I installed a rear peep on my ML long before I had cataract surgery. Where I lived at the time the ML clubs and four rondys a year I attended had many shooters who used peeps. Where I've moved to I only found one club that allows a rear peep. The rest are hard core "open iron sights only" which really limits my shooting opportunities. I have found evidence that a rear peep is actually historically correct but oh well.
