Ah the Owen (You get one as a player in "Bushpigs") Sighting??? Carl? Australians sighting a submachine gun??
Seriously though, they were designed to be fired from the hip and like most sub-machine guns, accuracy didn't suffer for it.
Additionally,due to the top mounted magazine, fixed sights were offset to the left.
One advantage to having the magazine on top was it allowed you to lay on the ground and fire from a lower profile. The Sten had this advantage though without drawing attention to your position with the magazine towering over your position
Although quite large and bulky, the Owen was a first-class gun and very popular with those who used it.It stood up well to the hard conditions of jungle fighting and stoppages were remarkably rare. Its two outstanding features were the top mounted magazine -- a feature rarely seen on submachine-guns since the Villar Perosa -- and the provision of a separate bolt compartment inside the receiver so that the bolt was isolated from its retracting handle by a small bulkhead, through which passed the small diameter bolt. This ensured that dirt and mud did not jam the bolt and it was highly successful, although expensive in terms of space.
Two other unusual mechanical features: the ejector is built into the magazine rather than into the gun body, and the barrel is rapidly removable by pulling up on a spring-loaded plunger just ahead of the magazine housing.

Mk 02
It's an ugly weapon but quite a good one. Reliable as hell.
