Exactly the same problem i have with fiber optics. The fibers that are on the CVA's now use 2 bigger fibers on the rear and a smaller front red dot on the front sight. That so far had been one of the easiest fiber sights that i could use, Along with the truglo's. The williams sights like that ones on my fathers hawken and the mountain stalker are huge and they just get blurry @ 100 yards. I really prefer the small optic up front.
