I have a customer in California with a Black Chrome plated M94 receiver. According to the Dulite website the base metal is a cast graphitic steel. This will not blue with standard chemicals including rust blueing. Dulite has a system using a product called Dulite 3-0 to blue these receivers once the chrome plate is removed.

Are there any shops out there set up to do this work? Contact info?

Thanks,

Yes, they are made from what drills and machines like iron. Check with Craftguard in Waterloo IA.

It's cast graphitic IRON, not steel .There is a graphitic steel which is a tool steel, a very different sort of thing.

craftguard at one time said they could re-iron those action, another way is strip and satin chrome but then have realign barrel

I'm not a big fan of coatings on guns but in this case I think cerakote would be a good choice. Whether your post '64 receiver is made of sintered metal, graphitic steel/iron or some other bastardized metal, cerakote should work just fine.

It would save you from messing around with re-plating or buying special bluing salts that have to be set up a separate tanks. Has anyone ever tried to melonite/black nitride one of these port '64 receivers?

These guys just did a really nice job bluing a stainless receiver for me:

No idea whether their process will work on your Winchester but it would be worth asking.

I called Craftguard; they can't blue them. Of course, and of the paint coatings like Cerakote, etc, will work. I have just polished them bright and they don't look bad that way.

Thanks for all of the suggestions. I'll follow up on them.
