I've been having no luck myself. I've tested a 042, a 072, and a 062. All 3 make the clicking noise. The 062's clicking is loud enough that my buddy from a couple feet away could hear it. The 072 clicks, but worse yet it also makes a squeaking noise right as I fully contract the barrel to 24mm.
I am curious: Is there anyone who has decided to keep a copy that clicked, and found that the clicking disappears after a couple of weeks of use? If the clicking eventually disappears after a certain amount of twisting and/or time, I might just keep one of the copies (this lottery is tiring). If there's anybody who kept a clicking copy who is still experiencing the same amount of clicking after a couple of weeks of use, please let me know too.
