The peep is 1/4 inch as recommended by the sights instructions. The 28" draw is right on. I think the peep location is OK, I can comfortably line up the site ring, see the level as well as all the pin tips....I think the problem is my eyeglass prescription, the readers are very low on the progressive lenses
II have 3 levels in the lenses. I'm heading back to the shop, I found out this morning that they sell the verifiers and clarifiers and have them in stock. Gonna play around and see how it plays out.
