MARKSMAN AR / M4 Steel Dust Cover

AR-15 / M4 steel dust cover set, laser engraved on both sides of the caliber mark.

Suitable for :

• Genuine specification M4 type GBB airsoft.
• GHK M4 GBB airsoft.
• VFC M4 type GBB can be installed, but requires the use of the original pin.

MARUI MWS M4 GBB can be installed, but the original pin is required and cannot be capped.

If there is a tolerance in the hole of the pin, it can be replaced by the original pin on the original gun.

The tolerance of each brand may be slightly different, so it may not be possible to put the cap on smoothly, and it should be slightly resharpened according to the situation.
