I took aperture out of rear williams cva sight, making more of ghost ring setup. Couldn t see for chit with rear sight drilled to enlarge hole. I'm 45 and eyes just started getting weird last couple yrs. No probs shooting at 100 yds through Lyman front globe.
I use a merit adjustable peep although I've not shot it a lot yet. But I like the ability to make it small to sight in under normal daylight and can open it up during hunting in low light conditions.
