I love the Bren for it's rifle like ability to shoot on semi-auto and still gives you survivability in close quarters, but I hate the sights. Like on of the previous posters, I lose track of targets completely. But I have the same thing with the cirkel-sight of the No.4 rifles, and the Lewis sight is just a round hole as well.
Is there some British design aspect to it, to have such a thick and round ironsight? I mean, IRL, does it make aiming easier or something? Or is it a design flaw?
