Greg and Rob are right,those G5' are not what they are cracked up to be.Get the Fletcher,you won't be sorry.By the way,I do shoot with my glasses on.One thing more,I always buy the peep a little smaller so I can drill the peep out to perfectly match the outside ring of the apperture.This way,You don't have to center the apperture in the peep,it's always there(you will have to paint or magic marker the inside afterwards)...Bob
