No but it has a Vortek PG4 kit in it. That kit as a thin steel outer guide at the trigger end. I have a more conventional ARH kit that I could try again. I tried it shortly a few years ago and I don't remember if it still made the noise. It was removed because the gun didn't make as much power as the Vortek. I'll tear it down and have a second look in there and put it back together with the ARH kit. Hopefully the noise will go away and I'll find the missing power. I'll see if I can get a better measurement of the TP. I thought that synthetic sealed Weihrauchs were 3.2mm.
Be well all

I'll be back with the results later
