The Medium Gun Parts Blueprint is one of the most-searched, least-understood unlocks in ARC Raiders — and for good reason. Medium Gun Parts are the crafting material that keeps most mid-tier and rare medium-ammo weapons in your stash running, but the blueprint that lets you make them yourself doesn't drop from the lockers most players grind. Cracking drawers and weapon boxes match after match will get you almost nothing; the people pulling four in a single run are farming a completely different container. This guide front-loads the exact answer — where the blueprint actually drops, how to find those containers fast, and what the recipe does once you learn it — then breaks down every other way to keep Medium Gun Parts stocked.
TL;DR — Medium Gun Parts Blueprint quick answer
- Where it drops: the Medium Gun Parts Blueprint rolls from Raider Caches / Raider Containers, the same loot pool as weapon blueprints — not from medical bags or standard drawers (arcraiders.wiki).
- How to find caches fast: Raider Caches emit a distinct ticking / clock-like sound as you approach. Wear headphones, sweep the map perimeter, and prioritise night raids — community farmers report finding far more caches in dark, low-traffic runs.
- Another shot at it: the blueprint is in the scavenging loot pool, so it can also appear as a Trials reward — a second avenue alongside cache farming (Trials rewards are tier-based and random, so it's another chance, not a guaranteed unlock) (arcraiders.wiki).
- What it unlocks: once learned (Learn & Consume), you get a recipe at the Refiner (Level 2) that turns 4× Simple Gun Parts → 1× Medium Gun Parts (arcraiders.wiki).
- The material itself: Medium Gun Parts are a Rare Topside Material — weight 0.4, stack 5, sell 700 Coins — used to craft, upgrade and repair medium-ammo weapons.
Read on for the full breakdown: what Medium Gun Parts do, every blueprint source, the fastest cache route, and the recipe math that makes the blueprint pay for itself.
What are Medium Gun Parts in ARC Raiders?
Medium Gun Parts are a Rare Topside Material — "assorted spare parts used for rifles," in the wiki's words. They sit in the middle of the gun-parts progression chain: above Simple Gun Parts, below Advanced/Heavy components. The ARC Raiders wiki is blunt about why they matter: "Medium Gun Parts are used to upgrade, craft, and repair Weapons" (arcraiders.wiki).
If you run mid-tier or rare Medium-Ammo weapons like the Torrente LMG, Osprey sniper rifle, Venator pistol or the budget-favourite Canto SMG — the Canto's craft alone needs 3× Medium Gun Parts — you will burn through them constantly. They feed many of those weapons' crafts, tier upgrades at the Gunsmith, and repairs after a rough raid. (Some basic Medium-Ammo guns like the Rattler still upgrade with Simple Gun Parts, so it's the mid-tier-and-up weapons that drain your supply.) A weapon you can't repair is a weapon you eventually lose, which is exactly why so many mid-game raiders hit a wall: they have the guns, but not the parts to keep them alive.
Quick stat block for the material:
| Property | Value |
|---|---|
| Rarity | Rare (Topside Material) |
| Weight | 0.4 |
| Stack size | 5 |
| Sell price | 700 Coins |
| Recycles into | 2× Simple Gun Parts |
| Salvages into | 1× Simple Gun Parts |
| Used for | Craft / upgrade / repair medium-ammo weapons |
The blueprint is a separate thing from the material. You can loot Medium Gun Parts directly all day — but the blueprint is what lets you manufacture them on demand, which is the real time-saver once Simple Gun Parts start piling up in your stash.
Where do you find the Medium Gun Parts Blueprint?
This is the part most guides get vague about, so here is the precise answer.
Raider Caches are the primary source
In ARC Raiders, blueprints follow a container-type loot pool: weapon and gun-part blueprints are tied to Raider Containers / Raider Caches, while medical, augment and utility blueprints come from their own container families (arcraiders.wiki). The Medium Gun Parts Blueprint lives in that weapon/gun-part pool, which is why grinding random drawers feels so dead — you're rolling on the wrong table.
The catch is that the Medium Gun Parts Blueprint shares its pool with every other gun-part and weapon blueprint, so you're fighting RNG to roll that specific one. Community farmers consistently report the same fix: stop opening everything, and start hunting Raider Caches specifically. One raider on r/ArcRaiders described pulling four blueprints in a single night run doing exactly this — a result that's only possible when you target caches instead of stumbling on them.
How to find Raider Caches fast
Raider Caches are not marked on your map by default, which is why players with hundreds of hours still say they've only found a handful. Two habits flip that completely:
- Listen for the ticking. Raider Caches give off a distinct clock-like ticking sound when you get close. Plenty of players admit they used to hear it, assume it was an enemy mine, and run the other way — costing themselves the exact loot they were grinding for. Wear headphones and move toward the sound, not away from it.
- Sweep the perimeter. Community farmers report caches skewing toward the edges of the map rather than the dense central POIs (treat this as route advice, not a guaranteed spawn rule). A loop of the outer ring on each map tends to turn up more caches than diving the contested middle, and it keeps you away from third-party fights.
- Raid at night. Night raids run quieter and darker, so you can clear cache spawns without constant PvP interruptions. The biggest community hauls are almost always reported from night runs.
