Well sorted out design - Vism Rifle Case/Shooting Mat, 48in

Durable, does what I bought it to do with an M1-A.

Plenty of places to store your possibles. In fact maybe too much many, as you can stuff a tonna things inside, then strap on molle bags and end up with a 30# pack to schlep out to the field with if you're not careful. At least the back pack straps are up to that kind of load should you need them.
