Long story short I noticed that there's a small circle rubber seal type of thing on the bottom of my holosun 515t , red reticle. Mine is partially ripped, I only took it off the stock mount cause the qd broke. I have a spare mount by adm so imma use that.
Does anyone know what that seal is for? I'm assuming purging or putting nitrogen or whatever gas they use into the optic. But idk.
I called holosun and tgey told me write an email. Did that 2 weeks ago. Wrote another email last Tuesday and friday. Still no reply so I called yesterday (monday) and the guy told me to write an email again. So I did. Kinda irritating they keep telling me to write an email and still no response.
