same as a regular mag, except a spring stops the bolt from setting all the way. when you pump it, you press on the bolt and compress the spring so the sear grabs the bolt.

You need specific items

You need a milled rail and a body that has the larger opening with a ramped slot as well as the Automag Pump Kit.

These are discontinued and Airgun Designs no longer carries them.

Go to the tech forum on Automags.Org to get the diagrams and measurements.
