This is a double stacked 40 round mag for slug darts. Changes: The V1.0 was too long. More simple, but is now tall. As of now, this is still a work in progress and has not been tested. It is designed to work with DvZ Hybrid pusher, and It needs this pusher. The V1.1 is for flywheels only (V2.0 will be for Springers, and V3.0 will be for Both). Unlike the Worker double stacked 40 round mag, this is designed for slugs and can fit in most mag-wells. Instructions on how to assemble it are similar to The Vorpal Mag Kit by Coatduck.
