19 Other Firearms Definitions You Need To Know
Any piece that projects from a firearm for the purpose of attaching something to it.
For example barrel lugs are used to attach a break-action shotgun barrel to the action itself.
If the firearm is a revolver, the term may also refer to a protrusion under the barrel that adds weight,
thereby stabilizing the gun during aiming, mitigating recoil, and reducing muzzle flip. A full lug extends all the way to the muzzle,
while a half lug extends only partially down the barrel. On a swing-out-cylinder revolver, the lug is slotted to accommodate the ejector rod.
An inert ammunition-shaped object, used in practice to simulate misfeeds and other malfunctions. Some folks also use them during dry fire practice to cushion the firing pin as it strikes.
The process of a bullet expanding under pressure to fit the bore of the firearm, or a cartridge case expanding under pressure to seal the chamber.
A name for any palm sized handgun which fires a small caliber.
On semi-auto matic pistols, a lever that mechanically lowers the hammer without firing the gun.
The area of a gun range where firearms are pointed when they are fired. The area of the range forward of the firing line.
Abbreviation for Long Rifle. Typically used in the .22 caliber cartridge designation .22LR. However can be used as an abbreviation for Kentucky Long Rifle
A safety which is placed within the gun and is not accessible to the user. Internal safeties are generally designed to prevent unintentional discharges when the gun is dropped or mishandled.
The distance between the rear sight and the front sight. As a longer lever provides greater mechanical advantage, the greater the distance between the two sights, the more inherently accurate they will be.
An unexpected and undesirable discharge of a firearm caused by circumstances beyond the control of the participant(s) such as a mechanical failure or parts breakage.
There are very, very few firearms related "accidents" and if the "Three Rules" are followed there will hopefully be no injury.
Accidental Discharge should not be confused with "Negligent Discharge".
The setting on the sights used to accommodate the wind or adjust for horizontal (side-to-side) errors in the alignment of the sights with the bore of the firearm.
A fouling shot is a shot fired through a clean bore, intended to leave some residue of firing and prepare the bore for more consistent performance in subsequent shots.
The first shot through a clean bore will behave differently from subsequent shots through a bore with traces of powder residue, resulting in a different point of impact.
A floppy, limp wrist while shooting.
An action type that when the trigger is pulled, the only thing the trigger does is drop the hammer (or striker).
This applies to both revolvers, semi-automatic and automatic guns.
On a single action revolver, the gun must be manually cocked before it can be fired.
With semi-automatic and automatic guns that are single action, the only thing the trigger does is drop the hammer, striker or firing pin onto the cartridge.
Then the firearm is cocked again when from the recoil of the fired round.
A firearm that the gun is cocked and the hammer drops when the trigger is pulled is a double action gun.
A type of internal safety that prevents the firing pin from moving forward for any reason unless the trigger is pulled.
A stun grenade, also known as a flash grenade, is a non-lethal explosive device used to temporarily disorient an enemy's senses.
It is designed to produce a blinding flash of light and intensely loud noise "bang" of greater than 170 decibels (dB)
without causing permanent injury. It was first developed by the British Army's SAS in the 1960s.
The flash produced momentarily activates all photoreceptor cells in the eye, making vision impossible for approximately five seconds,
until the eye restores itself to its normal, unstimulated state. The loud blast is meant to cause temporary loss of hearing,
and also disturbs the fluid in the ear, causing loss of balance.
The concussive blast of the detonation can still injure, and the heat created can ignite flammable materials such as fuel.
The fires that occurred during the Iranian Embassy siege in London were caused by stun grenades.
Recoil operation is an operating mechanism used in locked-breech, autoloading firearms. As the name implies, these actions use the force of recoil to provide energy to cycle the action.
A needle like metal part of a modern firearm that gives a vigorous strike to the primer initiating the firing of the cartridge.
