Forgive the simple question but my google searching failed me. I want to double check headspace on an Origin shouldered prefit. Is removing the firing pin enough or should I remove the extractor and ejector prior to checking headspace?
 
slide the gauge up the magazine well behind the extractor. do not cam the extractor over the gauge like single feeding a case

ejector is mechanical and in the rear so nbd

do you have issues chambering brass?

No known issues yet. Just finished the install and figured I'd check it just to be safe.
 
If it’s a shouldered prefit barrel from a good smith, you should be golden but nothing wrong with double checking.
Should be golden, but gunsmiths are humans and people make mistakes, no matter how good they are. It could be as simple as an engraving mixup with the wrong caliber or a shipping screw up. I'd strongly encourage anybody to double check headspacing the first time a shouldered PreFit is screwed on an action, even if it's just with the brass and tape method.
