What does the forestock of a bolt-action rifle allow for?

The forestock of a bolt-action rifle is designed to provide support when aiming with the non-trigger hand. This part of the rifle allows a shooter to stabilize the firearm effectively, helping maintain accuracy, particularly during longer shots or in situations where a steady aim is crucial. By gripping the forestock, the shooter can guide the rifle more precisely and reduce the effects of movement and shake, enabling better control over the shot.

In contrast, other options do not accurately describe the primary function of the forestock. For instance, while the rifle may have other parts or accessories for storing magazines or accessing the trigger, these functions are not associated with the forestock. Additionally, the sealing of the chamber during firing is related to other components of the firearm that ensure safety and proper functioning, rather than the forestock itself.
