Recoil Buffer
A recoil buffer is a factory-installed or aftermarket component of firearms which serves to reduce the velocity and/or cushion the impact of recoiling parts of a firearm. Design The simplest form of recoil buffer is made from a resilient and deformable material (leather, rubber, polymer e.g. a rubber butt pad on a shotgun). A second way of producing a recoil buffer is to insert a spring into the recoil train—the path/part(s) generating recoil impulse. This spring is mounted to the point(s) where the firearm contacts a mechanical holder such as a tripod or human upper torso. Reducing the initial jolt, the rate and/or extent of rearward displacement, and any internal impacts in the operating parts of a firearm can reduce the shooter's perception of recoil, and may also work to extend the life of the mechanism and its parts. More sophisticated designs use hydraulic or pneumatic shock absorbers; systems of springs, cams and levers to modify, dampen, or dissipate the rearward impul ...

Firearms
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. ...

Gas Spring
A gas spring, also known as a gas strut or gas damper, is a type of spring that, unlike a typical mechanical spring that relies on elastic deformation, uses compressed gas contained within an enclosed cylinder. They rely on a sliding piston to pneumatically store potential energy and withstand external force applied parallel to the direction of the piston shaft (loosely analogous similarly to a bicycle pump without a gas outlet). Gas springs are used in automobiles to support hatches, hoods, and covers. They are also used in furniture and doors, as well as in medical beds. They are used industrially in machine tool presses. Fast-acting gas springs are used in aerospace design and weapons applications, and large, extended gas springs are used in passive heave compensators, which stabilize drilling operations against waves. Gas springs are usually implemented in one of two ways. A ''pneumatic suspension'' gas spring directly compresses a chamber of air with the piston. A ''hydro- ...

AK-47
The AK-47, officially known as the Avtomat Kalashnikova (; also known as the Kalashnikov or just AK), is an assault rifle that is chambered for the 7.62×39mm cartridge. Developed in the Soviet Union by Russian small-arms designer Mikhail Kalashnikov, it is the originating firearm of the Kalashnikov rifle, Kalashnikov (or "AK") family of rifles. After more than seven decades since its creation, the AK-47 model and its variants remain one of the most popular and widely used firearms in the world. Design work on the AK-47 began in 1945. It was presented for official military trials in 1947, and, in 1948, the fixed-Stock (gun), stock version was introduced into active service for selected units of the Soviet Army. In early 1949, the AK was officially accepted by the Soviet Armed Forces and used by the majority of the member states of the Warsaw Pact. The model and its variants owe their global popularity to their reliability under harsh conditions, low production cost (compared t ...

M1911
The Colt M1911 (also known as 1911, Colt 1911, Colt .45, or Colt Government in the case of Colt-produced models) is a single-action, recoil-operated, semi-automatic pistol chambered primarily for the .45 ACP cartridge. History Early history and adaptations The M1911 pistol originated in the late 1890s as the result of a search for a suitable self-loading (or semi-automatic) pistol to replace the variety of revolvers in service at the time. The United States was adopting new firearms at a phenomenal rate; several new pistols and two all-new service rifles ( M1892/96/98 Krag and M1895 Navy Lee), as well as a series of revolvers by Colt and Smith & Wesson for the Army and Navy, were adopted just in that decade. The next decade would see a similar pace, including the adoption of several more revolvers and an intensive search for a self-loading pistol that would culminate in the official adoption of the M1911 after the turn of the decade. Hiram S. Maxim had designed a self- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coil Spring
A tension coil spring A coil spring is a mechanical device that typically is used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. It is made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded. Under tension or compression, the material (wire) of a coil spring undergoes torsion. The spring characteristics therefore depend on the shear modulus. A coil spring may also be used as a torsion spring: in this case the spring as a whole is subjected to torsion about its helical axis. The material of the spring is thereby subjected to a bending moment, either reducing or increasing the helical radius. In this mode, it is the Young's modulus of the material that determines the spring characteristics. Spring rate A selection of conical coil springs Spring rate is the measurement of how much load (in pounds) a coil spring can hold until it compresses . The spring r ...

Service Life
A product's service life is its period of use in service. Several related terms describe more precisely a product's life, from the point of manufacture, storage, and distribution, and eventual use. Service life has been defined as "a product's total life in use from the point of sale to the point of discard" and distinguished from replacement life, "the period after which the initial purchaser returns to the shop for a replacement". Determining a product's expected service life as part of business policy ( product life cycle management) involves using tools and calculations from maintainability and reliability analysis. Service life represents a commitment made by the item's manufacturer and is usually specified as a median. It is the time that any manufactured item can be expected to be "serviceable" or supported by its manufacturer. Service life is not to be confused with '' shelf life'', which deals with storage time, or with technical life, which is the maximum period ...

Velocity
Velocity is a measurement of speed in a certain direction of motion. It is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of physical objects. Velocity is a vector (geometry), vector Physical quantity, quantity, meaning that both magnitude and direction are needed to define it. The Scalar (physics), scalar absolute value (Magnitude (mathematics), magnitude) of velocity is called , being a coherent derived unit whose quantity is measured in the International System of Units, SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an ''acceleration''. Definition Average velocity The average velocity of an object over a period of time is its Displacement (geometry), change in position, \Delta s, divided by the duration of the period, \Delt ...
