I discovered this handy little tool on a national gun forum. It helps with two difficult tasks when working on a Ruger 10-22. It was kind of weird that I had not seen or heard of this tool before, the creator and manufacturer of the tool is in my home state....
The tool helps with two important tasks on a Ruger 10-22.
One of those tasks is installing the bolt. In order to install a bolt on a 10-22 you must compress the recoil spring (captured on the guide rod/charging handle) and slide the bolt over the top of it while keeping the bolt as far back against the receiver as possible (to clear the guide rail).

This is difficult because the guide rod/spring assembly is not centered in the frame and the charging handle puts leverage on the guide rod making it want to go anywhere but strait back.
The gunsmither bolt bar holds the guide rod/recoil spring in position with one hand making it easy to simply drop the bolt into place
The second feature this tool possess is the ability to hold back the spring on the extractor making it easy to remove the extractor without loosing the spring.
I highly recommend this tool to anyone that owns a 10-22 (which is pretty much everyone who reads this....)
