I have 2 questions, does an Automag RT/Pro have the same barrel threads as a autococker or any other gun?

I am having a problem finding barrel adapters for mags and another thing is i have good barrels for autocockers and spyders, one being a boomstick and a ultralight, I was reading some posts and a few people said that some mags have autococker threads, is this true on a Automag RT/Pro?
