I have a Moss 500 Mariner with a Truglo electronic reflex sight; the rectal can be either red or green in dot, cross hair, or bulls eye. I really like the sight, very quick to aim and accurate but I am concerned about the fragility of it and the fact that it needs batteries. I always have it off and it seems like the batt life is pretty good though, still don't want to take a chance at it failing at the wrong time. I am wondering what other options may be good with that in mind, such as ghost ring sights with tritium front sight or save and upgrade to something like an Eotech. I would prefer something that I can mount on a picitany (sp) rail and works well with a Knoxx stock- I know I have a tacticool shotgun . It's important though that the sight works well both in the daytime and low light conditions.
