Need help stripping ACR lower receiver

Trying to strip my ACR receiver so I can duracoat it but running into problems. Can't figure out how to get the retaining pins out, or how to take apart the magazine release assembly.

The mag release seems the most complicated, it has a release on both sides, as well as by the trigger well that requires to be pushed up.

I added pics, I'm sure this is easy I'm just having a brain fart.
