Comparing the Bergara B-14R Trainer to the BMR in 22LR, is the HMR stock on the trainer model the main factor in the price difference? The specs are quite similar, +/-2 inches, +/-3 lbs, and stock appearance are the the main differences I see. Ultimate Reloader did a video featuring the two side by side but all I see is one rifle geared toward the Rem 700 platform and one towards lighter weight or hunting. Are you basically paying extra to get the Rem 700 platform or is there more I am not seeing?
