The front lug........ Just before the last of the old L4A4's went out of service I was on the range with a load of 5RGJ(?) soldiers just out of their recruit stage. There was feed troubles with one particular Bren that their resident NRPS Armourer couldn't fathom out. So I went over to it and saw that the magazines wouldn't retain in the gun as the breech block went forwards. The magazines would disengage FROM THE FRONT!!

I couldn't see what the problem was until I looked at one of the loaded mags that had been taken/lifted out of the gun and saw that it was a FN type front lug. Not only that, the whole mag box were that sort, presumably unused and in a store rack since the L4A1 era. So there was some quick unloading of duff mags and loading of service mags before they could carry on.

I don't know what happened to them but it shows what happens when you get a mixed fleet. When I wanted a couple of 30 round FN type several years later for an L4A1 gun at Warminster I couldn't find ONE!