There are community interactive maps that mark known Raider Cache spawn points per map — pairing one of those with the audio cue is the fastest possible approach. ARC's own 1.33.0 patch notes even called out improved Raider Cache audio cues, so the ticking tell is more reliable now than it was at launch (arcraiders.com).
The Trials reward path (a second avenue)
Because the Medium Gun Parts Blueprint sits in the scavenging loot pool, the wiki notes that scavenging-pool blueprints are eligible to appear as a Trials reward (arcraiders.wiki). Trials rewards are tier-based and random, so this isn't a guaranteed unlock — but if you're already pushing weekly Trials for ranks and gear, it's a second avenue at the blueprint running in parallel with your cache farming, rather than relying on caches alone.
How do you craft Medium Gun Parts once you have the blueprint?
Learning the blueprint is Learn & Consume: you open it from your inventory, confirm, the blueprint is consumed, and the recipe is yours permanently. After that, head to the Refiner in your Speranza workshop.
| Recipe | Station | Result |
|---|---|---|
| 4× Simple Gun Parts | Refiner Level 2 | 1× Medium Gun Parts |
A few things matter here:
- Refiner Level 2 is mandatory. A Level 1 Refiner won't run the recipe — upgrade the station first or the blueprint sits useless.
- Simple Gun Parts are abundant. You can't craft Simple Gun Parts (there's no blueprint for them — that's a confirmed dead end), but you get them constantly from recycling and salvaging weapons and parts. That makes them the perfect feedstock: convert your junk into the mid-tier material you actually need.
- Crafting beats farming for volume. Once your Simple Gun Parts pile up, refining them is faster and far more reliable than hoping a Bastion or a locker coughs up Medium Gun Parts. This is the entire payoff of the blueprint: turning stash clutter into ammo-grade repair material on demand.
What else drops Medium Gun Parts? (every other source)
Even before you unlock the blueprint, you can keep a working supply through these routes:
| Source | Details |
|---|---|
| Scavenging | Found in Raider and Security containers topside |
| ARC enemy drops | Dropped by the Bastion and Sentinel machines |
| Vendor | Sold by Celeste — limited stock (around 3 per day) |
| Quests | Rewards from A Balanced Harvest (3), Flickering Threat (5), Straight Record (5), Turnabout (2) |
| Recycling | Recycling certain weapons/parts returns Medium Gun Parts |
Source: arcraiders.wiki/wiki/Medium_Gun_Parts. The takeaway: the material has many faucets, but the blueprint is the only thing that turns your endless Simple Gun Parts into a self-sufficient supply — which is why it's worth chasing even if your stash is full of looted parts today.
Best Medium Gun Parts farming strategy
Put it together into a routine:
- Build a Simple Gun Parts surplus. Recycle/salvage every weapon and gun-part you don't need instead of selling it. Each Medium Gun Parts recycles back into 2× Simple, so over-crafting is cheap to correct.
- Chase the blueprint on two fronts: push weekly Trials (it can appear as a tier reward) and farm Raider Caches (perimeter loop + audio cue + night raids). Both are RNG, so working them in parallel beats relying on either alone.
- Upgrade your Refiner to Level 2 early so the recipe is live the moment the blueprint drops.
- Extract with it. The single most painful mistake — echoed across r/ArcRaiders — is finding the blueprint, then dying or getting ratted before extraction and losing it. If a Medium Gun Parts Blueprint drops, play it safe, get it in your safe pocket where possible, and extract. A blueprint you didn't bank doesn't count.

Frequently Asked Questions
Where does the Medium Gun Parts Blueprint drop in ARC Raiders? It rolls from Raider Caches / Raider Containers, the same loot pool as weapon blueprints — not from medical bags or standard drawers. Because the pool is shared with every gun-part and weapon blueprint, you're fighting RNG to roll that specific one, so targeting caches (and Trials rewards) beats opening everything in sight.
Why can't I find Raider Caches? They aren't pinned on your map, but they emit a clock-like ticking sound as you approach — many players mistake it for a mine and avoid it. Wear headphones, sweep the map perimeter, and run at night for quieter, more productive sweeps. Community interactive maps also mark known cache spawns.
Is there a Simple Gun Parts blueprint? No. There's no blueprint to craft Simple Gun Parts — you get them from recycling and salvaging. The Medium Gun Parts Blueprint then lets you refine 4 Simple Gun Parts into 1 Medium Gun Parts at a Refiner Level 2, which is the whole point of unlocking it.
What are Medium Gun Parts used for? They craft, upgrade and repair medium-ammo weapons like the Torrente, Venator, Osprey and Canto. Without a steady supply you can't keep those guns repaired, so you eventually lose them — making Medium Gun Parts a core mid-game bottleneck.
Can I just buy or earn Medium Gun Parts without the blueprint? Yes — they're sold by Celeste (limited daily stock), drop from Bastion and Sentinel ARC machines, come from several quests, and loot from Raider/Security containers. But the blueprint is the only way to manufacture them on demand from your surplus Simple Gun Parts.
How much do Medium Gun Parts sell for? 700 Coins each. They're a Rare Topside Material weighing 0.4 with a stack size of 5 — generally better kept and refined/used than sold, given how often you need them for repairs.
