A short update. (If anyone is still here or paying attention smile )
I made the new front sight this week and it is of sufficient height to compensate for the issues I was seeing plus a little more so I can regulate it at the range with a manual milling machine (ie; what my friend Ric calls a File). New testing won't happen for a few weeks at best as the snow is deep and winter is long. I'll report again when the seasonal climate change occurs and the snow melts.
