This works great
This is a great edition to a Mec Jr Mark V...but it does take a little diddling with to make it work consistently. Nothing major but if you're not a little mechanically inclined and not familiar with the Mec Jr operating functions, you might be a little frustrate. It took me about 20 minutes to get this working flawlessly. Biggest issue was the plastic cover on the feed tray had to be trimmed to get the proper angle on the feed tray to ensure primers dropped every time.
