I bought this barrel kit from my boss shortly after I got my stock cocker. The accuracy immediately improved, but the biggest thing I noticed was the noise reduction. You really cannot hear anything from about 15 feet away. As accurate as the Freak kit, and much quiter than the Evil Pipe. Kind of hard to find though, the only place I've seen it is on the MacDev website, www.macdev.net
This kit provides tourneyy caliber performace for a frec-ball price. An all around great kit, from the value to the performance.
