A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge.

A linstock (also called a lintstock) is a staff with a fork at one end to hold a lighted slow match. The name was adapted from the Dutch lontstok, "match stick". Linstocks were used for discharging cannons in the early days of artillery; the linstock allowed the gunner to stand further from the cannon as it was dangerous applying the lighted match to the touch hole at the breech of the gun. Not only could the charge flash back, but the recoil of the cannon might send the carriage toward the gunner.
