I am using a silenced tranq sniper rifle (because why would you not?) and of course, the silencer runs out after a time. So, I called a supply drop but was told that "some items are not available because of a lack of resources". I look at the iDroid and could not find anything low or just empty.

I looked at the official guide but could not find anything about that.

As a work around, I can switch the silencer from the machine gun. But I would like to know what I am missing so I can get some more of that.

Any one encountered this and can enlighten me?

  • Did the ammo refill at the time?

  • @Jeeva: Yes, all the tranq ammo refreshed fine for both the pistol and sniper rifle. The only thing that was missing (as far as I could tell, the message did not specify which things would be missing or why) was a new silencer for the rifle. Oct 2, 2015 at 9:45
  • The only thing I can think of tranquilizer rifles specifically needing are a plant. I cannot remember which one exactly, but maybe if you don't have it they wont give you a new suppressor? Oct 2, 2015 at 13:44

    By chance was this gun customized? By this I mean was the silencer not native to that model? I had the same issue once and this was why.

1 Answer 1


I had the same thing happen to me once, this was on a gun that I had customized and added a silencer that was a grade above what I already had developed for that specific gun. To be a little bit more specific I added a level 2 silencer to my sniper rifle before I had one developed for that model. I took it from the assault rifle I had made. When I went to deploy a supply drop to myself for the first time with that it said the exact thing you noted. It only happened once as I made the upgrade to give me a level 2 silencer shortly after. It could have been the combination of the assault rifle suppressor on the sniper....or maybe I was in the process of developing the sniper with the level 2 suppressor at the time... I did not look in to it much since it worked fine the following attempt maybe a day later worth of game time. Hope this helps you.
