I'm curious what you would suggest GGW owner should have done to compensate him? I can understand the fed up aspect with the upper being damaged, that was a bad mess up that compounded the problem rather than help. But as to the paperwork issue, I'm not sure there was anything else he could have offered that would have really addressed the problem in any meaningful way. I would say the business owner's attempt at compensation was fair, or it's debatable it was at least. But whether you might argue he should have offered more, that is just a matter of coming up with a number that would be acceptable to the client as compensation for the admitted mistake. Nothing will actually rectify the mistake, as has been noted. I get the feeling that if the upper had not been damaged, we might not have ever heard of any of this. At least I suspect so, as it didn't sound like he was trying to get more out of GGW. What I read in the OPs last statement is he just isn't willing to deal with them anymore out of frustration, which is understandable. Not necessarily because he feels they owe him more (other than fixing the upper if he so desired), but more because he's tired of the mistakes.
I was thinking this as well. That a suppressor would fall into this class of controlled firearms is ridiculous and really should be changed.
