I'm looking around for a generic type of rear peep sight that mounts on a picatinny rail. I have a rail for my Marlin 39A and can find an inexpensive one for my 10/22. I would like to be able to find a rear peep sight that I can mount on either one that would leave room on the rail to put a red dot if I want.
I can find peep sights for each rifle, but they are specific to the rifle. I could go that way, but the peep sight for the Marlin does incorporate the picatinny rail so I could not put the red dot on without doing a total hardware swap-out.
Anybody know of a rear peep sight that would fit the bill? I see them for AR's, but they would be too high.
