My EOTech doesn’t have the night vision settings, and it runs on AAs instead of C123s. I can’t remember it’s product number.
Travis, you probably have the EOTech Mdl 512...I have the same one...great HWS. Note to Blood of Tyrants: In addition to the EOTech the C-More sights are also quite good and cost less than the EOTechs.
One thing to keep in mind however with regards to Red Dot or Holo sites is how old your eyes are. I’ve found that if your hauling middle-aged eyes around in your head and things are a bit blurry these days, regardless of whether you whether contact lens or glasses you may still have some bluriness on the red dot or the HWS reticles.
You might want to find a friend (or go to an indoor range where you can rent AR’s, etc), and try the different sights out before you spend a lot of money on one.
I’m an FFL and have mounted a number of optics. My advise is to try a bunch out before investing and see which one works best given your particular eyesight, shooting platform and shooting needs).
That is what I have on my M-4gery.
