I need to do this. On my work trip, I booked my return flight from Huntsville a day late so I could take a day off and enjoy the range. I flew with a 1903A4 that I de-sporterized. It had an original A4 receiver. I used a NOS GI barrel and a NOS field replacement scant. It came with an original GI Redfield base, so I only had to find the split top rings, which took some waiting. I used a Hi-Lux replica scope, which did the job just fine. I shot off the bench to minimize the gear I had to fly with. I was getting solid groups in the 10 ring at 600, sans the wind flyers as the wind is normally very strong and very shifty on that range. By late morning, every flag was standing straight out, but all were in different directions. I was lucky to get a few shots off before it shifted, then making a new call it would shift to the complete opposite before you could get the sight settled on target.
