Can anyone help me ID these 2 weapons systems please?......

Probably the wrong place to post, but as this long time established member now has the great indignity of having to wait to be authorised it seems, what choice do I have?

I'd really like some help ID'ing these 2 weapons systems from a Pave Low that I photographed yesterday. Both images are focus stacked from about 14 separate images, so the hi-res images are full of detail

Top one looks like a 7.62 mini-gun, bottom is a Browning M2 .50 cal.
