Hello forum,  I have recently purchased this Colt demilled BMR receiver from an auction.  Its darn rusty on the inside and pretty pitted, as you can see from the close up of the markings.  The charging handle more or less holds the rear end on.  My question to the forum is what to do about the rust.  I have soaked it in WD40 and cleaned that off with contact cleaner then covered it in gun oil.  I'm not sure that will keep it from rusting further.  I want to try and preserve it as best I can but I'm afraid the rust will just keep advancing.  

So I would think my choices would be to keep it oiled as is or go the other extreme and clean it with some sort of rust cleaning solution and have it reblued for protection.  I know to some that is sacrilege and should be left alone.  BUT it is rusting and needs protection.  When I received it, it looks like something was done to the outside as the pits are clean but the inside was left alone.  At the moment I'm leaning toward do nothing to it, just keep it oiled.  Any thoughts?  Thanks.

 

Why bother with this?  Because i'm a history nerd and enjoy these these things.  I want it protected and not forgotten.

Soak it in non-synthetic transmission fluid. WD-40 won't so the trick.

I have done a lot of research on cleaning but not sure if I should attempt a restore like a reblue or leave it as is.

IMO don't refinish it. Its value is as a relic. Making it all shiny and new sort of defeats that.

Hi Ssjtristan, try this. Coat with Fluid Film, wipe down, repeat every few months. Fluid Film will eventually season the metal and preserve it as it is. It will be sticky when wet and takes a long time to dry, but nearly invisible when dry.

Thanks for the feedback everyone. I will keep it as a relic. I was afraid to do anything permanent to it.
I had to look into the rust converter stuff that was mentioned. Never knew that existed! Looking into the fluid film as well. Thanks again.
