Description
The GIAT Industries 20 mm F2 (otherwise known as M693) is a dual feed autocannon which fires the standard 20x139 mm munitions. It is a gas operated autocannon that has three firing modes, those being single shot, burst and safe. The gas system of the weapon operates via two vents on either side of the barrel, through which the gases push against the two pistons. While firing, the two pistons are pushed back, moving the struts backwards so that the breech block can move to the rear. In this way, all the firing forces are developed along the barrel centerline which maximizes accuracy.
