Gonna rock the boat here, but I'd have to say a Freak. I had a freak for ages, without any bother but was pursuaded to swap it for a Pipe kit. With the pipe, I couldn't have hit a lake if I was sat on the bed, honestly it was shocking. It was actually less acurate than the standard XMag barrel. The freak, by comparison was ball-on-ball accurate (with an AA front) & very rarely did I get barrel breaks. The Pipe was a real let down.
