You can't hit what you can't see.
Direct sunlight degrades the sight lenses. Sand and dust scratch and scour the lenses. Pretty soon, the RWS is as blindas a bar.
So whenever the sights aren't in use, keep 'em covered. The day sight uses a small lens cap and the night sight takes a large lens cap.
When the sights are being used, screw the caps into their storage locations. That'll ensure the caps are available the next time they're needed. The day sight cap screws onto the sight servo housing. The night sight cap attaches to the ammo box.
You may need to periodically clean the threads on the caps and their storage locations to help prevent cross-threading. A good scrubbing with a toothbrush or something similar will make quick work of dirt and sand.
