Breechblock Handle

A breechblock handle is a component of a firearm, specifically a bolt-action rifle or a breech-loading shotgun. It is a lever or a knob that is used to manually operate the breechblock, which is the part of the firearm that seals the chamber and holds the cartridge in place.

The breechblock handle is typically located on the side or the rear of the firearm, and it is used to open and close the breech. When the handle is pulled back or rotated, it unlocks the breechblock, allowing it to move rearward and eject the spent cartridge case. When the handle is pushed forward or rotated back into position, it locks the breechblock, securing a new cartridge in the chamber.

The design and location of the breechblock handle can vary depending on the specific firearm model. Some handles may be a simple lever, while others may be a more ergonomic knob or grip. The handle is an essential part of the firearm's operation, providing the user with a means to manually control the loading and unloading process.
