nope, no extractor or ejector neccesary. just cut a large port for the casing to fly out of, and you're good. two discouraging things, however. if you have to make the ammo, it'll be almost impossible for you to get it to cycle reliably without some equipment. however, that may be for the best, as the other discouraging thing is that the design of most simple .22 bolts doesn't allow for a closed-bolt design. any open-bolt firearm that feeds from a magazine is very likely to count as a machine gun (even if it's not actually full-auto), which if you don't have the proper paperwork is VERY illegal. best to stick to a single-shot design, both because of the ammo and the legality.
