The timing IS adjustable, but the timing is adjusted with the length of the on/off pin.
by changing the length of the on/off pin you're changing the relation beteween when the air valve recharges and the sear catches the valve.
now... DON'T SCREW WITH IT. It's set at the factory, and if you have issues, talk to an AGD tech at a tourny... or talk to me. :-)
I've never seen a mag NEED timing. they are timed conservatively, so it's never an issue.
