Gunsmithing Nucleus bolt disassembly help?

Here's a schematic of the Nuke bolt, I got this here on SH and I think it comes from ARC

Also, your Nuke came with a washer to disassemble and reassemble the bolt, but the spring compression tool from ARC (or a homemade alternative) makes it a lot easier.

Nope the wrench for it.

I am having light firing pin strikes. I should have just sent it back to ARC to fix it. But I needed it for a hunt. They sent me a 24 pound spring free of charge.
There is no wrench for it.
ring under it is machined to lock it in place by the firing spring pushing into the castle nut.
Use the big washer that came with action to push lock ring down and it releases the castle nut and it screws off easily.

All the tools to disassemble the come with the action.
Little bolt and washer to retract striker and the big washer mentioned above.

Make or buy one of these to make it really easy.
This replaces the big washer.

I ended up getting it went out and bought a new washer and drilled it out so it fit very tight and used a 1911 armorer block I made a while back to hold it and had my wife unscrew it while I kept the castle washer pushed down.
