I designed and 3d printed this protective cap that holds a 1/8 acrylic lens over the glass to prevent damage from airsoft or Sim rounds.
This is a friction fit item, the more times you put it on and remove it, the less secure it will be. That shouldn't worry you much unless you choose to remove it several times a week for a long time.
It is printed in PLA+ and should hold up fine to heat from the rifle. I have not tested it next to a suppressor, so if you do and there is an issue, lmk and I'll send you a new one.
Each cap will come with 2 lenses.
I only have a design to fit the Modlite phlv2 and okw Gen 2 head. The gen 1 head is bigger.
PM is best but email works.
