Best way to sight in a Bushmaster M4A3??
I finally got to fire my M4A3 at the state game range this weekend. Like a fool, I forgot the front sight post adjusting tool. Now, it's been awhile since I had to qualify for Uncle Sam's Misguided Children, so, I was wondering if anyone had any good ideas as for the best way sight in my rifle. As it stands, once I adjusted the rear sight windage knob 3 clicks to the right, I was hitting center mass, but 6 inches high. Any idea as to how many clicks I should adjust the front sight post?
