Front sight required electronic protection. I have some electronic muffs but I went ahead and purchased a pair of Sport Ear which are custom made and also act as hearing aids - I kinda blew out my ears shooting as a kid (Nobody even worried about it back then) and these have 4 settings which are custom designed to compensate for my hearing loss. Setting #1 for normal hearing, #2 is enhanced, #3 is for shooting and #4 is for heightened sensitivity so when in the wilds you have "super hearing". They instantly protect my ears from explosive sounds. It is nice to not have to worry about the muffs when I go shooting now.
