5.11 Tactical & Blackhawk(started by a retired US Navy SEAL) have good kits & cases.
The Pelican line is good too. They are airline/TSA approved & come in many colors-sizes(including clear).
FWIW; I always use a Bore-Store treated bag as a 2nd layer of protection when I go to the field or range. They aid in preventing nicks, scuffs, etc.
