mossberg 500 old rocker vs new style bolt?

[hotshot89]

Ok so I picked a new haven 600at same as mossberg 500 for cheap. I'm having issues with ejecting and extracting. Not everytime but maybe 6 out of 10. Its a older gun with the sn starting with a H and has the old rocker style bolt. So my question is will extractors for the new style bolt fit my rocker style or must I find extractors for the old bolt???? any info is greatly appreciated and info on whether other parts from the old vs new style will interchange .. shell elevator ect... thank you

Not sure on the bolt question...
But, the Mossberg has the ejector screwed onto the left side of the receiver. On my older Mossberg, I started having some failures to eject, after many years of faultless shooting.
I found that the ejector screw had backed out a couple turns.
Tightened it back down, and used locktite.
Seems to have fixed it...last range trip, no issues.
BTW, there is a Mossberg forum...very helpful guys there.
