Stargate Atlantis Genii Guns

[Theman10k]

Hi everyone

I'm looking to see if anyone knows if the Genii guns like the 3 barrelled shotguns ever sold off?
The original props and stunt guns?

If so who has them?
What's happened to them?

Also does anyone know who the armourers were for Stargate SG1 and Atlantis?

Cheers
Tom
