You probably already know that sights are available for both the Bolt guns and the AR type.
These aperture style sights take most of the guess work out of lining up a long range shot. They are pricy when you consider the additional cost of the rear aperture and the fore sight assembly. However, just about anyone can be taught to hit a six inch circle on a regular basis from 600 yards.

The sights on my 30 Cal Target rifle are simular to these. I don't have a bit of trouble hitting the X Ring.
Been a long time since I have attended a high Power or even a Leg Match......:o) I get to a shoot house once or twice a week handgun and trigger time on a M4 carbine or M1A as well yet I miss the Whittington Center in NM.....Good bunch of folks. When I was active duty I had a Det Commander that let us go to Raton and compete all the time . That I miss !
