Does anybody have any information regarding the wire diameter for the various weights of firing pin springs for the ARC Nucleus actions? Not having any problems, just wanting to know what I have in mine.
Emailed American Rifle Company two weeks ago...no reply. Called and did not get a live person so I left a message last week...crickets.

I can look tonight.
When did you get your action?
After about March of last year everything had 25#
 
I’m pretty sure the color of the spring denotes the weight.

No color, no stripes, that's why I am asking about wire diameter.
Both actions are Gen 1, both came from PVA during that cluster#&@K!
 
I can measure mine. I have a lightweight, mid weight and heavy springs.

The lightweight is 16 pounds
The mid weight is 19 I believe
The heavy is 25

The 16 pound is in my gun so I won’t be able to measure it but can measure the others if you want.

I would greatly appreciate it sir.
 

Surprisingly accurate if you take good measurements. Make sure your units cancel.
