Hello everyone, this is the biggest firearm thread is currently available.
Try to keep this thread away from the political bullshit.
WHAT IS A FIREARM?
A firearm is a device that shoots projectiles at a high velocity with a controlled explosion. Gun may be a commonly used term, but gun is a generalization of cannons, artillery pieces, and auto cannons.
The propellant is typically mixed with a deterrent, something to slow down the burning, allowing for a more controlled burn. Primers, which are used to ignite the propellant, are typically made out of these impact sensitive materials:
- Mercury Fulminate
- Lead Azide
- Potassium Perchlorate
The case, which is used to hold all of the components of the cartridge together, is typically made out of brass (more commonly) or steel (with brass primers). Bullets are typically made out of lead or steel, and the jacketing (a metal coating that goes around the bullet) is made out of copper.
Also part of the gun is the action. The action is how the gun loads the cartridge into the chamber, and repeats.In firearms terminology, an action is the physical mechanism that manipulates cartridges and/or seals the breech. The term is also used to describe the method in which cartridges are loaded, locked, and extracted from the mechanism. Actions are generally categorized by the type of mechanism used. A firearm action is technically not present on muzzleloaders as all loading is done by hand. The mechanism that fires a muzzle-loader is called the lock.
Breech: Where the round is put in
Bore: Inner Diameter of a Firearm
Bolt: Is a piece of metal in the reciever that moves back and forth, striking the primer on the pull of the trigger
Types of Actions:
There are two types of actions, automatic and manual
WHAT IS A FIREARM USED FOR?
Firearms are used for three main things: 1. Killing 2. Hunting 3. Sporting (Not in order of usage)
HOW DOES A FIREARM WORK?
Most modern firearms use a cartridge for containing the propellant, primer, and bullet. Propellants, which is used to act as gunpowder in the cartridge, is typically made out of these compounds:
Manual actions:Falling block
A falling block action is a type of single shot firearm where the opening and closing of the breech is activated by a lever acting directly on the breechblock and lowering it to expose the breech. An example of a firearm using the falling block action are the Martini-Henry and Ruger No. 1. A minor variation is the rolling block where the breechblock is pivoted out of the way.
A revolver houses cartridges in a rotary cylinder and advances them in-line with the bore prior to each shot. Revolvers are most often handguns however examples of rifles and shotguns have been made. The cylinder is most often rotated by manipulation of the trigger and/or hammer although some are semi-automatic using recoil to rotate the cylinder and cock the hammer.
In bolt action firearms, the opening and closing of the breech is operated manually by a bolt. Opening the breech ejects a cartridge while subsequently closing the breech chambers a new round. The three predominant bolt-action systems are the Mauser, Lee-Enfield, and Mosin-Nagant systems.
Lever action firearms uses a lever to eject and chamber cartridges. An example of firearms using lever action are the Winchester Repeating Rifle and Marlin Model 1894.
In pump action or slide action firearms, a grip called the fore end is manually operated by the user to eject and chamber a new round. Pump actions are predominantly found in shotguns. An example of firearms using the pump action are the Remington 870 and Winchester Model 1897
A break action is a type of firearm where the barrel(s) are hinged and can be "broken open" to expose the breech. Multi-barrel break action firearms are usually subdivided into over-and-under or side-by-side configurations for two barrel configurations or "combination gun" when mixed rifle and shotgun barrels are used.
Recoil operation is a type of locked-breech firearm action used in semi-automatic and fully-automatic firearms. As the name implies, these actions use the force of recoil to provide the energy to cycle the action.
Examples of recoil operation
Short-recoil: Colt M1911, CZ75, Browning Hi-Power, HK USP, Glock, M2 Browning machine gun, MG42, Ceska Zbrojovka Vz 52, M82
Long-recoil: Browning Automatic Shotgun, Femaru STOP Pistol, Mars Automatic Pistol
Inertia: some Benelli shotguns
Blowback operation is a system in which semi-automatic and fully-automatic firearms operate through the energy created by combustion in the chamber and bore acting directly on the bolt face through the cartridge.
Blow-Forward operation is where the firearm has a moving barrel that is forced forward against a spring by the friction of the projectile as means of reloading a fresh round.
