The listed recipe needs four cores, alongside three Rusted Gear and five Advanced Mechanical Components. You can recycle or salvage a core, but recycling currently yields more component types.
Where to find Sentinel Firing Cores
The ARC Raiders Wiki item page lists the core’s source paths as ARC → Courier and Sentinel, and describes it as scavenged from destroyed Sentinels. A separate live-index enemy listing identifies the Sentinel as a high-threat sniper turret and lists Dam Battlegrounds, The Spaceport, The Blue Gate, and Buried City as locations where it appears. Treat those map locations as community database guidance, not official developer documentation; exact loot probabilities are not established.
The item page lists a stack size of three and a sell value of 2,000. These are game values that may change with updates.
What the core is used for
Four Sentinel Firing Cores are listed in the Gunsmith 2 → Gunsmith 3 upgrade recipe, together with three Rusted Gear and five Advanced Mechanical Components. The Gunsmith upgrade table gives the full materials list. If you are working toward this upgrade, keeping four cores covers the listed requirement.

Recycling vs. salvaging
The item page lists these yields:
| Action | Yield per core |
|---|---|
| Recycle | 2 ARC Alloy and 2 Mechanical Components |
| Salvage | 2 Mechanical Components |
Recycling returns both ARC Alloy and Mechanical Components; salvaging returns Mechanical Components only. The listed recipe does not establish a universally better choice: the practical decision depends on whether you still need the cores for Gunsmith 3 and which materials you need.
Why older recycling figures may differ
The item page’s history says version 1.17.0 changed recycling from 2 ARC Alloy plus 3 Mechanical Components to 2 ARC Alloy plus 2 Mechanical Components. It does not provide a precise patch date, and no official patch-note confirmation is established here. A separate database currently shows different component quantities, so the versioned item-page table is the clearer reference for the yield above.
