A mechanical painball marker manufactured by Airgun Designs(AGD).
The Automag, along with the Autococker, were the premiere markers back in the mid 90's. The widespread acceptance of electronic guns resulted in the Mag's decline.
However, due to it's quality and reliability, the Automag still retains a small but loyal following.

My automag is built like a tank...not like that made-in-China Smart Parts garbage.

Automatically, but in a way that, for some reason (typically because it is too complicated, or too ugly, or perhaps even too trivial), the speaker doesn't feel like explaining to you.

This term is quite old, going back at least to the mid-70s in jargon and probably much earlier. The word `automagic' occurred in advertising (for a shirt-ironing gadget) as far back as the late 1940s.
