Neilsen Firing Pin Spring Replacement

[Blindbat]

OK.....so I'm getting through my list of lock-down projects. Next on the list is to replace the firing pin spring on my Nielsen nm600. I have visions of small bits and pieces flying into the air never to be seen again without detailed instructions so all help will be gratefully received.

Is it an OMARK firing pin spring ? (my NM 300 is)

[Blindbat]

Yep. It's an omark spring. I understand they are the same.
