Appreciate your post. The build referenced here was 2017; I've since switched to the Accu-washer system as well for greater ease. I don't see where 20 ft. lbs. of torque to install/remove a muzzle device would undo 150 lbs. of barrel extension/barrel torque. As LRPFF52 notes, issues can occur with the nitriding process. Or, torque was not proper with the barrel extension and barrel to begin with. PF is taking care of the issue to their credit.
Regardless, I have since modified muzzle device install/removal to only clamp the barrel in a vise (with soft jaws or something similarly suitable). I actually have a portable vise platform wherein I can still use a reaction rod while also clamping the barrel with a main vise -- yes, overkill, but it secures everything rock solid at both ends.
