Holosun 503 Killflash – 0.4mm nozzle version

This design is confirmed to fit the Holosun 503G/503xxx series of red dots. If you have a 403 series of holosun, i designed this model for them: https://makerworld.com/en/models/1048009#profileId-1034233This is a killflash/ARD (anti-reflective device) cover for the holosun 503G. It will most likely work on the other holosun 503 series red dots, but i don't currently have any to test with. If you have one of these and it doesn't fit, let me know the dimensions and I can make the necessary changes. Works very well as both a cover and a ARD, while still allowing easy viewing of the red dot. It is just a friction fit, but once it is on, it is on there pretty snug.
