Iver Johnson AMAC-1500
The Iver Johnson AMAC-1500/5100 (aka RAP Model 500 or aka RAI 500 or, depending on source, 'AMAC-1500' or 'AMAC-5100') is a 36 lb manually-operated single-shot sniper rifle/anti-material rifle. The 29" barrel with a massive 7" two-stage muzzle brake on its end (barrel plus muzzle brake OAL of 36") has a 1 in 14" twist rifling rate, an adjustable crisp trigger pull between 3 lbs - 8 lbs, an adjustable stock length of pull between 13.75" to 15.5," and a stock comb adjustable to +1.5" for operator tuning. The rifle featured a removable "shell holder" rotating bolt with three lugs. For each shot, the removable bolt was rotated and removed from the receiver, then a cartridge was inserted into a half-circular retaining ridge breech bolt face, and then bolt with cartridge were inserted back into receiver and locked closed prior to firing pin cocking and firing. As such, there is no 'safety' once the bolt is engaged with a live round other than counter-rotating the bolt from the locked ...

Anti-material Rifle
An anti-materiel rifle (AMR) is a rifle designed for use against military equipment, structures, and other hardware (materiel). Anti-materiel rifles are chambered in significantly larger calibers than conventional rifles and are employed to eliminate equipment such as engines and unarmored or lightly armored targets. While modern armored vehicles are resistant to anti-materiel rifles, the extended range and penetration still has many modern applications. While not intended for use against human targets, the bullet weight and velocity of anti-materiel rifles gives them exceptional long-range capability even when compared with designated sniper rifles. Anti-materiel rifles are made in both bolt-action as well as semi-automatic designs. History The origins of the anti-materiel rifle go back to the First World War, during which the first anti-tank rifles appeared. While modern tanks and most other armored vehicles are too well protected to be affected by anti-materiel rifles, the guns ...

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral 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 on Limcat Under ...

Sniper Rifles Of The United States
A sniper is a military/paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with high-precision rifles and high-magnification optics, and often also serve as scouts/observers feeding tactical information back to their units or command headquarters. In addition to long-range and high-grade marksmanship, military snipers are trained in a variety of special operation techniques: detection, stalking, target range estimation methods, camouflage, tracking, bushcraft, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition. Etymology The name "sniper" comes from the verb "to snipe", which originated in the 1770s among soldiers in British India in reference to shooting snipes, a wader that was considered an extremely challenging game bird for hunters due to its alertness, camouflaging color and ...

5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form ...

Barrett XM109
The Barrett XM109 is a prototype anti materiel sniper rifle, chambered for 25 × 59 mm grenade rounds and developed by Barrett Firearms Manufacturing. It was designed in accordance with a requirement set out in 1994, and is capable of defeating light armor and equipment out to . Prototypes of the XM109 have existed since the late 1990s and studies of the weapon's effectiveness were released in 2002; 10 prototypes were known to exist in 2004, and the XM109 and Barrett XM500 were folded into a broader Anti-Material Rifle Congressional Program in 2006. The current status of the XM109 is not particularly clear, with no news of either cancellation or potential adoption. Overview The XM109, originally known as the Objective Sniper Weapon (OSW) and now called the Anti-Materiel Payload Rifle (AMPR), is a semi-automatic anti-materiel rifle, designed primarily for engagement of light armored vehicles and similar targets. The design uses the lower receiver from an M82/M107, but with a n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrett M95
The Barrett M95 is a bolt-action rifle chambered in .50 BMG (12.7×99mm), and manufactured by Barrett Firearms Company. It has been adopted by a number of militaries around the world. Overview The M95 is an improved version of the earlier Barrett M90. It is a bolt-action rifle in a bullpup design. The major difference between the M95 and the M90 is that the pistol grip and trigger have been moved forward for better magazine clearance. Also, the bolt handle has been redesigned and bent down and to the rear, the barrel chamber has been plated in chrome, and there are also some minor changes to the trigger and firing pin. XM107 In 1999, the M95 won a military competition to become the new XM107. A small number were purchased by the U.S. Army for further testing, but ultimately, the M82 was chosen. The Barrett website also announces that M95 rifle is used for military and law enforcement applications in at least 15 other countries. Users * * - ''Jagdkommando'' special group ...

Barrett M82
The Barrett M82 (standardized by the U.S. military as the M107) is a recoil-operated, semi-automatic anti-materiel rifle developed by the American company Barrett Firearms Manufacturing. Also called the Light Fifty (due to its chambering of the .50 BMG 12.7×99mm NATO cartridge), the weapon is classified in three variants: the original M82A1 (and M82A3) models, the bullpup M82A2 model, and the Barrett M107A1, with an attached muzzle brake (designed to accept a suppressor, and made out of titanium instead of steel). The M82A2 is no longer manufactured, though the XM500 can be seen as its successor. Despite being designated as an anti-materiel rifle, the M82 can also be deployed as an anti-personnel system. Overview Barrett Firearms Manufacturing was founded by Ronnie Barrett for the sole purpose of building semi-automatic rifles chambered for the powerful 12.7×99mm NATO (.50 BMG) ammunition, originally developed for and used in M2 Browning machine guns. The weapon was fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bipod
A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix ''bi-'' and Greek root ''pod'', meaning "two" and "foot" respectively. Bipods are designed to support the weight of the weapon's front portion and barrel, and provide significant stability against unwanted side-to-side movements (i.e. canting) while allowing free movements pivoting around the transverse axis ( pitching). Most modern bipods have foldable and/or telescoping legs, and allow some limited movements around the vertical axis ( panning) and even the longitudinal axis ( tilting). A bipod by itself, with only two supporting legs, is not completely stable and needs to be reinforced by at least one more point of support to be steady, especially against the horizontal shearing force from recoils. This third point of support is typically the buttstock that is firmly pushed/braced against the shooter's body, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Barrel
A gun barrel is a crucial part of gun-type weapons such as 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) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, 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.''A History of Warfare'' - Keegan, John, Vintage 1993. History Gun barrels are usually metal. However, the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sniper Rifle
A sniper rifle is a high-precision, long-range rifle. Requirements include accuracy, reliability, mobility, concealment and optics for anti-personnel, anti-materiel and surveillance uses of the military sniper. The modern sniper rifle is a portable shoulder-fired weapon system with a choice between bolt-action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed 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 was done with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which had shown some weaknesses during the recent Crimean War. At trials in 1857, which tested the accuracy and range of both weapons, Whitworth' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scope Mount
Scope mounts are used to attach telescopic sights or other types of sights to firearms. The scope sight itself is usually made for only one of two main types of mounts, which can be classified as ''scopes for ring mounts'' (for example a 30 mm tube) or ''scopes for rail mounts'' (like for example the Zeiss rail). Words such as ''mounts'' and ''bases'' are used somewhat loosely, and can refer to several different parts which are either used together or in place of each other as ways to mount optical sights to firearms. When it comes to the interface of the firearm itself, the Picatinny rail is one of the most widespread standard for new firearms as of 2020. While most scopes are made for being mounted either with a ''ring mount'' or a ''rail mount'', some sights have an integral mounting mechanism allowing them to be attached directly to the firearm, like for example an integrated Picatinny mount. In addition, there are many proprietary and brand-specific types of mounts that e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
