If you removed the bolt, you probably lost the ejector spring. A new one can be had from Numrich Gun Parts. To replace the ejector spring, remove the bolt, and take out the spring from the bottom of the receiver just behind the ejector port.
gunpartscorp.com has them listed for $1.70
Put a drop of lubricant on it then use a spent casing to push the ejector in and out to get the lubricant to the spring.

Got an answer from the importers. The Ejectors are held in place by the Ejector Trips, these run vertically up and into a slot on the ejectors. On the ejector trip is a very small pip with a hole in it, underneath this hole there is a small plunger and coil spring (this keeps the ejector trip in place, not allowing the ejector trip to drop down). To remove the ejector you need to have a small pin punch that you place into the hole of the pip. The process of removing the ejector is as follows, keeping the ejector held into the barrel, insert pin punch into pip hole (depressing the plunger and coil spring), pull the ejector trip very slightly downwards. Releasing the ejector it should now slide out. When replacing the ejector all you need to do is push ejector back into barrel and at the same time push ejector trip upwards locking ejector and ejector trip in place.
There is a hidden groove on the bottom of the ejector spring area. While initially it seems as though you should mount the spring with the half moon facing up to match the cutout in the gun you actually put the half moon piece down in the groove on the bottom which holds the spring in place and allows it to sit flush inside the gun save the ejector portion on the end.
I have a crackshot 22 and I might be able to get a ejector made by a friend at work . if you would like me to ask him , let me know.meanwhile, DO NOT FIRE that rifle...a word of advice from a dummy,that did fire a gun without the ejector. it almost cost a trigger finger.
Wisners list it but dont answer e-mails
Yes, but ejector spring may need modification- slight change in slot for spring.
The ejector located inside the left side of the receiver is drug reward by a leaf spring on the bolt on this rifle. The ejector has a shoe on the forward end which is part of the chamber and assists the extractor in removing the cartridge from the chamber. About halfway to the open position a coil spring located in a slot on the left side of the receiver under the thin metal cover overcomes the bolt spring pressure and pops the ejector loose and returns it to its forward home position. As the bolt continues rearward a lip on the back end of the ejector contacts the cartridge case rim and kicks it out when the bolt is fully rearward.