Examples of blowback operation
Simple blowback: MP 40, Uzi submachine gun, Walther PPK
Roller-delayed blowback: SIG 510, HK MP5, HK P9
Gas-delayed blowback: Volkssturmgewehr 1-5, HK P7, Steyr GB
Lever-delayed blowback: FAMAS, AA-52
*no picture sorry*
Toggle-delayed blowback: Schwarzlose MG M.07/12 and Pedersen rifle
*no picture sorry*
Blow-forward: Steyr Mannlicher M1894, Schwarzlose Model 1908
*no picture sorry*
Blish Lock: early Thompson submachine guns
*again, no pictues*
Hesitation locked: Remington 51 pistol
*no goddamn pictures*
Chamber-ring delayed blowback: Seecamp pistol
Gas operation is a system of operation used to provide energy to semi-automatic and fully-automatic firearms. In gas-operation, a portion of high pressure gas from the cartridge being fired is used to extract the spent case and chamber a new cartridge. There are three basic types: long stroke gas piston (where the gas piston goes the same distance as the operating stroke of the action parts, and is often attached to the action parts), short stroke gas piston (where the gas piston goes less than distance as the operating stroke of the action parts), and direct impingement (AKA "direct gas", "gas impingement", where there is no piston, and the gas acts directly on the action parts). A fourth type, now considered obsolete and ineffective, are those systems based on the Bang rifle that utilize a muzzle cap to capture gas after the bullet has left the barrel. While this system is successful in boosting the operating power of recoil operated guns, it is insufficient and too susceptible to fouling for use as the primary operating system.
Examples of gas operation
Short-stroke gas piston: FN FAL, HK G36
Long-stroke gas piston: M1 Garand, AK-47
Gas trap: Gewehr 41, Bang M1922 rifle
The parts of a rifle are this:
I assume most of you know what the stock and the barrel is, so I will only explain the receiver.
Pretty much the receiver is where the the action happens. It is where the cartridge casing is ejected, where the bullet is fired, and where the cartridge is loaded into the chamber. To go into further detail, read this:In firearms terminology, the receiver is the part of a firearm that houses the operating parts. It is sometimes called the body of the firearm, and especially in the context of handguns (revolvers and pistols) it is often called the frame. It is often made of forged or stamped steel or aluminum; in addition to these traditional materials, modern materials science and materials engineering have introduced polymers and sintered metal powders to receiver construction.
With MOST pistols, remove the part about the stock.
Clip, magazine, what's the difference?
Well, pretty much a magazine stores bullets, and the clip holds bullets to go into the magazine (with the exception of the en bloc). To go into further detail, read here:One of the most misused terms in firearms is "Clip".
Depending on how you look at it, it is either amusing or pitiful that writers who consider themselves experts or authorities don't know the difference between a magazine and a Clip.
A Clip is a very different thing to a magazine and the terms are not interchangeable.
Saying "Clip" when you mean "magazine" is rather like talking about socks when you mean boots.
A magazine can be defined as a container of ammo. A room full of shells on a battleship is a magazine, and so was the Parthenon when it was used as a powder store.
In small arms terms magazine usually refers to a box, drum or tube with a spring inside to help feed the rounds. Magazines can be a fixed part of the weapon, or detachable. Most detachable magazines can be removed and replaced with a full one to reload the weapon, but there are guns such as the Lee Enfield where the magazine is only removed for cleaning, and is refilled by a different mechanism. (more of this in a moment).
The ammo Clip was invented in 1885 by Mannlicher and provided a way to place a full load of rounds into a magazine in one action. What many people do not appreciate is that the Clip also forms an integral part of the gun's mechanism. If the rounds are not held in a Clip the gun cannot go through the full cycle of chamber, fire and eject.
I have heard the term "Battle Rifle" and "Assault Rifle". What's the difference?
Well, pretty much a the difference is a bigger caliber. The battle rifle is a select-fire rifle that uses a high powered round like the .30-06 or the .308. The assault rifle, on the other hand, uses an intermediate round like the 5.56x45mm NATO or the 7.62x39mm AK round.
Of course, the quote:
A battle rifle is a full-size rifle designed for military use that fires a high-power rifle cartridge such as the U.S. .30-06 Springfield, the German 7.92x57mm IS, the Russian 7.62x54mmR, or the 7.62x51mm NATO cartridge. While the term battle rifle is usually given to post-World War II selective-fire infantry service rifles such as the H&K G3, the FN FAL, the AR-10, or the M14, this term can also include older military bolt-action or semi-automatic rifles such as the Mosin Nagant or the M1 Garand.
An assault rifle is loosely defined as a selective fire rifle designed for combat that uses an intermediate cartridge and a detachable magazine. Assault rifles are the standard infantry weapons in most modern armies. Examples of assault rifles include the M16 rifle, AK family, G36, FN FNC, and the Steyr AUG
Will update with more fresh content when I think of some. I will be checking the comments daily for more suggestions on how to make the OP better.
How are Calibers measured?
Well first off America uses inches to measure their calibers while Europe uses the scientific metric system.
Okay so the caliber measured by the length of the bullet and diameter of the base.
For example, a 9mm Parabellum bullet would be written as 9x19mm. 9 meaning the diameter base, and the 19 meaning the length of the bullet.
Thank you for reading
This took me ages to construct and so i would appreciate a +3
Thanks once again
