I have a 1 MOA dot Eotech that came used on a rifle I bought while ago. The Eotech was brand new though and seller gave me the box it came in etc.
For past year even if I cranked it up, the 1 MOA dot would scatter a bit but still a very precise dot- I actually liked it for long range accuracy without the circle around it (I couldn't choose the reticle cause came w rifle).
Put a new Surefire CR123 battery in it few mos and stuck in safe and haven't shot it or tested it since.
Took it out tonight just to play with and unless I have it on a very low setting, there is a red halo effect around the dot and also when crank it up a faint red line going across lower half of the reticle.
Like said, the dot is still perfect 1 MOA but I have to have it on a setting that is just right and before if I cranked it up even to full power that tiny dot would scatter a bit but still very precise- just extremely bright but zero halo effect w red faint circle and faint red line.
Is this normal since I put a new battery in it and just need to make sure I don't give it too much juice or did something happen to it somehow while sitting in my safe!!?? Just seems strange because even though I don't use AR for home defense, before if I ever needed it in a pinch I felt I could just push the on button a bunch of times and be gtg- that's not the case anymore and this red halo shows up and red line that never did before even on brightest setting.
