Parallax issues were pretty commonly reported. I had one with that issue and another one that was fine.Found this thread because I have an 6-24 AMG-5 that needs to go back to Vortex for service and wanted to see if there were any similar issues with other owners.
Purchased it in 2020 and it has spent most it’s life on either a 6mm AR or a 22lr bolt rifle. Recently will not focus parallax on any object greater than 300 yards away.
