After coming to the realization that my eyes aren't getting any younger, I've been thinking about ways to keep shooting my SMR with reasonably good effect. I think a peep sight would be a big improvement, but what is the best way to proceed? I could make one that attaches with the tang screw, but what about a long bar version that goes into the factory dovetail and extends back to the tang? It would indeed be quite long, as the cut is well forward. But should be doable, with a screw for elevation adjustment and drift in the dovetail for windage. So, I am wondering if anybody here has built anything like this and what did you think? Mainly looking for inspiration as to the appearance and ways to make it look like it belongs there.
