I have a Remington 870 with a folding stock and a couple of large pistols with buffer tubes on them. I have cases that fit some of them in a pinch, but haven't had much luck finding one that fits them well. Has anyone found a nice hard sided case that would fit an AR pistol or folding shotgun or AK? Have you had a custom case made? If so, were there any features that really appealed to you?
