I’m no Olympic shooter nor have I spent any time getting familiar with tacticool shotguns (though i have fired an M4 on a couple occasions). That said I have shot a crap-load of dove, quail, chucker, station 1 hard rights and station 8 high houses. In none of those situations would a rear sight have served any purpose. If it did every competitive shooter on the planet would have one. I have to think a softball (at best) sized bird flying 50mph is WAAAAAAAYYYYYY harder to hit than a 200 pound bad guy moving 6mph. Use some common sense.
Drop the mic! Winner winner!
