The Weihrauch HW100 FSB (Field Sport version with thumbhole stock) combines the regulated HW100 action with an ambidextrous thumbhole beechwood stock that provides a more positive grip angle for field target shooting. The thumbhole grip reduces movement when the trigger is pressed and maintains consistent stock-to-cheek contact between shots during multi-shot string competition.
