Barrel Length (BBL)
"The length of a barrel as measured from the muzzle to the standing breech in a break-open gun or to the bolt face in a bolt-action rifle, including the chamber. A revolver barrel measurement does not include the cylinder, only the barrel itself. "
The condition of a firearms breechblock in firing position.
"A round sight normally used at the muzzle of a shotgun or the front sight of some rifles, in which the sight is viewed as a round bead on a narrow post. "

"Generally, the front sight of a rifle or handgun, seen by the shooter as a post. "

"A breechblock, generally circular in cross-section, that moves backward and forward to open or close the action. "
Bolt action is a type of firearm action in which the gun's bolt is operated manually by the opening and closing of the breech (barrel) with a small handle, most commonly placed on the right-hand side of the gun (for right-handed users). As the handle is operated, the bolt is unlocked, the breech is opened, the spent shell casing is extracted and ejected, the firing pin is cocked (this occurs either on the opening or closing of the bolt, depending on design), and finally a new round/shell (if available) is placed into the breech and the bolt closed. Bolt action firearms are most often rifles, but there are some bolt-action shotguns and a few handguns as well.
