A few years ago I had an eye injury resulting in an inability to clearly see the red dot in my optics in bright daylight. I can see the etched reticle in my Vortex Viper just fine and in low light the red dot is good, but my department won’t let us use magnification on our rifles. The only sight I found with etched reticle, red dot and no magnification looked like something for an airsoft gun. Suggestions for a quality sight for my AR?
