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.
