Sighting in process for flip up rear sight

[foresterdj]

It is a long time yet until my winter project, which is a .62 Jaeger with a Rice barrel, cherry stock and iron hardware. I usually use peep sights, but might put a flip up rear on this one. In fact, I hope to get one of the ones recently in the for sale section. These come with a smooth slightly curved top line on the fixed and flip parts, so you can file v or square notch as you choose and then between filing of rear and or front, adjust for elevation.

So my question; Is there any rationale or reason to sight adjust for the flip up longer range part, or the lower fixed part first, then do the other?

Never done it  but am thinking that it might be easier too line up both notches before you install the basses. Maybe they are Lined up when you buy them???

I misunderstood the question.
I would sight in the close range first, then the longer range flip-up sight. This is how all such sights are sighted in as far as I know.
Some rifles with sights such as these, have never had the longer range leaf or leaves sighted in, so the close range sight must have been done first.
