Some questions about the z-levels and the loot crates

[Roomba]

The hunting rifle can be found in one of the adventure zones (I'll leave you to discover which one in your travels) and the MD's tranq gun also works as a hunting rifle if they happen to get hunting rifle ammo. Laser/phaser guns can occasionally be found in locked safes out in space and locked crates sometimes, I think.
