This is a great barrel i had it on my a-5 and was shooting a tree from probaably about 30 ft. away. The balls were hitting in the exact same place every time. 3-4 spread. I have nvr had my a-5 chronoed so i dont know what i was shooting at and i dont have a reg. so it does show that it was all the barrel. This is a great barrel, very consistent i would deffinetly reccomend it.
