The .50 Browning Machine Gun, also known as the .50 BMG, 12.7×99mm NATO, and designated as the 50 Browning by the C.I.P., is a .50 in (12.7 mm) caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces, as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous belt using metallic links.
An anti-personnel weapon is a weapon primarily used to maim or kill infantry and other personnel not behind armor, as opposed to attacking structures or vehicles, or hunting game. The development of defensive fortification and combat vehicles gave rise to weapons designed specifically to attack them, and thus a need to distinguish between those systems and ones intended to attack people. For instance, an anti-personnel landmine will explode into small and sharp splinters that tear flesh but have little effect on metal surfaces, while anti-tank mines have considerably different design, using much more explosive power to effect damage to armored fighting vehicles, or use explosively formed penetrators to punch through armor plating.
A sniper rifle is a high-precision, long-range rifle. Requirements include high accuracy, reliability, and mobility, concealment, and optics, for anti-personnel, 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 action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge.
The M24 Sniper Weapon System (SWS) or M24 is the military and police version of the Remington Model 700 rifle, M24 being the model name assigned by the United States Army after adoption as their standard sniper rifle in 1988. The M24 is referred to as a "weapon system" because it consists of not only a rifle, but also a detachable telescopic sight and other accessories.
A designated marksman (DM), squad advanced marksman (AD) or squad designated marksman (SDM) is a military marksman role in an infantry squad. The term sniper was used in Soviet doctrine although the soldiers using the Dragunov SVD were the first to use a specifically designed designated marksman rifle. The analogous role in the Israel Defense Forces is sharpshooter.
The Heckler & KochG36(Gewehr 36) is a 5.56×45mm NATO assault rifle designed in the early 1990s by German weapons manufacturer Heckler & Koch as a replacement for the heavier 7.62×51mm G3 battle rifle. It was accepted into service with the Bundeswehr in 1997, replacing the G3. Since then, it has also been a popular export, and the G36 has seen active service in military and police units in several countries, including Germany, Spain,Kurdistan Region, and the United Kingdom. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine.
The Accuracy International AWM is a bolt-action sniper rifle manufactured by Accuracy International designed for magnum rifle cartridges. The Accuracy International AWM is also unofficially known as the AWSM, which typically denotes AWM rifles chambered in .338 Lapua Magnum.
The Accuracy International Arctic Warfare rifle is a bolt-action sniper rifle designed and manufactured by the British company Accuracy International. It has proved popular as a civilian, police, and military rifle since its introduction in the 1980s. The rifles have some features that improve performance in very cold conditions without impairing operation in less extreme conditions.
The Barrett M82 is a recoil-operated, semi-automatic anti-materiel rifle developed by the American company Barrett Firearms Manufacturing.
The Mk 14 Enhanced Battle Rifle (EBR) is an American military selective fire battle rifle, and a designated marksman rifle chambered for the 7.62×51mm NATO cartridge. It is a variant of the M14 battle rifle and was originally built for use with units of United States Special Operations Command, such as the United States Navy SEALs, Delta Force, and task specific Green Berets ODA teams/units.
A designated marksman rifle (DMR) is a modern scoped high-precision rifle used by infantry in the designated marksman (DM) role. It generally fills the engagement range gap between a service rifle and a dedicated sniper rifle, at around 300–600 metres (330–660 yd).
The SR-25 is a designated marksman rifle and semi-automatic sniper rifle designed by Eugene Stoner and manufactured by Knight's Armament Company.
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.
The origins of the modern British military rifle are within its predecessor the Brown Bess musket. While a musket was largely inaccurate over 100 yards (91 m), due to a lack of rifling and a generous tolerance to allow for muzzle-loading, it was cheap to produce and could be loaded quickly. The use of volley or mass firing by troops meant that the rate of fire took precedence over accuracy.
The Raufoss Mk 211 is a .50 BMG multi-purpose anti-materiel high-explosive incendiary/armor-piercing ammunition projectile produced by Nammo under the model name NM140 MP. It is commonly referred to as multipurpose or Raufoss, meaning red waterfall in Norwegian. This refers to Nammo's precursor company Raufoss Ammunisjonsfabrikker, an ammunition manufacturer established 1896 in Raufoss, Norway. The "Mk 211" name comes from the nomenclature Mk 211 Mod 0 used by the U.S. military for this round.
The Heckler & Koch HK417 is a battle rifle designed and manufactured by Heckler & Koch.
The AS50 is a semi-automatic .50 BMG anti-materiel precision rifle manufactured by British firearms producer Accuracy International. It enables operators to engage targets at very long range with high accuracy using explosive or incendiary ammunition, and employs a gas operated semi-automatic action and muzzle brake, allowing for lower recoil than the AW50 bolt-action rifle and faster target acquisition. The rifle is highly transportable, ergonomic and lightweight. It can be disassembled in less than three minutes and serviced without tools.
The Precision Sniper Rifle (PSR) was a program by United States Special Operations Command to replace all bolt-action sniper rifles in use by United States special operations snipers with a single bolt-action rifle chambered for a large caliber Magnum chambering like .300 Win Mag, and .338 Lapua Magnum. The solicitation was placed on January 15, 2009. The contract was awarded to Remington Arms for their Modular Sniper Rifle as Mk 21 Precision Sniper Rifle
The M2010 Enhanced Sniper Rifle (ESR), formerly known as the XM2010 and M24 Reconfigured Sniper Weapon System, is a sniper rifle developed by PEO Soldier for the United States Army. It is derived from and replaced the M24 Sniper Weapon System, and was designed to give snipers longer range in the mountainous and desert terrain of the War in Afghanistan. After winning a competitive bidding process, Remington was awarded the production contract for up to 3,600 weapons. The Army had anticipated sending the upgraded weapons to deployed snipers in late 2010, but later expected fielding would happen in January 2011. The M2010 fires .300 Winchester Magnum (7.62×67mm) ammunition, which offers about 50 percent more effective range than the M24's 7.62×51mm NATO. This chambering to dimensionally larger cartridges is possible because the M24 was designed to use the "long action" bolt version of the Remington 700 receiver for cartridges up to 3.34 inches (84.84 mm) in overall length.
The MK 13 rifle is made using the Accuracy International Chassis System (AICS) version 2.0 mated to a long action Remington 700 receiver. The AICS 2.0 folding stock reduces the rifle's overall length by 210 mm (8.3 in) when folded and adds 0.2 kg (0.44 lb) to the rifle's total weight. The rifle has a cheekpiece design that adjusts sideways and for height for optimal cheek position when using night vision equipment or telescopic sights with large objective lenses. There is also a quick-adjust cheek-piece option that has a spring-loaded cheek-piece in conjunction with a quick-adjust butt plate. The side panels are made from a high-strength polymer and are available in the colors olive drab, dark earth or black. Sling attachment points are mounted on each side of the rifle, so it can be carried flat against the back and used comfortably by left- and right-handed users. A front attachment point is situated below the fore-end and can be used to anchor a target-style sling or replaced by an adapter for a Harris bipod.
