I run an Armilite ar 10 A2 in 308, & I have a Springfield Armory 4-14-56 2nd generation government Model scope. It is set up with a ballistic plex reticule built specifically for the 168 grain A-max, it reticule is set up to fire out to a 1000 meters. It is quite the package, & has taken quite a few deer & to many coyotes to count. The only down side to the gun is the fact that it weighs about 12 lbs unloaded...
