Bighorn Origin bolt help

[Catalyst81]

I wasn't paying attention while I was attempting to remove the firing pin on the bolt of my Origin and I rotated the bolt shroud the wrong direction. It now appears to be stuck. I can't get it to budge or rotate back and I'm out of ideas. Any suggestions on how I can get it oriented correctly again?

You seem to have decocked the firing pin. You can use the edge of an old desk or something and pull the pin back while turning the shroud to reset it.

That's what I was thinking but it won't budge.

550 cord or shoelaces help..

here's a video showing the shoelace method:

I usually just put my bolt in a padded vise and then use a small block of wood to push back against the pin and rotate it back into position. the wood keeps anything from getting scratched and it saves my fingers.

Which direction are you trying to move it? The spring is pretty strong and it will take some force to compress it enough to move the firing pin rearward.

Here is a quick video to give you an idea of what Im trying to explain.

I need to pull it back and rotate it clockwise. I get what you're saying. The issue I'm having is where I'm trying to pull it back with the shoelace is more at a 45 degree angle than a 90 and so it keeps slipping off. May just take it over to my gunsmith.

Push the sear against a wooden surface and turn. Like in this video

No need for a gunsmith in this case

Start by putting some pressure on that sear 'til you can feel the sear/pin go back, it'll be real stiff but springy. Do that a few times to get a feel, then turn the shroud or bolt body, whichever is easier.

It is MUCH easier to simply clamp the cocking piece in a bench vise and then pull the bolt forward and turn it.

i'm so embarrassed to say that didn't occur to me. makes so much sense.

I had to do it today on an ARC Nucleus because the shroud is misshapen and a typical 700 removal tool will not fit.

Using the correct terminology is important.
You probably mean the cocking piece because the sear is inside the trigger module.

Just grab the shroud or plug or whatever that manufacturer calls in your right hand (assuming you are right handed!),the bolt body in your left, it and give it a quarter turn clockwise. It will cam into cocked position just like when you open the bolt while it is in the rifle. I suppose you could use a shoelace or vise if you are worried about your manicure.

They don't make hands like they used to.
These new models are much softer.
