Recoil calibration paks are offered to allow the shooter a choice of recoil springs to calibrate the recoil function when the correct spring rating is not known. These paks offer a savings of 20% over the same purchase of individual springs. The shooter starts with the strongest spring in the pak and works down until the desired recoil function is obtained.
