IMO it will dramatically increase your accuracy. I am not sure how people even shoot the fiber optic sights?? Too bright for me. Peep sights are fully adjustable. Also pay close attention to your front sight. I prefer a small white bead. You will find out that all you need to do is focus on the front sight and the target, your eye will line up the rear aperature almost automatically. Get the larger "Hunter's peep" rear aperture for hunting. Tom.
