Fit a ghost ring rear sight and shoot both eyes open or a Aimpoint, same thing both eyes open
"In rough terrain, foul weather, poor light and high levels of stress even the most experienced hunter will be put to the test. Tests have proven that the single red dot reticle is the fastest on target, providing the greatest hit probability with moving targets.
With an Aimpoint® sight, you never have to worry about centering the dot inside the sight. Once you see the dot on your target, you’re ready to shoot. Other red dot sights with substantial parallax can cause you to miss by as much as 30 cm (12 inches) at a distance of only 45 meters (50 yards). That can mean the difference between a clean kill and irresponsibly wounding an animal or missing it completely.
Aimpoint® red dot sights give you increased aiming confidence and allow you to remain on target and shoot with both eyes open. If you are a sports shooter, in a competition fractions of a second count and quick target acquisition is essential. Whether you have a rifle, shotgun, handgun, black powder rifle or bow, Aimpoint has a sight for you.
