Anybody have any experience with these? I picked one up a while back and it just seem that the tritium doesn't glow as bright as it should. It is only visible in total darkness, so basically If I can see through the scope, I cannot see the tritium glow. I know these are night vision compatible, which leads me to believe that it is supposed to be this dim. It was made in 2008 and it still under warranty, and I have a RMA from trijicon to ship it back, but I would rather not ship it back and spend the money on shipping plus be without it for a couple months if there is nothing wrong with it.
