MG3 shell (body)

[rogue_artist]

Hello,

I am trying to get MG3 parts for a display. I just want the body, an empty shell. Can anyone help me out with dealers, surplus or the like?

I had heard some company made a shell for a Ruger .22 or some such. Plastic body that fit over a Ruger targeter, I guess. Anyone seen these? Are they a good approximation?

Thanks for any help!
