Maybe so with the peep sights you are used to using. Williams sights just ain't built thataway.
@Elderberry Never really liked peep sights,so I was never willing to spend the money for the high-priced spread. I guess you could take the biggest drill bit you could find that wouldn't completely destroy your sight,and drill it out after removing the "peep",but that seems wasteful to me. Better to sell it and then mount one of the cheapies like came on my 22 rifle when I was 10. Remove the aperture,and "BINGO!",you have a "ghost sight".
I never really "got" the whole peep sight thing on a hunting rifle to start with,since you are supposed to focus on the front sight,anyway. Let your eye do the "work". It's what eyes do.
