I shoot bullseye indoors with an illuminated target and the shooter in a darkish area. The shooter can turn on their light if they wish. How would they be in this situation? If it is very low light do you get a good square image of the front sight? Sorry, I have never handled one of these, just doing some research before a possible purchase.
fo sights don't work very well for bulls eye , you see the round fo outlined by a light black square . you may find some use for them on the issf rapid fire target , outdoors or with a well lit port . they are great for action shooting .
I ditched my FO's for Ameriglo Hacks. They are much brighter in all light conditions.
I've also found bright orange engine pain to be much brighter than FO's....
