But, unlike the other rail systems offered by Daniel Defense, the DDM4 Rail will only be offered as part of a complete rifle or upper receiver group and will not be available for individual sale.
Daniel Defense tells us that the new rail will replace the Omega X rail systems on all their factory-built offerings that are currently sold with the an Omega X or Omega X FSP handguard. Two of the Daniel Defense versions 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 rail designed for US SOCOM, the RIS II.
