I've had to reseal my Edge a couple times. Have had it since they first came out.
Was your issue a leak or something else?
Far as QC... I couldnt tell you. I consider the AF line to be one that will require tinkering on a regular basis. In my opinion, they are not a buy, pick up and shoot any time gun like many of the European guns. They are more of a buy, tinker, shoot, tinker, shoot, get frustrated, put away, take out, tinker, shoot gun.
I can say this with some experience as I have 6 of them.
All those who believe in psychokinesis, raise my hand.
Good judgment comes from experience; experience usually comes from bad judgment.
