But a Bren gun was designed to be a crew-served light squad automatic, fired from a bipod or tripod or a vehicle or anti-aircraft mount.

A budding Rambo or Terminator might pick one up and fire it from the hip or shoulder, but they're not going to hit anything with it outside of a movie.

Now if you set up your rat-killing Bren gun in a dug-in hidden offensive position near the rat run, and you and your loader are very quiet and wait until you can see his beady eyes, then unload half a magazine of .303 at him, you might get some positive results.

There might be some "Lucy, you got some 'splainin' to do" with the local gendarmerie after, but the rat won't be involved!
