I have a precision AR15 already and a 6mm creedmoor bolt gun ordered that are set up for PRS. In order to use them in F class, my research indicates that I will need to take the brakes off and stick a half round length of cut pvc pipe in my mags so I can single feed. Additionally, I might want to transfer my Sightron SIII 10-50x60 from my FT air rifle and use that at max power. In north texas, the closest matches are in east Texas and they max out at 600 yards, so I don’t need to avoid using Sierra match kings for my AR15. Does that basically cover it? Is there anything else I need to do?
