Guy's, I am struggling to understand why there is no Boyd Stock in the At-One Thumbhole version for my Savage Model 16, FCSS, DBM, .243 (Same problem with Model 14) Their small print for this rifle say's "Center to Center of Action Screws: 4 7/16" and from what I understand my Model 16 is short action with 3rd generation center to center action screw spacing of 4.400" only 0.0375" or 1mm difference. What am I missing here.

Would a Boyd Model 12 At-One Thumbhole fit instead?

Boyds response:
"I do not show the At One Thumbhole as being available for the 16 Bottom bolt release for some reason must be something that doesn’t work together."

Any suggestions? Thanks.
