Some dis-assembly is needed to remove the breach bolt. Not hard to do, but pay attention.
The lever and locking bolts have to come out, which means the ejector gets released.
If you use a slave pin and dummy cartridge to hold the ejector in place, it is easier to re-assemble.
While the breach bolt is out, I recommend replacing the ejector spring. Doing so smoothed out cycling on my Rossi 92.
