The Definition of Recoil Spring
The recoil spring is the powerful spring that cushions the slide in its rearward travel and then sends the slide forward again with enough force to drive the fresh round firmly into the chamber.
The strength of the recoil spring is calibrated to run the slide without any outside assistance.
19 Other Firearms Definitions You Need To Know
Ammunition that has been assembled by a commercial vendor of ammunition and sold in retail stores. This is as opposed to Hand loads which have been assembled by individuals and are not typically sold.
A rifle or carbine with a one-piece stock extending to the muzzle. Sometimes called a Mannlicher stock,
although such a term is confusing because Mannlicher Schoenauer rifles are built with both full and half stocks.
Traditional in Europe for close-range woodland hunting, but not noted for extreme, long-range accuracy.
The point of the trigger's return at which the gun's internal mechanisms are ready to fire another round.
The vise-like device on a flintlock hammer used to hold the flint.
A rifle front sight with a extra-large, folding bead. Typically, in addition to the normal fine bead (which allows for more precision) the larger bead,
while at a cost of potential accuracy, is more readily acquired in marginal light. Also called a Gloaming sight
A system of firearms ignition, in general use circa 1660 - 1825, whereby the pull of a trigger releases a sear from a notch in a spring-loaded hammer,
which holding a properly knapped piece of flint, strikes a vertical slab of steel (called a frizzen) scraping off tiny molten particles of the steel,
and pushing it forward causes an integral flashpan cover to open forward, exposing a bit of fine gunpowder below, which when contacted by the falling sparks,
ignites and sends a flash of fire through the touchhole, into the loaded breech setting off the main charge and firing the gun.
The Flintlock system was supplanted by the Percussion system around 1820.
That part of the stock on a rifle or shotgun into which the barrel fits.
The length, within a rifled barrel, required to accomplish one full rotation. 1:12 Twist, means a bullet passing down the bore would complete one revolution in twelve inches.
1:7 Twist, means a bullet passing down the bore would complete one revolution in seven inches, which makes it a tighter twist than 1:12.
Different weights of bullet require appropriate rates of twist.
A firing pin which moves freely forward and backward in the breechblock.
A part in a firearm that serves to remove brass cases of fired ammunition after the ammunition has been fired.
When the gun's action cycles, the extractor lifts or removes the spent brass casing from the firing chamber.
Abbreviation for Concealed Carry Permit.
The term referring to the action of manually drawing the hammer back against its spring until it becomes latched against the sear,
or sometimes the trigger itself, arming the hammer to be released by a subsequent pull of the trigger. Some external hammers, and all internal hammers,
may be cocked simply by pulling the trigger
The top of a gun's stock, where a shooter rests his cheek when mounting a gun.
As it is the top of the stock that determines the position of
one's eye, and one's eye is the rear sight on a shotgun, the position of the comb
is very important in determining the proper fit of a shotgun.
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 arc described by a projectile (or a load of shot) after it exits the muzzle of a firearm. Falling objects accelerate downwards at a rate of 32 feet per second, per second.
The faster a projectile travels, the greater the distance it can cover in a given time before dropping too far. Hence, the higher the velocity of a bullet, the flatter the trajectory it will achieve.
The detachable plate at the bottom of the cartridge magazine.
The National Rifle Association. This organization coordinates shooting events on a national level, provides firearms training to civilians and law enforcement,
fights restrictive firearms legislation and supports the constitutional right of law abiding citizens to own and carry firearms.
A small lever mounted to the cocking piece of a Mauser 98 action (and its copies such as the Springfield 1903),
rotating on a longitudinal axis from left (Fire), up to the top (Safe, but allowing bolt movement), and over to
the right (Bolt and firing pin locked Safe). While commendable for locking the firing pin instead of just the trigger,
its up-and-over arc of operation requires a scope to be mounted awkwardly high.
Paul Mauser is not to be blamed; when his safety was developed, telescopic sights were in such infancy as not to be worthy of mainstream consideration.
A volume of fire delivered by a military unit. Incorrectly used by the media to mean the ability of a small arm to be discharged many times without reloading.
