History / Summary

The X3 F1 was designed by the Australian Ordnance Department and combines the features of the Owen with those of the British Sterling sub-machine guns. The bayonet, pistol grip and butt plate come from the L1A1 rifle to simplify production. The bolt is a modified Owen design giving good protection against dirt and the top-feed magazine feed of the Owen was also carried over. This X3 is a prototype of the production F1 sub-machine gun.
