I guess I posted the same issue in the wrong area. I was wondering if an air gunner can shoot 100 yards with standard two piece rings, or does he need adjustable rings to get a .22 caliber pcp rifle out that far? I'm try ing to set up a gun, and have zero experience with air gunning that far. Don't want to buy more than I need, or buy twice. I will definitely need two piece mounts to clear the magazine. Thanks for the help.
