Did you get the fitted hard foam custom made?
I bought on eBay military grade foam, traced with a marker around the components of the rifles, and cut carefully with a sharp kitchen knife.
The reason why I did not use the Pelican soft foam is that it is not hard enough to maintain in place heavy components (it is too compressible). Cut-to-shape military grade foam prevents anything from moving inside the case when it is rough handled.
The trick is to cut along the side of a 3 feet steel ruler to go straight, and to be careful to hold the knife vertical so that the cuts are not slanted. You can clean residual marker with medical alcohol after you cut
