Building Power Armour troopers part 2

Look here for part 1

I wanted to equip my power armour troopers with a close-in weapon system to shoot down incoming missiles. Rummaging around in my bits box, I found some 1:48 rotary machine guns.

Together with a piece of guitar string and a chopped up Tau 40K flamer I turned this into a magnetized close-in weapon system.

This is how the power armour trooper looks with the different configurations after priming:

Close combat configuration with a right and not-left left close combat arm:

Heavy configuration with a main weapon arm, not-left left close combat arm and close-in weapon system on the shoulder harness (one of the hard points on the shoulder harness is a permanently fixed missile pod).

Another heavy configuration with a regular left arm and smoke/flare/grenade launcher instead of the minigun.

And per request a comparison snapshot together with a crooked-dice ghostbusters figure:
