A typical break-action, double-barreled shotgun. A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm.Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the ...
