That sucks Dr., sorry to hear about it.
I just checked the 627-5 V-Comp PC I just got and it's forcing cone and lead-in machining looks just fine. Sounds like you got a very poor example of QC, with a strange number of weird, unacceptable build issues? I know it's not what you want to hear, but except for the lack of any of the claimed PC custom action tuning on a $1600 PC gun, the build quality, fit and finish on the rest of the gun is top shelf. I also would demand a replacement weapon.
