rusted/stuck firing pin and breech plug

[roverboy]

I got a problem with a firing pin that's stuck and a breech plug too. What would be the best penetrating oil? Store bought or homemade. I may heat the breech plug up with a propane torch and try and get it out that way. I know there's some knowledgeable members on here, so anybody got any advice. Thanks.

I may have to get some. I've heard the stuff is "toadly awesome". Where would I get some without having to order it?

I have had good luck with a 50/40 mix of 30 weight synthetic and automatic transmission fluid. Add 10% fuel injector cleaner to the mix to help it seep. It seems to soak in pretty well but probably not as good a kroil. My mixture works really well if the parts are being heated.

Call your local gunshops, several around here carry it. You could also try machinist supply places.

Most auto parts houses should have it.

I have always been able to find it at NAPA.
