These AR Stoner barrels really love the 120g Barnes. You can get 2700fps from a 24in barrel with 28.8 to 29.1gr of AA2520. I'm using 29.3 to to get my gas system working in good order on my 18in barrel but for velocity sake i could be down at 28.8gr of AA2520. The extra velocity really puts the 140gr pills into play as well. They are a little on the porky side and not as accurate at the high end custom rifles but do pretty darn good for the price tag.
