Hi all, I have a question which has been puzzling me. There is probably a simple answear. so here go's, on the UC there is the swing down armour which mounts over the bit you poke the bren through, you know what i mean. when this is positioned in the swung over open position it seems to fit perfectly level, how is this?. i know there is a double coil spring washer washer on the hinge pin, but recently on you tube i watched a clip of UC's being used for training, have a look on youtube great vid. They all sit perfectly level when open, does every commander carry a spirit level to check the wedge armour is dead level when open or is there some kind ok mechanical stop.
