How do I unlock the Z93 Sniper rifle?

I think a Z93 can be obtained on the mission where Jason must climb a water tower to ambush privateers (not pirates) on the first island.

I think the TS is referring to Far Cry 3, not Far Cry 4.

I think the Z93 still disappears if you exchange it for another weapon at the store. That's why I kept mine in the same weapon slot.

Yup. I remember now. After I obtained the Z-93 on a mission, I made the mistake of choosing a different weapon for that weapon slot later on. When I looked for the Z-93, it was gone. I didn't see it again for a long time.

So, once you have it early, leave it in the weapon slot.
