I just bought a YHM flip-up rear sight, and was wondering:
What is the Battle-sight Zero distance for flip-up rear back-up Iron Sights that are not adjustable for elevation ?
100 meters ? 200 ? 300 ?
I use the same zero for everything--200 meters. This gives me a very flat trajectory to 250, and maybe 10" low at 300. 300m zeros have a much more arched trajectory, and 100m zeros put the POI below the line of sight at every distance but 100m.
