Do other people get rifles with bad comp tubes?
When working on my own springers have found a few bad tubes: some have tight/high spots in the middel of the tube, and some have ridges down at the bottom that chew up piston seals.
I'm not talking about Chinese guns, but German and British guns that are supposed to be good; a HW80 had a sharp ridge at the bottom, several Supersports seem to be oval and leak lubricants past the seal, a Tx200 with bulges, and the list goes on...
Do other people get them too, or is it just me?
