Great rifles. Best sights ever on a military rifle.
Positive clicks. You can be assured one click per moa, all the way through the range of the sights.
I got mine in the early 80s. First time I shot it was at a rifle matches. First rounds were the two sighters offhand at 200 yards.
Got my sight settings then and they haven't changed at all. Windage or elevation.
I've shot the crap out of mine over the years, then last month I shot the CMP Garand Match at Cody WY. It still shoots.
