Sentinel Firing Cores come from destroyed Sentinel ARC machines. ARC Couriers are also listed as a source, so a nearby Courier is a second option. The best-known search areas are on Dam Battlegrounds, but none of the listed spots is guaranteed to produce a core in every match.
Where Sentinel Firing Cores come from
The ARC Raiders Wiki’s item page for the Sentinel Firing Core lists two sources:
- Destroyed Sentinels. Defeating a Sentinel ARC machine is the primary route. See the Sentinel Firing Core entry on the ARC Raiders Wiki for the item’s listed sources.
- ARC Couriers. The same item listing names Couriers as a source. If one is close to your route, searching it is a practical alternative to hunting a Sentinel.
Sentinels
Sentinels are the more reliable-sounding of the two options on paper, but the wiki presents their locations as broad map areas, not fixed spawn points. The next section covers those areas.
ARC Couriers
PC Gamer’s guide suggests checking Couriers around Research & Development on Dam Battlegrounds while you are already in that area. The guide does not describe how often a Courier carries a core, so treat a Courier search as an opportunistic stop rather than a dependable farm.

The guide notes that Sentinels are not guaranteed to appear at these spots in every round. Use them as the places most worth checking, not as a timer-based respawn point.
When Sentinels are most likely to appear
According to the Sentinel page on the ARC Raiders Wiki, Sentinels are most commonly found during Hurricane map conditions and in areas with large vantage points. If a Hurricane is active on a map you are running, the Sentinel areas above are the places to prioritise.

What to do after a Sentinel goes down
- Search the wreckage where the Sentinel was destroyed.
- Check the ground below the Sentinel’s position. The PC Gamer guide reports that the chassis can fall to the ground below, so a core may not be where the machine was standing.
- If you are on Dam Battlegrounds, finish the check at the nearby Research & Development staircase or the destroyed dam, since those are the listed search areas in that region.
How many cores you need and what recycling returns
The ARC Raiders Wiki item listing gives the following values:
| Use | Cores required or consumed | Result |
|---|---|---|
| Gunsmith upgrade from level 2 to level 3 | 4 cores | Upgrade requirement, as listed on the wiki |
| Recycling one core | 1 core | 2 ARC Alloy and 2 Mechanical Components, as listed on the wiki |
The wiki’s figures do not state the year the underlying game data was published, so check the in-game Gunsmith screen before spending cores if the requirement matters to your plans.

What the sources do not establish
- No drop percentage for Sentinel Firing Cores from Sentinels or Couriers is published in the sources reviewed.
- No guaranteed number of Sentinel kills, Courier searches, or cores per match is established.
- Spawn locations are described as broad areas, so a Sentinel may be absent from any listed spot in a given match.
Because no drop rates are published, the sensible approach is to search every Sentinel you destroy and any Courier that is on your route, rather than planning a route around a fixed expected yield.
