Some attachments in ARC Raiders feel less like loots and more like trophies. Kinetic Converter, Horizontal Grip, Silencer 3, and Anvil Splitter are the big ones. You can't reliably craft them, their drop rate is low, and once you finally get one, you usually think twice before putting it on a gun.

After repeated runs and comparing route results across maps, one thing stands out: these attachments are not purely random, but they also don't seem tied to just one magical room. Certain locations clearly perform better, especially spots with the right container types and tight loot density. That's where we should be farming.

How These Attachments Seem to Spawn

From testing and player-reported results, the best working theory is simple:

• Attachment-capable containers may all have a chance to roll rare attachments
• Some breach rooms and residential-heavy areas appear much more reliable
• Silencer 3 feels noticeably rarer than the other three
• Fast, repeatable routes usually beat full-map clears

This matters because it changes how we farm. We're not just hunting one room — we're targeting the best container clusters.

The short version: if you loot one Silencer 3, don't treat it like a common attachment. It isn't.

Best Maps and Locations

Here are the most useful spots right now, based on consistent results rather than one-off lucky finds.

Buried City

Buried City is still one of the most dependable maps for rare attachment farming.

Best spots:

• Arto Tower pharmacy breach room
• Plaza Rosa
• Zipline ledge building with residential containers

Why these work:

• Good residential container density
• Fast to hit in a short raid
• Strong history of dropping all four target attachments

If we want a straightforward farming map, Buried City is the safest recommendation.

Spaceport

Spaceport is better than it looks once you stop focusing only on key rooms.

Best spots:

• Container Storage breach room
• South Launch Tower
• North/South Trench Tower stair lockers
• Shipping Warehouse key room (secondary option)

The key point here is that some of the best loot is outside the obvious premium rooms. In practice, Container Storage has been one of the strongest attachment routes on the map.

Dam Battlegrounds

Dam Battlegrounds has some of the most interesting upside.

Best spots:

• Control Tower outer area
• Dam Staff Room key room
• West Hydroponic Dome Complex
• Testing Annex red lockers (lower confidence)

Control Tower is especially good because it can also offer Level 3 weapon upside, which makes the run more rewarding even when the attachment drop doesn't happen.

Here's the quick comparison:

For pure consistency, Buried City and Spaceport are still the best places to start.

Best Farming Routes Right Now

If your goal is efficiency, these are the routes most worth repeating.

Best reliable route

Buried City:

• Arto Tower pharmacy
• Plaza Rosa
• Ledge building

This route is simple, known, and efficient.

Best route for experienced players

Spaceport:

• Container Storage
• South Launch Tower
• Trench Tower roof entry into stair lockers

This route rewards map knowledge and movement.

Best high-upside route

Dam Battlegrounds:

• Control Tower
• Outer Control Tower containers
• West Hydroponic Dome

This is the route I'd run if I wanted attachment chances plus the possibility of premium weapon loot.

Day Raids, Night Raids, and Scrappy

There's still no solid evidence that night raids or storm conditions improve attachment drop rates. They might, but right now that's still theory, not proof. Day raids already produce enough successful drops that they remain the best baseline for testing and farming.

As for Scrappy, there does seem to be a small chance to get these attachments there too, but it's extremely low. The best reported option so far is Agave. I wouldn't build a farming strategy around it, but it's worth knowing.

FAQ

Where is the best place to find Kinetic Converter in ARC Raiders?

The best current options are Arto Tower pharmacy and Plaza Rosa in Buried City, with Container Storage in Spaceport close behind.

Is Silencer 3 the rarest attachment?

From current farming results, yes. It appears noticeably rarer than Kinetic Converter, Horizontal Grip, and Anvil Splitter.

Do I need key rooms to get these attachments?

No. Some of the best reported drops come from breach rooms, residential containers, and side-route loot spots, not just locked rooms.

Are day raids good enough for farming?

Yes. Day raids are already producing rare attachments consistently enough to make them worth running.

Final Thoughts

If we want the best balance of consistency, speed, and realistic results, we should start with Buried City, then move to Spaceport once we're comfortable with tighter route execution. Dam Battlegrounds is excellent when we want more upside per run, especially around Control Tower.

The biggest mistake is overcommitting to special rooms and ignoring efficient container routes. In ARC Raiders, rare attachment farming is less about one lucky chest and more about running the right path often enough to let probability finally work in our favor.
