This Quad Rail handguard is designed for fitting the MK18, .223 rifles, which is applicable to field combat practically.

  1. Clever top/bottom two-piece design with integral spinal cords/alignment housing for great fit.
  2. Free-floating barrel design for increased accuracy.
  3. Great accomodating capability for the accessories Installed on the rails, and it allows the individual operator to handle freely.
  4. The interrupted picatinny top Rail Platform with the FSP cutouts provides ample space for optics or includes removable front triangle flip sight. NOTE: The bottom rail does not have a cutout, not fit for the front sight base with bayonet lug.
  5. Desert Tan color is a lighter tan color than typical FDE (Flat Dark Earth), while Coyote Tan color is darker than FDE. Coyote Tan color is not exactly the same from batch to batch, sometimes it is darker and may easily mistaken for black. We will update the picture when the color difference is large.
