Re: pros/cons eotech on coyote rig?
If you have Flip up iron sights installed along with the Eo-Tech, if the batteries die, you are still good to go. I have an EO-Tech on my 6.5 Grendel, and its spot on out to 300 yards. Put NV behind it and its a great setup for night hunting. My M4 has an EO-Teck 3-2 and a 4X magnifier. I just installed it over Christmas, but it should be good to 500 since it has a ballistic reticle.
Night vision pretty much mandated using an Eo-Tech. That being said, I am still pretty happy with them.
