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.
