F1

The F1 is an accurate Australian blowback operated, selective fire sub-machine-gun produced around 1960 as a replacement for the earlier Owen, and incorporating components from the L1A1 rifle. The F1 takes a 9 mm Parabellum round from a 34-round curved box mounted over the receiver. It has a cyclic rate of 600-640 rounds-per-minute and an effective range of 200 meters with a muzzle velocity of 366 meters-per-second. The F1 has a 213 mm long barrel and is fitted with a blade foresight offset to the right and a hinged plate aperture rearsight which is also offset.
