OK I understand how they work but my main question is I know my fancy reaction sights would be toast. But would they Metropolite or Trijicon reaction sight with tritium in the scopes still be fine (I dont want to take one apart to find out)? Or is there a circuit board in them also? I guess I wans't as clear as I thought. My wife says that allot. Sights light the Meprolight Self-Powered Day/Night Reflex Sight And trijjicons Relex sight also.
