Daniel Defense has just unveiled their new DDM4 Rail which uses their patented Bolt-Up System, developed originally for the USSOCOM RIS II. Instead of 6 bolts, the DDM4 Rail only requires 4 bolts and lower rail in this model is closer to the barrel.
Interestingly, the new DDM4 Rail will only be available as part of an upper or full rifle configuration. Additionally, DDM4 versions traditionally offered with an Omega X or Omega X with FSP will be replaced with the DDM4 Rail. However, two of the Daniel Defense models will remain unchanged. The DDM4v7 series will continue to be built utilizing the Daniel Defense Modular Float Rail 12.0. Production of the Daniel Defense MK18 will will continue to include the RIS II designed for USSOCOM.
In a press release, Jordan Hunter, Marketing Manager at Daniel Defense related, “This one--piece design has a more narrow profile which lends itself to better weapon manipulation. Front and Rear Sling Adaptors are integrated into both the left and right side rails. The DDM4 Rail measures 1.9” wide, 2.165” high with an inner diameter of 1.08”.
