Why anyone would want to send money and their receiver in to a company that is going through a move is hard to understand.
I can see that a person would be upset, but why put yourself through that sort of thing when you know that things are not going to be as they should be, at least for a while.
There is enough blame to go around, and some of it has to be on the company for not suspending the service at least temporarily, and on the person that took the chance, and ordered the barrel.
So it seems if you want to take the chance, then be prepared to play the games, and be aware that you will get very little sympathy here because most have heard the complaints, and rants, but where your rant will do the most good is at Remington.
Like someone said, it's worth not having to deal with all the hassle, and just go ahead and purchase a new complete rifle if time is important to you, and it won't cost that much more!
