I bought a Blackhawk extended picatinny base for my son's Savage Model 10 .308. It says it's for a Savage Model 10 (Accutrigger). His rifle didn't have the accutrigger, does anyone know if it will fit? Can't seem to find any info on this. Of course I know I can just try it but this is for a Christmas present and with youth deer season this weekend I'm not going to pull his scope and mounts off to try it.
