1st things first, this does not lock up super tight like a MDT or XLR adapter. There is some play in it. You could drill and tap some tensioning set screws, like a XLR, or put it on something that doesn't need a granite-like lock up. The free play isn't horrible, but I like full disclosure. I'm selling it for $70 shipped in the US only, PayPal or money orders are GTG.
