a gunstock is broadly divided into two parts (see above). the rear portion is the butt (1) and front portion is the fore-end (2). the fore-end supports and affixes the receiver, and relays the recoil impulse from the barrel. the butt interacts with the shooter's trigger hand while being braced against the shoulder for stability, and is further divided into the comb (3), heel (4), toe (5), and grip (6). the stock pictured has a thumbhole (7) style grip, which allows a more ergonomic vertical hold for the user's hand.
