I was cleaning the glass (which I rarely do as I rarely shoot these days) on my ACOG 4x32 (TA01NSN).
 
I noticed spots on the objective lens, and saw they are actually on the inside.
 
Any idea on what this may be, and if it is normal?  I know some mfrs put gas inside, I did not think ACOG did but maybe that is a tritium deal ;-)  ?
 
Any info would be appreciated, thanks

Do you see the spots when looking through the scope?  if not, i wouldn't mess it.

Thanks for the reply, I do not see them when looking straight through it is nice and clear...you have to hold the objective at a certain angle to see the "spots" / gas / whatever it is

My ACOG had the same thing.  They were not noticeable to me at all though when looking through it from the eye piece.

Tritium is a gas and it will be in a glass capsule so it wont be that. You can call Trijicon and talk to them about it. http://www.trijicon.com/contact.cfm
