Er, the Maruzen APS2 L96 is pretty much the best documented airsoft rifle as far as upgrades go. To my knowledge, the only possible difference between the AGM and any other clone is the cylinder internals.
The AGM l96 is takes very different parts Proffrink, They use VSR triggers but the cylinders are thinner than VSR, they are the same width as the APS cylinders. They take VSR springs and spring guides BUT the piston, albeit VSR shaped, is not VSR sized, the width is smaller to fit in the cylinder.
