The term length of pull refers to the distance between the face of the trigger and the base of the stock against the shooter’s shoulder. Length of pull is an important consideration in fitting a long gun (rifle or shotgun) to the shooter and can vary based on a person’s size or the type of clothing they wear. Most traditional rifles and shotguns have a fixed length of pull, so it is crucial that a potential buyer holds the firearm in representative clothing for the situation to make sure it can be held securely and aimed properly. Most modern sporting rifles like AR-15s feature an adjustable stock that allows them to be customized for a wide range of shooter sizes to dial in the length of pull.
