M1 carbine

[G.I.]

How do you take the carbine bolt apart to check the codes?

 

[Dfariswheel]

You don't.
The manufacturers code is plainly stamped on one of the bolt lugs, right where you can see it.
This will usually be a small one or two letter stamp.
The firing pin code is stamped on the exposed rear of the pin.
The extractor code is on the extractor lug where you can see it.
Some firing pins and extractors may not have code stamps.

If it's ever necessary to disassemble the Carbine bolt, you'll need a GI type bolt disassembly tool.
WARNING: The Carbine bolt looks like a miniature M1 Rifle bolt, but it does NOT come apart the same way.
Try to just push out the extractor like you do on an M1 rifle and you'll ruin the Carbine extractor.

Thanks for the info on the carbine bolt, I was worried I needed to take it apart.

It might be a good idea to have a carbine bolt tool around anyway in case you ever break an extractor, or have an ejector spring go limp, etc. Old, old parts, you know. And the tool for removing the trigger spring. Maybe a gas piston wrench too. I got all that stuff from the old days of the 150$ Koreans. I wish I had visualised the investment prospects for all the nice collector grade carbines I sold off relatively cheap.
