I have 4 of these Magma moulds. I've never used them but they have been used. They look completely serviceable to me. They are keyed for Magma or Ballisti-Cast machines. I can set them up with either a Magma or Ballisti-Cast sprue plates. $50.00 each shipped.
Such a deal! Nobody has posted on this thread so I sent you a PM. Id like one mold if they're not gone. Oh, and if they are sold it'd be great to know, eh?
