The rifle does have a fixed rear sight and a foldup leaf with it.the "peep sight" has a really small hole. the reason it looks bigger is it is adjustable for both rear sights. right now it is aligned with the shorter fixed sight and will not work with the taller fold up sight without adjustment.
Hope this makes it clearer and Thank You for the information! I was unaware of this different concept on the sights. was wondering why most the venire sight i have had the rear sights removed! now it makes more sense to me.
