I tend to prefer a high quality drag bag, lighter in weight yet almost the same protection of a hard case. Some of the high quality drag bags are capable of packing a rifle, shotgun and pistol all at the same time so they are well padded with plenty of pockets for extra mags, suppressors, etc.
I use a model from Voo-Doo Tactical for my Barrett, and my son has one from Midway USA.
