Medium gun parts sit at the center of ARC Raiders’ weapon economy. Any rifle or similar weapon that fires medium ammo depends on them for crafting, upgrading, and repairs, so running out will stall your entire loadout progression.
What Medium Gun Parts are and why they matter
| Property | Value |
|---|---|
| Item type | Topside material |
| Rarity | Rare |
| Used for | Crafting, upgrading, and repairing weapons that use Medium Ammo |
| Weight | 0.4 |
| Stack size | 5 |
| Sell price | 700 coins |
Any time you push medium-ammo weapons like Osprey, Tempest, Torrente, or Venator into higher tiers, medium gun parts are part of the bill. They are also used when repairing durability, which means you are constantly trading them between keeping current guns functional and investing in future upgrades.
Where medium gun parts come from
There are several ways to feed your stockpile, each with different tradeoffs in time and flexibility.
| Source | How you get them | Notes |
|---|---|---|
| ARC enemies | Loot from destroyed ARC units such as Bastions and Bombardiers | Standard combat drops while you play. |
| Scavenging | Search containers in raid spaces | Part of the general loot pool on the topside maps. |
| Crafting | Convert simple gun parts at Refiner II (blueprint required) | Gives you controlled, repeatable access. |
| Recycling | Break down weapons and gear | Indirect source; often used to generate simple gun parts first. |
| Celeste | Buy directly from the trader in Speranza using seeds | Daily-limited safety valve when you come up short. |
In practice, most players lean on a mix of combat, scavenging, and crafting. Direct purchases from Celeste are useful when you are a few parts shy of an upgrade, but the small daily quantity is not enough to sustain a heavy medium-weapon focus on its own.
The medium gun parts blueprint and Refiner II
Medium gun parts have their own crafting blueprint attached to the Refiner II workbench. Unlocking and learning this blueprint is what turns simple gun parts into a reliable input instead of a dead-end currency.
| Blueprint | Workshop | Recipe | Lootable | Quest reward | Trials reward |
|---|---|---|---|---|---|
| Medium Gun Parts | Refiner 2 | 4 × Simple Gun Parts → 1 × Medium Gun Parts | Yes | No | Yes (via trials loot pool) |
Once this blueprint is learned at the Raider Den, Refiner II gains a permanent recipe: feed four simple gun parts and receive one medium gun part. That exchange rate is fixed and effectively defines the value of medium gun parts against everything that feeds into simple gun parts, including recycled weapons.
Blueprints themselves sit inside the general scavenging and trials reward pools. Any blueprint you pull needs to be “Learn and Consume” in your inventory before the recipe shows up on your crafting benches, and unwanted duplicates can be sold for 5,000 coins each.
How to farm the medium gun parts blueprint
The blueprint is not tied to a specific quest. It lives where most crafting unlocks live: in high-value containers, drops, and trials rewards. Blueprint drops are technically possible from any loot container, but several types tend to be more productive when you are blueprint hunting:
| Where to focus | Why it helps |
|---|---|
| Air supply drops and probes | Common source of weapon-part blueprints, including light, medium, and heavy gun parts. |
| Security breaches and lockers | Security-focused rooms and lockers can roll weapon and weapon-part blueprints. |
| Raider caches | High-value, time-limited caches with strong blueprint loot pools, often featured in cache events. |
| Ammo, weapon, med, and utility crates | These crate types have elevated blueprint chances compared with basic world clutter. |
| Trials | Once you reach level 15, three-star trials objectives can award blueprints from the scavenging loot pool. |
Night variants of maps are particularly efficient for blueprint runs. Night raids boost the chance for higher-rarity loot by a large margin, which directly improves your odds of pulling rare items like gun-part blueprints from the same container types.
Within a raid, the reliable way to stack these containers is to prioritize keycard-locked rooms and breachable doors. The more friction a room presents, the more likely it is to contain the higher-end crates and lockers that roll blueprint drops.
Using medium gun parts in weapon upgrades
Once the parts themselves are flowing, the bottleneck becomes how many medium weapons you are trying to push up the ladder. Medium gun parts sit in the upgrade chains of several rifles and marksman weapons.
| Weapon upgrade | Workshop | Medium gun parts required | Other key materials |
|---|---|---|---|
| Arpeggio III → IV | Gunsmith 1 | 2 × Medium Gun Parts | 1 × Mechanical Components |
| Osprey II → III | Gunsmith 1 | 2 × Medium Gun Parts | 1 × Mechanical Components |
| Osprey III → IV | Gunsmith 1 | 2 × Medium Gun Parts | 1 × Mechanical Components |
| Tempest II → III | Gunsmith 1 | 3 × Medium Gun Parts | 1 × Advanced Mechanical Components |
| Tempest III → IV | Gunsmith 1 | 3 × Medium Gun Parts | 1 × Advanced Mechanical Components |
| Torrente II → III | Gunsmith 1 | 2 × Medium Gun Parts | 1 × Mechanical Components |
| Torrente III → IV | Gunsmith 1 | 2 × Medium Gun Parts | 1 × Mechanical Components |
| Venator II → III | Gunsmith 1 | 2 × Medium Gun Parts | 1 × Mechanical Components |
| Venator III → IV | Gunsmith 1 | 2 × Medium Gun Parts | 1 × Mechanical Components |
As soon as you chase multiple medium rifles at once, the cost adds up quickly. That is why players often feel medium gun parts more acutely than light or heavy early on: light guns are cheap to push, and heavy weapons tend to be one-offs or used situationally, while medium options are your everyday workhorses.
There is also the base-crafting layer. At Gunsmith III, the blueprints for weapons like Osprey, Torrente, Tempest, and Venator all demand medium gun parts as part of their initial recipe, not just the later upgrades. Medium gun parts are the fabric of the entire archetype, not just the tuning knob.
Recycling and salvaging medium gun parts
Medium gun parts can be broken back down into simple gun parts, but the return is intentionally lossy. That design makes sense if you think of medium gun parts as a refined product.
| Action | Input | Output | Use case |
|---|---|---|---|
| Recycle | 1 × Medium Gun Parts | 2 × Simple Gun Parts | When you are overstocked on medium and need simple parts for other recipes. |
| Salvage | 1 × Medium Gun Parts | 1 × Simple Gun Parts | Lower-yield option, typically used when extracting value from damaged gear. |
Since crafting medium gun parts costs four simple gun parts, recycling or salvaging them is a one-way value loss. That is deliberate: the system gives you a safety valve when your inventory is skewed, but it prevents free profit loops. It is usually better to recycle excess blue weapons into simple gun parts directly rather than crafting medium parts just to break them down again.
How traders and seeds fit into the picture
Celeste in Speranza sells a small number of medium gun parts per day for seeds. This is meant as a pressure release rather than a primary supply line. The daily cap is low enough that you cannot sustain an aggressive medium-weapon upgrade plan on trader purchases alone, but you can use them to patch gaps when you are one or two parts away from a key upgrade.
Seeds themselves are a shared currency across multiple trader offerings, so every medium gun part you buy is a choice against other progression items. That trade-off is another reason the Refiner II blueprint is so important: once learned, seeds can be reserved for rarer materials while your gun-part economy runs mostly on loot and recycling.
Medium gun parts start out feeling scarce, especially right after you pick up blueprints like Torrente or Osprey and want to rush them up the ladder. Once the Refiner II blueprint is in place and you lean into high-value containers, night raids, and trials for blueprint drops, they shift from hard wall to manageable constraint. At that point the real decision is not how to get medium gun parts at all, but which of your medium weapons is worth feeding first.
