What are some of the rarest items?

Thank you in advance.

Even though I don't play the game, after reading through a lot of stuff and watching videos of it (My way of making sure i want it before buying it). It's probably bombs and explosive charges. since they can only be found from airdrops or dead players that found a airdrop

It all depends really, some of the Rad towns always have good loot, some are inconsistent.
Items I've struggled with finding the most are:
M4/Bolt action rifles
Explosives/Explosive charges
Kevlar armour
Research kits
Metal construction parts can be pretty hard to find too
Other than those items (Unless I've missed something) everything is pretty easy to find by scavenging and killing zombies, or you can go down the bandit route and raid buildings for supplies.

Boltaction rifle and Silencers. Explosives only come from air drops. C4 is also pretty rare.

What StorAxis and ficti0nalhero said above. What I will also add is the "Radiated shirt" (or how it is called), that one is the only item that is missing from my "Radi" clothes collection.

Weapons:
Bolt Action Rifle (the only sniper weapon in the game, made less useful due to the lack of scopes)
M4 (The most desirable weapon. Has the longest range bar the bolt action, is fully automatic and deals a high damage per shot)
MP5 (A submachine gun which uses 9mm ammo. I would argue pretty rare to find. Less damage and range than the m4, but less recoil and a higher rate of fire)

Armour:
Kevlar set (the highest bullet and melee protection available. From my experience, the blueprints for it are found rarely from zombies, with the vest being the rarest piece)

Structural:
Metal building parts (except for the door and window bars which you can make from the start. I believe found only via air drops and very rarely from zombies)

Other:
Explosive charges (found via air drops or very rarely from zombies and crates)
Explosives (used to craft explosive charges if researched. Can also be researched, but must be found in air drops)
Supply drop beacons (Very rare, only in air drops. A grenade that lets out green smoke and calls an air drop to that location)
