I would look into adding trijicon to the list. I know very little about them but they seem to be a viable option. Pulling up black crosshairs on a coal black bear is definitely a weak link to a well placed shot. Between my son, daughter and myself we have killed 8 bears and those shots 29 minutes after sunset can be a challenge even at close range. You are on the right track with illumination. Good luck on your hunt
