I have marks on my sight bars. I put dots of white paint (whiteout) on my sight bars. After it's sighted in, I make marks with a fine tip marker. If the marks are all lined up, the sight hasn't moved. It's easy to check.
I still shoot every week to make sure nothing else has change. (rest, nocking point)
I use a Hindsight so I don't have to worry about the peep moving.
