Reflex sight lens material
 

I have had a reflex sight for almost a year before the lens got shot out. I have tried replacing the glass(?) with every possible material imaginable and cant get the reticle to show up. Does anyone know what material I can use to replace the one that shattered or an alternative solution?

The sight is similar to the one in the picture below.

They have a special coating, I don't think you'll be able to replace it easily.

They cost effin cheap, honestly just get a new one. You're better working 3 or 4 hours to pay it than waste 10 trying to replace the lens :) You can always buy one of these rail-mounted plexiglass shields and mount it right in front so the new one doesn't get shoud out too.
