You do exactly what you say with an Acog, but there is a reason the LPVO has gained such a large following in a relatively short time. The ability to turn it to very low or even zero magnification when in close quarters gives it a distinct advantage over a fixed four power optic.I thought you shot the ACOG up close with both eyes open, https://www.trijicon.com/our-story/bindon-aiming-concept
It's not perfect, but it is workable. And the ACOG is superb at distance, plus obviously built like a tank.
