Rainmaker apart for service, what else should be done?

[CSM_Paintball]

Finally took this thing apart after sitting for decades as I plan on getting it in running order. Aside from o-ring replacement and lubrication, is there anything else that you guys recommend I do while apart? Thanks!

Look up the Mad Marty Mods that were designed to stop the RM from shooting itself apart.

I'd recommend a new mainspring, checking carrier spacing, and gutting the regs and replacing them with aftermarket ones as well.

Feedneck mod to empire spec, so you can actually clamp on a hopper instead of using a screw.

I ended up drilling a hole in my revy to “lock” it in place because of that
