Accurizing
Accurizing is the process of improving the accuracy and precision of a gun (firearm or airgun). For shooting sport, accuracy is the gun's ability to hit exactly what the shooter is aiming at, and precision is the ability to hit the same place over and over again in a repeatable fashion. Both are the goals of accurizing, which generally concentrates on four different areas: *Usability: Enhancements that give the shooter a firmer and more controlled hold on the firearm, as well as a more consistent trigger (firearms), trigger pull. Better design ergonomics is often employed, such as adjustable buttstocks and grips with more vertical angles that are natural to the human hand and wrist (e.g. pistol grip). Spirit levels are often mounted to prevent cant (shooting), canting, which can vary the points of impact. Weapon mounts such as bipods, monopod#Firearms, monopods, benchrests, shooting sticks (weapon mount), shooting sticks or simply sandbags can provide a more stable and relaxed pla ...

Trigger (firearms)
A trigger is a mechanism (engineering), mechanism that Actuator, actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a animal trap, trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flat or slightly curved lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on crossbow#Medieval Europe, medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer ...

Buttstock
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock, or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle Bedding
Rifle bedding is a gunsmithing process of providing a rigid and consistent foundation for a rifle’s operational components, by creating a stable and close-fitting bearing surface between the gun's functional parts (i.e. the receiver housing the barrelled action) and its structural support (i.e. the stock) that do not deform with heat, pressure and moisture, or shift under the shear stress of the recoil from firing. The bedding process is often an aftermarket modification, and is done for the goal of accurizing the rifle and (to a lesser extent) prolonging the service life of the stock. Purpose Increasing accuracy Bedding increases accuracy in part by relieving stress on the action. The rifle's action will rarely sit flush in the stock without bedding. This causes the action to flex when tightening the fixing screws that hold the action to the stock. If the stock is wooden, it will also expand or shrink significantly with environmental changes such as temperature and mois ...

Recoil Compensator
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article o ...

Gun Barrel
A gun barrel is a crucial part of gun-type weapons such as small arms, small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end (muzzle (firearms), muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its calibre, usually measured in inches or millimetres. The first firearms were made at a time when metallurgy was not advanced enough to cast tubes capable of withstanding the explosive forces of early cannons, so the pipe (often built from staves of metal) needed to be braced periodically along its length for structural reinforcement, producing an appearance somewhat reminiscent of storage barrels being stacked together, hence the English name. History Gun barrels are usually made of some type of metal or Alloy, metal alloy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headspace (firearms)
In firearms, headspace is the distance measured from a closed chamber's breech face to the chamber feature that limits the insertion depth of a cartridge placed in it. Used as a verb by firearms designers, ''headspacing'' refers to the act of stopping deeper cartridge insertion. The exact part of the cartridge that seats against the limiting chamber feature differs among cartridge and gun designs. Davis, William C., Jr. ''Handloading'' (1981) National Rifle Association pp.67-69 In general, bottleneck rifle cartridges headspace on their case shoulders; rimmed cartridges headspace on the forward surfaces of their case rims; and rimless pistol cartridges headspace on their case mouths. The case belts on belted cartridges were originally added to allow headspacing on the belt's forward surface, But in practice, this is often vestigial, and rifles chambered for belted cartridges may well headspace them on their shoulders and still be within CIP or SAAMI dimensional limits.

Seal (mechanical)
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leak, leakage (e.g. in a wikt:pumping, pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets. The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications. A stationary seal may also be referred to as a 'packing'. Seal types: *Induction sealing or cap sealing *Sealant, Adhesive, sealant *Bodok seal, a specialized gas sealing washer for medical applications *Bonded seal, also known as Dowty Group, Dowty seal or Dowty washer. A type of Washer (hardware), washer with integral gasket, widely used to provide a seal at the entry point of a screw or bolt *Bridgman seal, a piston sealing mechanism that creates a high pressure reservoir from a lower pressure ...

Note the curved handle on the side for manual operation thumb"> Slide locked back on a Desert Eagle pistol, showing the gas-operated rotating bolt mechanism A bolt is the part of a repeating, breechloading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The firing pin and extractor are often integral parts of the bolt. The terms "breechblock" and "bolt" are often used interchangeably or without a clear distinction, though usually, a bolt is a type of breechblock that has a nominally circular cross-section. In most automatic firearms that use delayed blowback, recoil, or gas operation, the bolt itself is housed within the larger bolt carrier group (BCG), which contains additional parts that receives rearward push from a gas tube ( direct impingement) or a gas piston (short-stroke or lon ...

Savage Arms
Savage Arms is an American gunmaker based in Westfield, Massachusetts, with operations in Canada and China. Savage makes a variety of Rimfire ammunition, rimfire and centerfire rifles, as well as Stevens single-shot rifles and shotguns. The company is best known for the Savage Model 99, Model 99 lever-action rifle, no longer in production, and the .300 Savage. Savage was a subsidiary of Vista Outdoor until 2019 when it was spun off. History Savage Arms was founded in 1894 by Arthur William Savage, Arthur Savage in Utica, New York. Within 20 years they were producing rifles, handguns, and ammunition. Savage introduced the first hammerless lever-action rifle, the Savage Model 99, Model 1895, derived from Arthur Savage's Model 1892 rifle that he had designed for Colt's Manufacturing Company, Colt in a failed bid for a US Army rifle contract that instead was won by the Krag–Jørgensen design. The Model 1895 won a New York National Guard contract, but the contract was cancelled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Action (firearms)
In firearms terminology, an action is the functional mechanism of a breechloading firearm that handles (loads, locks, fires, extracts, and ejects) the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the ''lock'' (e.g. matchlock, wheellock, flintlock, and caplock). Actions can be categorized in several ways, including single action versus double action, break action versus lever-action, pump-action, bolt-action, among many other types. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of or smaller. The long action rifle can accommodate a cartridge of , ...
