I decided to fine tune my Kibler .32 yesterday and kill some squirrels, I found I can no longer see the rear sight well enough to shoot consistently, for me now it is an unrecognizable black blob. This rifle came with the standard young eye rear sight dovetail about 4" behind the entry pipe. When I build a gun I move the rear sight over the rear entry pipe so I can see it better.
I mentioned my dilemma on the ALR site, one guy offered this solution, I am going to make one this afternoon and see if it works for me. I have 72 year old eyes, the rear sights of my guns have been disappearing a little at a time over the last 10 years of so.
