Arc Raiders has plenty of annoying materials to track down for various upgrades, like prickly pears, olives, and mushrooms for Scrappy, but I’d argue none are more annoying than Sentinel Firing Cores. You need to grab four of these pesky Arc items before you can upgrade your Gunsmith to level three, which is quite the challenge.

You need to grab four of these pesky Arc items before you can upgrade your Gunsmith to level three, which is quite the challenge.
As obvious as it sounds, it’s worth pointing out that you get these Firing Cores from Arc Sentinels, which are sniper turrets attached to ceilings in just a few specific locations, and are different to the regular turrets you commonly encounter. You’re less likely to run into these naturally compared to almost all other Arc types.
How to get Sentinel Firing Cores in Arc Raiders

The best places to get Sentinel Firing Cores are on the blue exterior staircase at Research & Development and either end of the destroyed dam between Control Tower and Power Generation Complex on Dam Battlegrounds.
I’ve found these to be the most consistent spawn locations for these machines, and you can run between all three areas in a single match, though even these aren’t guaranteed every round. Take note that when you kill these Sentinels, their chassis more often than not fall all the way to the ground below.
You can also find Sentinels on the other maps:
- Buried City: In the yellow bell tower on top of Townhall and inside the Santa Maria Houses courtyard (you’ll come here for the Digging Up Dirt quest).
- Spaceport: In Rocket Assembly, Container Storage, and Control Tower A6.
- Blue Gate: On the concrete area in the northeast of Checkpoint and on the tower in Pilgrim’s Peak. (Image credit: Embark)
Another great way to get Sentinel Firing Cores is actually by **looting **Arc couriers, large, chest-like Arc containers that you can find around all of the maps. These have a chance of containing various parts from different Arc machines, including Sentinels. There are lots of potential courier spawns around Research & Development on Dam Battlegrounds, so my advice is to check these while you’re in the area and hope you get lucky.

Rory has made the fatal error of playing way too many live service games at once, and somehow still finding time for everything in between. Sure, he’s an expert at Destiny 2, Call of Duty, and more, but at what cost? He’s even sunk 1,000 hours into The Elder Scrolls Online over the years. At least he put all those hours spent grinding challenges to good use over the years as a freelancer and guides editor. In his spare time, he’s also an avid video creator, often breaking down the environmental design of his favourite games. If you can’t track him down, he’s probably lost in a cave with a bunch of dwarves shouting “rock and stone” to no end.
