I was there 3 weeks ago - all was normal
I was at Frontsight the week that the "seizure" supposedly happened (May 13 through 19). There were over 425 students there that weekend. All employees were paid on time (according to them) without any changes.
A receiver would be irresponsible if they shut things down, as FrontSight is certainly bringing in lots of cash. A receiver would also have to meet the obligations of the corporation if they could reasonably do so.
So I think that anyone who made a purchase will still be fine. It is taking a VERY long time to get ANYTHING from Springfield Armory these days. When I was there about 30-40 students picked up their XDs that weekend (well, they used them, and arranged to ship them to their local FFL).
This lawsuit is not about breaking laws, it is about breaking a contract. I agree that is not an honorable thing to do, but I also think that the few buyers involved in the lawsuit got "buyer's remorse" and got a (very lucky) attorney to help them out.
Until a week ago the attorney for the former Frontsight members maintained a website that talked about what was going on, and included all of the legal documents issued by the court. That site is gone, and they never showed any court order about the receivership.
The receiver, by the way, has to run things responsibly and reasonably or they too could be in trouble. Generally they would not want to rock the boat, they want to haul in all the cash they can.
As for concealed carry (the real topic of this forum) Frontsight helped me apply for my permits from Nevada, Utah and Florida. As this was just 2 weeks ago I have not received them yet.
