Mesh for site protector
 

Hey ASC, I am in need of materials for protecting my 40mm (it's big, I know) red dot site from bb impact. I already have a flip up plastic/rubber frame for it but I need to know what type of material to use inside the frame, I was thinking mesh but I don't know what type to get or where to buy it. I've tried 1/2 inch plexiglass but it didn't like any of the adhesives I own (always ended up fogging the lense, even when I used CA glue). Any ideas?

They can be expensive, but they definitely work.

I purchased a Leupold ARD (old, cheap version) for my scope with a Butler Creek flip-up lens cover.

Otherwise, stamped steel mesh or just regular metal mesh will work as long as you cover the sharp edges.

I've heard of some people building killflashes using straws.

Yeah, already have the kill flash frame (flip up), just need the material for inside it. any idea on what kind of store would carry such a mesh or stamped metal?
