Sniper Rifle
A sniper rifle is a high-precision, long range shooting, long-range rifle. Requirements include high accuracy, reliability, mobility, concealment, and optics, for anti-personnel weapon, anti-personnel, anti-materiel rifle, anti-materiel and surveillance uses by military snipers. The modern sniper rifle is a portable shoulder-fired rifle with either a bolt action or semi-automatic firearm, semi-automatic action (firearms), action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance Centerfire ammunition, centerfire cartridge (firearms), cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed in 1854 by Sir Joseph Whitworth, a prominent British engineer, it used barrels with hexagonal polygonal rifling, which meant that the projectile did not have to "bite" into the rifling grooves as with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt (firearms)
Bolt from a Karabiner 98k bolt-action rifle. 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 o ...

Flash Hider
A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances that the shooter will be blinded in low-light shooting conditions. Contrary to popular belief, it is only a minor secondary benefit if a flash suppressor reduces the intensity of the flash visible to the enemy. A flash suppressor is different from a muzzle brake, although they are typically mounted in the same position and sometimes confused with each other. While the former is intended to reduce visible flash, a muzzle brake is designed to reduce recoil inherent to large cartridges and typically does not reduce visible flash. Rationale Pre-20th century rifle designs tended to have longer barrels than modern rifles. A beneficial side eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handguard
A barrel shroud is an external covering that envelops (either partially or full-length) the barrel of a firearm to prevent unwanted direct contact with the barrel (e.g. accidental collision with surrounding objects or the user accidentally touching a hot barrel, which can lead to burns). Moving coverings such as pistol slides, fore-end extensions of the gunstock/chassis that do not fully encircle the barrel, and the receiver (or frame) of a firearm itself are generally not described as barrel shrouds, though they can functionally act as such. In shotguns, a thin, slim partial shroud known as a rib is often mounted above the barrel to shield away the mirage generated by barrel heat, which can interfere with aiming. Full-length barrel shrouds are commonly featured on air-cooled machine guns, where frequent rapid bursts or sustained automatic fire will leave the barrel extremely hot and dangerous to the user. However, shrouds can also be used on semi-automatic firearms, espe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picatinny Rail
The 1913 rail (MIL-STD-1913 rail) is an American rail integration system designed by Richard Swan that provides a mounting platform for firearm accessories. It forms part of the NATO standard STANAG 2324 rail. It was originally used for mounting of telescopic sights atop the receivers of larger caliber rifles. Once established as United States Military Standard, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser sights, night-vision devices, reflex sights, holographic sights, foregrips, bipods, slings and bayonets. An updated version of the rail is adopted as a NATO standard as the STANAG 4694 NATO Accessory Rail. History Attempts to standardize the Weaver rail mount designs date from work by the A.R.M.S. company and Richard Swanson in the early 1980s. Specifications for the M16A2E4 rifle and the M4E1 carbine received type classification generic in December 1994. These were the M16A2 and the M4 modified wi ...

Weaver Rail Mount
A Weaver rail mount is a system to connect telescopic sights (often via a scope mount) and other accessories to firearms and certain crossbows. It uses a pair of parallel rails and several slots perpendicular to these rails. The later Picatinny rail, developed by the US military, is a development of the key concepts of the Weaver system, and they are partially compatible. History The Weaver mount was developed by William Ralph Weaver (1905 – 8 November 1975) at his telescopic sight company W.R. Weaver Co., which he founded in 1930. Previous systems included the Leupold & Stevens, Leupold/Redfield mounts. Compared to the Leupold mount, the Weaver rail is not as strong and cannot be adjusted for windage. W.R. Weaver Co. became Weaver Optics, and was a subsidiary of Meade Instruments, Meade Instruments Corporation from 2002 to 2008, when it was on-sold to become part of Alliant Techsystems's Security and Sporting division in Onalaska, Wisconsin.

Carbon Fiber Reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers ( Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but oth ...

M1 Garand
The M1 Garand or M1 rifleOfficially designated as U.S. rifle, caliber .30, M1, later simply called Rifle, Caliber .30, M1, also called US Rifle, Cal. .30, M1 is a semi-automatic rifle that was the service rifle of the United States Army, U.S. Army during World War II and the Korean War. The rifle is chambered for the .30-06 Springfield cartridge and is named after its Canadian Americans, Canadian-American designer, John Garand. It was the first standard-issue autoloading rifle for the United States. By most accounts, the M1 rifle performed well. General George S. Patton called it "the greatest battle implement ever devised". The M1 replaced the (bolt-action) M1903 Springfield as the U.S. service rifle in 1936, and was itself replaced by the (selective fire, selective-fire) M14 rifle on 26 March 1958. Pronunciation Sources differ on the pronunciation of the M1 Garand. Some, such as General Julian Hatcher, Julian Hatcher's ''The Book of the Garand'' (1948), give , identical to ...

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 ...

Lock Time
Lock time or action time refers to the time interval (often measured in milliseconds) from when the Trigger (firearms), trigger of a firearm is activated until the firing pin strikes the Primer (firearms), primer, and depends on the design of the firing mechanism. A long lock time increases the probability of the shooter pulling the sights away from the target before the bullet has left the barrel, a common shooter error which can lead to poor hits or even misses. Shooters can therefore tend to experience better precision using firearms with a shorter lock time, and short lock times are especially sought after for Shooting sports, shooting competitions which require high precision on small targets from unstable positions, such as the standing offhand position. Measuring lock time The lock time can be measured electronically, but is often instead calculated mathematically by the manufacturer. Important mathematical design parameters taken into consideration is the Hooke's law, spr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karabiner 98k
The Karabiner 98 kurz (; ), often abbreviated Karabiner 98k, Kar98k or K98k and also sometimes incorrectly referred to as a K98 (a K98 is a Polish carbine and copy of the Kar98a), is a bolt-action rifle chambered for the 7.92×57mm Mauser cartridge. It was adopted on 21 June 1935 as the standard service rifle by the German ''Wehrmacht.''K98k Mauser Page Retrieved 28 March 2007. It was one of the final developments in the long line of Mauser military rifles. Although supplemented by semi-automatic and fully automatic rifles during World War II, the Karabiner 98k remained the primary German military rifles, German service rifle until the end of the war in 1945. Millions were captured by the Soviets at the conclusion of World War II and were widely distributed as military aid. The Karabiner 98k therefore continues to appe ...
