The hot metal carbonizes the surface as the oil contacting it "burns" in zero oxygen, (a bit similar to charcoaling wood) but with lots of carbon.
Could you do an entire barrelled action?
Dubious, forĀ  few reasons.
!: Getting all of it evenly & deeply heated. We're talking heat (calories) here, not temperature (degrees). It would need some kind of furnace.
2: Getting it transferred while hot. Even tongs grasping it briefly will heat sink. That will show up as a different color when done.
3: Getting it evenly into the oil so both the metal & the oil is always at the exact same even temperature to begin with.
4: Getting it ALL into the oil all at the same time, you're probably be best dropping it free fall!
5: Its going to be incredibly smoky, smelly & messy! You'd have to use some kind of cast iron pipe for the oil, & big enough to take the barrelled action. That means several gallons of oil!
6: Its going to boil even if briefly, possibly burst into flames even.
7: You're going to need a second (sheet metal galvanized gutter drain pipe, duct-work with an end cap, or something) oxygen restrictor to drop over it all fast & safely to stifle the (large, spectacular) fire.

I think it might be a really good re-enactment of a volcanic eruption!
Confused










Have you seen the 'Forged in Fire' TV series ?

Some spectacular 'oil fires' when hardening the blades.

If I did that the rifle would be named "Vesuvius"! Evil Smile

We used to oil blacken some of our work in Metalwork class at school; back in the day's when you actually got dangerous stuff at school. There where frequent fires in the oil tray. We had a hinged lid that opened to the rear of the tray. Not the easiest thing to close when the tray is in flames! When you have snuffed it out the amount of smoke when you reopen the lid is substantial!
It's nice to be important, but it's more important to be nice!
