There's not a better way to get more proficient with you ar. Your in a good state for 3 gun or simply action rifle matches which I like more than 3 gun since it's my best weapon. The guys that attend these are always gentle with the new guys, they will show the ropes. Also, there's always a few guys shooting irons so optics aren't necessary unless you have eyes like mine.
