My brother has poor eyesight. He asked if I would help find him a scope with an illuminated red dot and magnification. I have been able to find scads of non-magnifying units, or units with magnification but still only intended for relatively short range (100 yards or less). I found one make called Mueller with which I have no experience. Has anybody else here used them? Anyone know of any other units that could help him shoot out to at least 200 yards?
