You can just use a socket instead but I don't remember the size right now maybe someone else does. Also if you just want one to complete your model 52 accessories they show up occasionally on gunbroker.
By all means get one to complete your "package", but DON'T use it! It will scratch up the end of the barrel/bushing/nut.
I use my fingernail, or the tip of a .223 round, or a small brass punch to hold the pin down for bushing removal. When putting it back on, finger tight is all the factory recommended, so don't over tighten it.
