The Definition of Electronic Hearing Protection
Electronic Hearing Protection
Ear muff or ear plug hearing protection that have internal electronics that amplify human voices while excluding all noises louder than a given decibel rating.
Electronic hearing protection is best used when shooting outdoors. When on an indoor range they have a tendency to pick up too much echo and other muffled sounds.
19 Other Firearms Definitions You Need To Know
A long gun stock that may be doubled over for conveniently compact storage.
The firing mechanism of a a muzzle-loading weapon. In breech-loading firearms, the lock is the firing mechanism and breech-sealing assembly.
A unit of measure traditionally used for black powder shotgun charges. Today, used for smokeless powders on the basis of the new propellant's
equivalent performance to that weight of black powder. Thus, a shotgun shell marked 3 - 1 1/8
would be loaded with the smokeless powder equivalent of 3 drams of black powder, and with 1 ounce of shot. 1 Dram = 1/16 ounce = 437.5 grains.
A straight-wrist grip, typical on English shotguns, built for graceful aesthetics, light weight and fast handling.
Also spelled blueing.
A passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish.
True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite
(Fe3O4), the black oxide of iron, which occupies the same volume as metallic iron. Bluing is most commonly used by gun manufacturers, gunsmiths and gun
owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms.
Same as Follower. A plate, mounted to the top of a spring, inside a magazine, over which cartridges may slide smoothly as they are guided into the chamber of a repeating firearm.
An inexact, non-technical term indicating a magazine holding more rounds than might be considered "average.".
A rib extension on a break-open gun, ending in a circular or semi-circular shape in plan (resembling the head of a doll),
mating into a similarly-shaped recess in the top of the receiver, designed to resist the tendency of
the barrels to pull away from the standing breech when firing.
Because an action's centerpoint of flexing when firing is at the base of the standing breech, not at the hingepin, a passive doll's
head extension makes an effective extra fastener, even without additional mechanical locks operated by the opening lever.
In the Weaver stance,
the body is bladed partly sideways in relation to the target rather than squared towards it (think boxing or martial arts fighter stance).
The elbows are flexed and pointed downward. The strong-side arm is slightly straighter than the weak-side arm.
Even though the legs are not square to tharget, the hips should be square to the target. The feet should be pointed at the target.
The shooter pushes out with the gun hand, while the weak hand pulls back.
This produces a push-pull tension which is the chief defining characteristic of the Weaver stance.
Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge,
normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession,
one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge,
but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.
The opening in the bottom of the gun into which a box magazine is fed. On a semi-auto handgun,
the magazine well is at the base of the grip; on a rifle, it is usually placed in front of the trigger guard.
A sub-field of ballistics, is the study of the behavior of a projectile when it hits its target.
Usually a telescopic firearm sight.
A passive, external safety typically located on the backstrap, which must be fully depressed to release the trigger. Most 1911-pattern pistols feature a grip safety.
The rear portion of the barrel or firing cylinder in which the cartridge is inserted prior to being fired.
Rifles and pistols generally have a single chamber in their barrels,
while revolvers have multiple chambers in their cylinders and no chamber in their barrel.
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.
The unplanned discharge of a firearm caused by a failure to observe the basic safety rules, not a mechanical failure of the gun.
A laser sight is an alternative sighting device which enables the shooter to quickly and accurately see where the firearm is aimed even
when lighting or other conditions prevent using the gun's normal sights. Lasers may be located within the grips,
hung from accessory rails at the front end of the gun, or placed within the firearm.
In the Traditional Isosceles
Both arms are stretched almost equally forward with the gun centered forward.
The knees are straight or only slightly flexed, and the entire body is upright and parallel to the target.
This is an acceptable range stance provided recoil control is not an issue and you don't need to make rapid follow-up shots.
However, if you are practicing for self-defense, you will probably want to use the Modern Isosceles stance stance instead.
