Sauer 90
Sauer 80, 90 and 92 are bolt-action rifles using a non-rotating bolt with rear-locking lugs expanded against matching lugs inside the rear of the action by rotating the bolt handle down. The rifle is known for having a relatively short-for-the-calibre and very smooth bolt travel and has been described as “The most accurate rifle ever made,” and “These are the smoothest actions you will ever cycle. They are remarkably accurate.” but also for being technically more complicated than the “Gold Standard” Mauser 98 bolt action. The early European and Colt models had a very complicated trigger mechanism and this was later changed in production to a standard shotgun single-set trigger to give adequate safety with simplicity and familiarity of use. In Europe the rifle was originally sold under the name Sauer 80. The rifle was sold in USA as Sauer Colt from 1973 to 1985, and Browning had a special model with steel panels between 1979 and 1984. Sauer 90 and 92 were later and upd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Repeating Rifle
A repeating rifle is a single-barreled rifle capable of repeated discharges between each ammunition reload. This is typically achieved by having multiple cartridges stored in a magazine (within or attached to the rifle) and then fed individually into the chamber by a reciprocating bolt, via either a manual or automatic action mechanism, while the act of chambering the round typically also recocks the hammer/ striker for the following shot. In common usage, the term "repeating rifle" most often refers specifically to manual repeating rifles (e.g. lever-action, pump-action, bolt-action, etc.), as opposed to self-loading rifles, which use the recoil, gas, or blowback of the previous shot to cycle the action and load the next round, even though all self-loading firearms are technically a subcategory of repeating firearms. Repeating rifles were a significant advance over the preceding single-shot, breechloading rifles when used for military combat, as they allowed a much grea ...

Modular Weapon System
A modular weapon system (MWS) is any weapon equipment which has removable core components (or " modules") that can be reconfigured/interchanged to give the weapon different capabilities to adapt to various applications. Modularity can provide several advantages to military organizations, such as the versatility of allowing units to quickly tailor their weapons to best suit the immediate tactical needs, to quickly repair/exchange malfunctioned components, and to reduce overall logistical burdens and costs. However, it also make the legal tracking and technical categorization of a weapon more complicated as it can now be easily converted into a diverse variety of different forms.* For example, the Stoner 63 is a 5.56×45mm NATO-caliber modular small arm system using a variety of modular components, which can be configured as a rifle, a carbine, a top-fed light machine gun, a belt-fed squad automatic weapon, or a vehicle mounted weapon. A modular firearm can also be useful for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrench
A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning. In the UK, Ireland, Australia, and New Zealand ''spanner'' is the standard term. The most common shapes are called ''open-ended spanner'' and ''ring spanner''. The term ''wrench'' is generally used for tools that turn non-fastening devices (e.g. tap wrench and pipe wrench), or may be used for a monkey wrench—an adjustable pipe wrench. In North American English, ''wrench'' is the standard term. The most common shapes are called ''open-end wrench'' and ''box-end wrench''. In American English, ''spanner'' refers to a specialized wrench with a series of pins or tabs around the circumference. (These pins or tabs fit into the holes or notches cut into the object to be turned). In American commerce, such a wrench may be called a ''spanner wrench'' to distinguish it from the British sense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vise
A vise or vice (British English) is a mechanical apparatus used to secure an object to allow work to be performed on it. Vises have two parallel jaws, one fixed and the other movable, threaded in and out by a screw and lever. The jaws are often flat but may have grooves, adapt to the shape of the workpiece or be custom made. A vise grip is not a vise but a pair of lever-actuated locking pliers. Etymology The etymology of ''vise'' can be tracked via Middle English ''vys'' Anglo-French ''vyz'' from Latin ''vitis'' "vine". The tight grip of the mechanical device was likened to that of the twines of the plant. Types Face A face vise is the standard woodworking vise, always securely attached to a workbench flush with its work surface. Its jaws are made of wood or metal, the latter usually faced with wood, called cheeks, to avoid marring the work. The movable jaw may include a retractable dog to hold work against a bench dog. A "quick-release" woodworker's vise employs a split ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hex Key
A hex key (also, hex wrench, Allen key and Allen wrench, Unbrako or Inbus) is a simple driver for Bolt (fastener), bolts or screws that have heads with ''internal'' hexagonal recesses (Socket wrench, sockets). Hex keys are formed from a single piece of hard hexagonal steel rod, having blunt ends that fit snugly into similarly shaped screw sockets. The rods are bent to 90°, forming two arms of unequal length resembling an "L". The tool is usually held and twisted by its long arm, creating a relatively large torque at the tip of the short arm; it can also be held by its short arm to access screws in difficult-to-reach locations and to turn screws faster at the expense of torque. Hex keys are designated with a socket size and are manufactured with tight tolerances. As such, they are commonly sold in kits that include a variety of sizes. Key length typically increases with size but not necessarily proportionally so. Variants on this design have the short end inserted in a trans ...

Action Threads
In firearms, barrel threads refer to the screw threads used to attach a barrel. Action threads, also called receiver threads, are situated at the chamber end of the barrel, and can be used for attaching the barrel to the receiver. The receiver normally has corresponding threads which are internal, with the matching action threads on the barrel usually being external threads. This design is most commonly used in rifles and revolvers, but also on some pistols and shotguns. This method of fixing a barrel to a receiver has been used extensively by firearms manufacturers since before the 20th century, and can be viewed as a traditional barrel mounting method. Action threads are not the only method of fixing a barrel to a receiver (see ''Alternative methods'' below). Furthermore, recoil-operated firearm designs have moving barrels (e.g. most pistols or the Barrett M82 rifle). Muzzle threads are situated at the muzzle end of the barrel and can be used for mounting accessories such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

458 Winchester Magnum
The .458 Winchester Magnum is a belted, straight-taper cased, Big Five game rifle cartridge. It was introduced commercially in 1956 by Winchester and first chambered in the Winchester Model 70 African rifle. It was designed to compete against the .450 Nitro Express and the .470 Nitro Express cartridges used in big bore British double rifles. The .458 Winchester Magnum remains one of the most popular large game cartridges, and most major ammunition manufacturers offer a selection of .458 ammunition. History The .458 Winchester Magnum was designed for hunting dangerous game animals by emulating the performance of powerful English double rifle cartridges in a bolt-action rifle. The use of a bolt-action rifle offered hunters a cheaper alternative to the big-bore double rifle, and ammunition could be manufactured using available tooling. The .458 Winchester Magnum soon became a success as dangerous game hunters adopted the cartridge. Soon, game wardens, wildlife managers, and ...

375 H&H Magnum
__NOTOC__ Year 375 ( CCCLXXV) was a common year starting on Thursday of the Julian calendar. At the time, it was known in Rome as the Year after the Consulship of Augustus and Equitius (or, less frequently, year 1128 ''Ab urbe condita''). The denomination 375 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

300 Weatherby Magnum
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...
