A rifle can vary an awful lot in length so folded/collapsed lengths of said guns will be needed.
Generally though, best to get said measurements yourself and opt for at least a half decent brand. On the one hand this isn't something you'll use in game, but equally you don't want a cheap POS that'll maybe drop your prize possessions on the car park concrete if the chinese kid who did the sewing made your particular bag in the last hour of his 14hr shift.
I recently got the 8fields 90cm padded case. Really like it. Holds a trident pdw, ares honey badger and my pistol. Also got a nice big pocket that holds my mags and batteries
