I really want to find them on my own but I don't understand how one is supposed to. What is there to go on, no rough maps or clues or anything? That's like finding a Korok circle in Zelda blindfolded..

Gracias for the excellent guide still useful years later. Found all but two circles almost immediately, didn't take more than 2 or 3 minutes to find the others. Despite not have the longest range sight yet, managed to hit all but 2 on the first shot. Was a fun challenge for a quest line, probably my favorite part of the DLC. Really been digging the rifle.

Спасибо.

Thank you, I tried a long time for this and gave up. I then came back to this with your help and finally got it done.

Sorry. This is in regards to #4.

I'm not sure if coordinates differ between using metric or imperial. I used imperial and coordinates are: 7135, 7470 from center of circle. Target is SE.

#10 glitched for me. It was down by default.
You can still hit it when it’s sideways, just a harder shot is all. It will flip “up” into the bridge after so shoot it again to knock it down so you don’t launch your ATV off the bridge like I did.

Supreme guide, even logged in to give a thumbs up

i hit all 15 says mission complete. Although it does say something about challenge targets no idea. But the point is the gun did not unlock for me.

@Slysi I'm happy that my guide helped you
