Need opinions on AR-15 Optics. I currently have a Red Dot Scopes (RDS) on my AR. Haven’t shot it in a while and when I took it out I checked to see if the battery was dead and sure enough it was. Not only was it dead but the battery contact was corroded. This RDS would have been useless if I needed it and I have never really liked RDS for this very reason. I have looked off and on for a while for a zero magnification etched reticle optic (that may or may not be illuminated) that will work no matter what. I haven’t really found anything like that. I have found 1X etched reticle optics but the problem with them is the eye relief is not unlimited. Is this even the best way to go or should I go with a little magnification (i.e. 3X) There are some of the optics I have looked at: Vortex Spitfire Prism Scope: http://www.vortexoptics.com/category/spitfire_prism_scopes Burris AR Prism Scope: https://www.burrisoptics.com/sights/ar-sights Athlon Prism Scopes: https://athlonoptics.com/product/rifle-scopes-midas-btr-pr11-prismscope/ Any suggestions would be appreciated.
