Here's a suggestion: Search this sight for "Lowell Harrier". He made peep sights for sale, at least at one point in time. Your search results will give you some information about what he did so you can replicate it if you think it will work for you. I'm not familiar with your particular rifle, but these are pretty simple and I would think, fairly universal. I need to make at least one of these. I haven't started yet, but it doesn't appear to be too difficult. PM me if you need additional information. Good luck!
