Just trying to get a feel here.... at what distance would you guys NOT use the red dot because of sheer visibility issues while acquiring your target? For me its around the 75 yard mark. My eyes are not great but not horrible...and anything beyond 75 yards my eyes totally blur the target area. If I ever get the funds to build a long distance AR I will probably get a 20" barrel and a 10-12x magnifier scope for anything beyond 75-100 yards. Can any of you actually hit a target accurately using a red dot anywhere from 75 yards on? My groups were straggly and pretty scattered....around 10"
