For those of you here who follow britishmuzzleloading forum on Youtube, Rob Enfield is a familiar figure. In this movie part, 1 of 2, he visits the UK and the Vickers Machine Gun Association, and gets to shoot a couple of full-auto Vickers MGs and two versions of the BREN light machine gun, said to be one of the very best of its kind ever produced.

I'll try and field any questions you might have about the events - just remember than here in UK there is NO NFA class 3 licensing like you have - Rob was in a VERY privileged position in the making of this movie. Serious question only, please.
