Sweet! I had a Furious/iFit on my S6.5 (bought used didn't come with a barrel) and it was great then I used BDazl's S6.5 the other weekend and it was incredible. It seemed a bit louder than mine, but it seemed to shoot flatter, if that makes any sense. I don't care about sound signature, it's hard to track a pump by sound. I much prefer the accuracy.
