If you can stand the pain, an ACOG would be my choice. That rifle will reach out so I would hesitate to mount a dot designed for CQB. But then you can add a magnifier to your dot. If up close is your cup of tea and you are on a budget I have been impressed with the Holosun 510c, about half the cost of a Trijicon holographic. Try some of the dots to see how they work with your eyes. Dot colors are also a personal preference. Some folks with astigmatism have issues with seeing the dot sharply in holographic sights. Find something that fits you, everybody's experience is different and dot choice is personal. Good luck on your quest.
