Bottom Metal
A bottom metal is a firearm component typically made of metallic material (such as aluminium alloy or steel), that serves as the floor of the action and also helps to clamp the receiver onto the stock. The bottom metal also frequently incorporates the trigger guard, for instance on the Mauser 98 and M1 Garand, although a trigger guard by itself is ''not'' considered a bottom metal. In repeating firearms with internal magazines, the bottom metal serves as the magazine floorplate and contains the spring and follower, either as a fixed solid piece or can be opened like a hinged door. Bottom metals designed to accept detachable magazines are called detachable bottom metals (DBM), and contains a rectangular reception slot called the ''magazine well'', with a latch mechanism that securely holds the inserted magazine in place. Single-shot firearms (e.g. SIG Sauer 200 STR) typically do not have bottom metals, and modern firearms with metallic chassis (e.g. SIG Sauer CROSS) do not h ...

Spring (device)
A spring is an elastic object that stores mechanical energy. In everyday use the term often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel, although some non-metallic objects like the bow are also springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve. An extension or compression spring's rate is expressed in units of force divided by distance, for example or N/m or lbf/in. A torsion spring is a spring that works by twisting; when it is twisted about its axis by an angle, it produces a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accuracy International
Accuracy International is a British firearms manufacturer based in Portsmouth, Hampshire, England. The company produces the Accuracy International Arctic Warfare series of precision sniper rifles. The company was established in 1978 by British Olympic shooting gold medallist Malcolm Cooper, MBE (1947–2001), Sarah Cooper, Martin Kay, and the designers of the weapons, Dave Walls and David Caig.

Remington 700
The Remington Model 700 is a series of bolt-action centerfire rifles manufactured by Remington Arms since 1962. It is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948. The M24 and M40 military sniper rifles, used by the US Army and Marine Corps, respectively, are both based on the Model 700 design. The Remington 700 series rifles often come with a 3-, 4- or 5-round internal magazine depending on the caliber chambered, some of which have a hinged floor-plate for quick unloading, and some of which are "blind" (with no floor-plate). The rifle can also be ordered with a detachable box magazine. The Model 700 is available in many different stock, barrel and caliber configurations, with many third-party and aftermarket variants in the market built on the same action footprint. From 1978 to 1982, Remington offered the Sportsman 78 which is the same model 700 action but with cheaper features such as a plain stock without checkering. The Sport ...

Aftermarket (merchandise)
In economic literature, the term "aftermarket" refers to a secondary market for the goods and services that are 1) complementary or 2) related to its primary market goods ( original equipment). In many industries, the primary market consists of durable goods, whereas the aftermarket consists of consumable or non-durable products or services. Accordingly, the "aftermarket goods" mainly include products and services for replacement parts, upgrade, maintenance and enhancement of the use of its original equipment. Examples of durable goods and their associated aftermarket goods and services include: razor handle mounts and disposable razor blades designed to mount in that handle; computer printers and their matching printer cartridges; and new cars and optional upgrades that can be installed after the car is purchased, such as car stereos or fog lights. Elements There are two essential elements of the aftermarket: installed base and lock-in effect. Installed base A certain level ...

Chassis
A chassis (, ; plural ''chassis'' from French châssis ) is the load-bearing framework of an artificial object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis. Examples of use Vehicles In the case of vehicles, the term ''rolling chassis'' means the frame plus the "running gear" like engine, transmission, drive shaft, differential and suspension. An underbody (sometimes referred to as "coachwork"), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle. For commercial vehicles, a rolling chassis consists of an assembly of all the essential parts of a truck without the body to be ready for operation on the road. A car chassis wi ...

The rifle stocks are however factory fitted to a particular rifle, so stocks can n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-shot
Single-shot firearms are firearms that hold only a single round of ammunition, and must be reloaded manually after every shot. The history of firearms began with single-shot designs, then multi-barreled designs appeared, and eventually many centuries passed before multi-shot repeater designs became commonplace. Compared to repeating firearms, single-shot designs have no moving parts (other than the trigger and hammer/firing pin or frizzen) and thus do not need a sizable receiver behind the barrel, and are much less complex than revolvers or magazine/belt-fed firearms. Although largely disappeared from military usage due to the slow rates of fire, single-shot designs are still produced by many manufacturers in both cartridge- and non-cartridge varieties, from zip guns to the highest-quality hunting and match guns. History Pre-cartridge era The vast majority of firearms before the introduction of metallic cartridges from the 1860s onwards, were single-shot muzzleloaders ...

Latch
A latch or catch (called sneck in Northern England and Scotland) is a type of mechanical fastener that joins two (or more) objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a ''keeper'' or ''strike''. A latch is not the same as the locking mechanism of a door or window, although often they are found together in the same product. Latches range in complexity from flexible one-piece flat springs of metal or plastic, such as are used to keep blow molded plastic power tool cases closed, to multi-point cammed latches used to keep large doors closed. Common types Deadbolt latch A single-throw bolt. The bolt can be engaged in its strike plate only after the door is closed. The locking mechanism typically prevents the bolt from being retracted by force. Spring latches * Latch bolt An extrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detachable Magazine
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a "clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-automa ...

Hinge
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other Translation (geometry), translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of Flexure bearing, flexible material or of moving components. In biology, many joints function as hinges, like the elbow joint. History Ancient remains of stone, marble, wood, and bronze hinges have been found. Some date back to at least Ancient Egypt. In Ancient Rome, hinges were called wikt:cardo#Latin, cardō and gave name to the goddess Cardea and the main street Cardo. This name cardō lives on figuratively today as "the chief thing (on which something turns or depends)" in words such as ''wikt:cardinal#English, cardinal''. According to the OED, the English word hinge is related to ''wikt:hang#English, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
