I was looking into getting iron sights for my 50 cal but i havent been able to find any kind of iron sights besides ones for ar15/10s (223s/308s) and stuff like flip up or fixed position iron sights. I used to have an M82 and that came with a very nice set of back up flip up irons sights. If i could get something like that for my current 50 bmg rifle (AR-50) I would like to do that. I really just like using old fashioned irons. You dont have to worry about batteries but it takes quite a bit more skill than using glass magnification. And its just nice to have as a backup.
