My flip up leaves are stiff to move so I don't D&T them down..

Also,I do sight each one of them in at specific yardage and I use them as such..I have them sighted in at 100, 200 and 300, if I have a 4th option I sight them in a 50,100,200,and 300..This works much better for me. Not many folks do this anymore, prefering to sight the rifle in x inches high at 100 and just use the one sight. I did that for years, but I prefer to have each sight sighted in at a specific range today..Both methods work, but I think eveyone owes it to themselves to try both methods before they make a decision.
