I have recently been trying to use iron sights and just cant seem to ever make them work. My problem is that I am heavily visually impaired(20/EE(special book with letter twice as big as the 20/400 eye chart e),20/100). Is there any tips that I can use to make this easier as I cant put a scope on all my friends rifles and not a CC pistol. I can do fine with a big enought scope(9x40 for 50yds barely).
