Well the taller front sight has arrived. I had to use some 800grit wet and dry to take a bit off the base of the sight post to get it to fit but it is still taller than the previous post. This also tied in with another NECG aperture sight for the CZ550 arriving from NECG. Note. I was told on the phone by one of their employees that they do not export to Aussie. I explained that I had been told they would by email and they did. Go figure.

Now to find some time to get to the range and see where my shots are going now.
Cheers
Greg
