Numrich Bolt head question

[boostless]

I think I'm gonna order a bolt head from Numrich, it says it doesn't include the ejector and spring with it. I'm I right to assume it also does not come with the extractor?

Either case it may be will I be able to take said stuff from my old bolt head (223 SA) and put it on the new head (308 SA)?

It will not include the extractor, and your 223 parts will go right into your new bolt head.

Unless they've changed the extractors for the .378" boltheads (223-204) are longer from the ball detent to the outside edge. When used in the .473" bolthead they'll jam against the lug recess when it jumps the rim of a .473" cartridge. You'll need a new extractor or shorten the one for the 223.

Thank dog06 for this pic showing the difference.
