Good points.
A few buddies of mine keep telling me “accuracy doesn’t matter in a fight”. Being one who only will shoot a tight grouping rifle, I never wanted to believe them.
In fact, my AR A2 upper is right about an inch at 100 yards. Iron sights right now, and from a bench. Want to get a small optic for the carry handle mount.
I have an EOTech on my flattop, because the rifle is intended for short and fast suburban scenarios.
But if I had my druthers, I’d put an ACOG on it for longer range work.
