An integral PDW design for the FDMA DD17.2 platform. Includes top and rear picatinny mounts for optics and a brace. Assembly is identical to the FDMADD17.2, but will need a second mag release with a trimmed mag release spring. Front charging handle requires removal of front sight and requires a M3x5 screw and nut to embed into the handle. The brace requires a standard M5x30 hex cap screw, and the brace swivel uses a 1/4" pin or bolt.
