I obtained, with help from this forum, the proper vintage Lyman 57E rear peep site for a Model 69 model G6941R Match rifle. When I tried to adjust (sight in) the peep sight, I could adjust the windage where I needed it to be, but not the elevation. I reached the point where no more adjustment was possible. Maybe I mounted it wrong. Maybe I need to take it apart and clean it. Maybe I need to do something else. I really do not know. I have searched, but cannot find a manual, instruction, or any written material in the vintage 57E rear peep site.  

Does anyone have any advice?

Jeez, what kind of meddling AH would remove the original Lyman sight from any 69 Match in the first place?

But to your question:  does your gun still have its original 93A front sight?  If that’s been replaced by a lower front sight, you might run out of elevation adjustment on the 57.

Is your replacement 57 a 57E OR 57 EW?  The locations of the mounting holes differ, which changes the point of impact somewhat, though it would seem surprising if it changed it to the extreme degree you described.

No instruction manual for any Lyman rcvr sight is needed, except that because the earlier models lacked the “arrows” indicating “up” & “down” which later versions have, users have to figure that out for themselves by trial & error.  (I can’t remember, so I make my own “arrows” with a pencil.)

As Clarence mentioned, the elevation is easy to adjust and the front sight is the most likely cause.  I did put a copy of they Lyman adjustment instructions in the book on the Model 69 but am travelling and don’t have access to them. 

What range are you trying to sight it in?

You didn’t say if the gun is shooting high or low.  There is a small set screw designed to stop the sight from being lowered past a previously determined height.  If its shooting too high look and see if that little adjusting screw is the problem. It may be screwed in too far and not allowing the sight to be lowered. It is usually located just in front of the elevation knob.  RDB
