The Definition of Muzzle Brake
An attachment to or integral part of the barrel that redirects some of the pressurized gas that propelled the bullet out
the muzzle to the sides and possibly rearwards from the direction of the bullet travel. This reduces the recoil of the firearm.

The small lever on a cartridge firearm, which one pulls to cause the spring-loaded firing pin to impact the primer, causing the gun to discharge.
Normally, the trigger simply connects to the sear. Pulling the trigger moves the sear out of its notch, releasing the spring-loaded hammer
to strike the firing pin which in turn strikes the primer; or the coilspring-loaded firing pin directly. Other, often-Germanic systems have their own
miniature lockwork which, when cocked, allows an exceedingly light trigger pull to discharge the firearm, a setting that would be perilous to carry in the field.
Informal shooting at any of a variety of inanimate targets.
An early system of ignition for muzzle-loading firearms where a priming charge is loaded into a flashpan with a separate,
manually-operated cover. To fire, the cover is opened and then a slowly smoldering wick, held in the nose of the curved arm,
is lowered by means of a lever (precursor to a trigger) to ignite a priming charge which then ignites
the main propellant charge inside the barrel.

A firearm is a portable gun (pistol or rifle), being a barreled weapon that launches one or more projectiles often driven by the action of an explosive force.
A family of smokeless propellants developed and produced in the United Kingdom from 1889 to
replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low
explosive because of its slow burning rates and consequently low brisance.
The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target,
but not enough to destroy the barrel of the firearm, or gun.
A type of firearm in which the action is in the open position and the chamber empty prior to firing.
When the trigger is pressed the bolt moves forward, chambering a cartridge and firing it and returning
to the open position. When firing is stopped the bolt remains open and the chamber empty.

A short cylindrical rod of hardened steel running laterally near the front of the bar of a break-open gun's
action around which the barrel hook revolves when the gun is opened. Over the decades, this pin and its
complimentary hook can wear and a gun can sometimes "shoot loose" or "come off the face." The proper cure
for this condition is to replace the hinge pin with a new one, slightly oversized, to compensate for wear
on both itself and on the barrel hook.
