You never came back to me with what you wanted for your bits. I see that you have now added them, but I would recommend you put them in the 'for sale' section as more people will see it. I have just bought a TX200 today and need a scope and a stock now. I can't see any info from Bushnell about the 4200 tube size. I don't think though that it is 30mm, which is what I am really after. Is it 25mm?
