USNCop,
what is wrong with the case that the QB-57 came in?
I took out the foam, put in a new foam with the current dimention cut outs.
Then i cut off the latches that it came with, and screwed on buckles and straps that go all around, and hook to the buckels..and now, I have a reliable, and pretty neat case for it.
Message me your email and I can send you pictures.
