I like the acetone/ATF idea. Make up a good sealable jar full and put the entire receiver in for a few days and let it do it's stuff. I use wide mouthed Pnut butter jars for that kind of stuff.

Guys just remember if you are using acetone "No open flame" or even possible open flame. Ie do this outside.

Eric, We all live a bit dangerously some of the time. I'm still kicking after all these years, for no good reason! David

Okay... ATF... but that's just a generic term. Is it FLM or is it Dexron II or Dexron III or even one of the later ones? Possibly one of the synthetic ATF's???

[Double Lab]

It does'nt matter Dean, any ATF will do. I use it to free up rusted, greased encrusted screws/bolts and motor bearings. Works better than any commercial product I've ever used.

I have tried these ATF/Acetone concoctions, and find them unsatisfactory for typically dried oil/gummed up gun parts.

While this may be a fun experiment in alchemy, this stuff does NOT work as well as immersing gummed up gun bits in a full bath of lacquer thinner for a few days. Lubrication is okay. But dissolution/breakdown of old goo is really what you are after.

Try leaving in hot sunshine for a few hours. An old remedy.
My two cents!
