M4A1 Handguard Rail Cover missing (one side)

The M4A1 is supposed to have both rail covers on just like the DRS-IAR, as seen in the picture below the rail covers aren't on both sides of the weapon, also the rail covers are supposed to be used with the weapon handling with the left hand using a c-clamp to hold the handguard rail cover.

A few of these weapons only have the rail covers on one side, however this would not be considered a finished content or product. This can be fixed by making the one side disappear when a flashlight is applied or a laser is applied.
