of our company's values.
