The Barrett M82 (standardized by the U.S. military as the M107 ) is a recoil-operated , semi-automatic anti-materiel rifle developed by the Australian-owned company Barrett Firearms Manufacturing and produced in the United States.
78-685: The Barrett MRAD (Multi-role Adaptive Design) is a bolt-action sniper rifle designed by Barrett to meet the requirements of the SOCOM PSR . The MRAD is based on the Barrett 98B and includes a number of modifications and improvements. The Barrett MRAD was named the 2012 Rifle of the Year by Shooting Illustrated magazine. After the United States Special Operations Command (USSOCOM) announced their desire for
156-464: A "cock on open" system. Although this bolt system has been rarely used in commercial sporting rifles (the Vostok brand target rifles being the most recognized) and has never been exported outside of Russia, although large numbers of military surplus Mosin–Nagant rifles have been sporterized for use as hunting rifles in the following years since the end of World War II. The Swing was developed in 1970 in
234-632: A US$ 50 million contract for the ASR (Advanced Sniper Rifle) contract, ordering the Barrett MRAD with the ability to convert chambering between 7.62×51mm NATO, .300 Norma Magnum, and .338 Norma Magnum. The MK 22 ASR is issued with Barrett's AML 338 suppressor and paired with the Precision Variable Power Scopes (P-VPS) SU-295/PVS Nightforce ATACR 5-25×56 and SU-295/PVS Nightforce ATACR 7-35×56. MK 22 PSR (Precision Sniper Rifle)
312-555: A bolt-action shotgun, albeit one designed to be attached to an M16 rifle or M4 carbine using an underbarrel mount (although with the standalone kit, the MASS can become a standalone weapon). Mossberg 12-gauge bolt-action shotguns were briefly popular in Australia after the 1997 changes to firearms laws , but the shotguns themselves were awkward to operate and had only a three-round magazine, thus offering no practical or real advantages over
390-453: A carry sling, but according to those who carried it in the field, the M82 is too uncomfortable to be carried on a sling due to its excessive length and weight. It is usually carried in a special carry soft or hard case. The M82A2 differed from M82A1 mostly in its configuration; the pistol grip along with trigger was placed ahead of the magazine, and the buttpad placed below the receiver, just after
468-410: A conventional double-barreled shotgun. Some pistols use a bolt-action system, although this is uncommon, and such examples are typically specialized hunting and target handguns. Most of the bolt-action designs use a rotating bolt (or "turn pull") design, which involves the shooter doing an upward "rotating" movement of the handle to unlock the bolt from the breech and cock the firing pin , followed by
546-475: A firing mechanism without a hammer , but there are some hammer-fired models, such as the Merkel Helix. Firearms using a hammer usually have a comparably longer lock time than hammerless mechanisms. In the sport of biathlon , because shooting speed is an important performance factor and semi-automatic guns are illegal for race use, straight pull actions are quite common and are used almost exclusively in
624-590: A gravity-operated tubular magazine in the stock. Another more well-known bolt-action repeating rifle was the Vetterli rifle of 1867 and the first bolt-action repeating rifle to use centerfire cartridges was the weapon designed by the Viennese gunsmith Ferdinand Fruwirth in 1871. Ultimately, the military turned to bolt-action rifles using a box magazine ; the first of its kind was the M1885 Remington–Lee , but
702-508: A hinge AR-15 to allow for maintenance in the field. With quality .300 Winchester Magnum ammunition the Barrett achieved groups that averaged 0.45 MOA, with the best of them measuring 0.31 MOA. The particular model of the MRAD that was submitted for USSOCOM's MK21 PSR trial was fitted with a 24.5 in (62 cm) barrel, and weighed 14.8 lb (6.7 kg) (without an optic). In 2013,
780-669: A lawsuit brought by the Mexican government in the U.S. District Court for the District of Massachusetts, seeking $ 10 billion in damages. The Mexican government claimed that the Barrett M82 is one of the weapons of choice for drug cartels. According to Romain Le Cour Grandmaison, an expert interviewed by Reuters , the M82 has disrupted the balance of power between criminals and poorly-equipped police forces. The XM107

#1732780076335936-482: A new precision sniper rifle in December 2009, Barrett created the MRAD in accordance with the specifications laid out by SOCOM. Building off of the successful Barrett 98B , the MRAD features multiple improvements such as a folding stock which allows the rifle to be transported more easily. When folded, the stock latches around the bolt handle which increases the security of transporting the rifle without increasing
1014-594: A rearward "pull" to open the breech, extract the spent cartridge case, then reverse the whole process to chamber the next cartridge and relock the breech. There are four major turn bolt-action designs: the Remington M-700 , possibly the single most numerous produced rifle in history which is now also used as basis for most custom competition rifle actions, along with the Mauser system, the Lee–Enfield system, and
1092-478: A rotating bolt design. Johann Nicholas von Dreyse 's rifle of 1838 was accepted into service by Prussia in 1841, which was in turn developed into the Prussian Model in 1849. The design was a single shot breech-loader and had the now familiar arm sticking out from the side of the bolt, to turn and open the chamber . The entire reloading sequence was a more complex procedure than later designs, however, as
1170-509: A separate bolthead that rotates with the bolt and the bearing lugs, in contrast to the Mauser system where the bolthead is a non-removable part of the bolt. The Mosin–Nagant is also unlike the Lee–Enfield system where the bolthead remains stationary and the bolt body itself rotates. The Mosin–Nagant bolt is a somewhat complicated affair, but is extremely rugged and durable; like the Mauser, it uses
1248-430: A single lethal shot from a safe distance. Target shooters favour single-shot bolt actions for their simplicity of design, reliability, and accuracy. Bolt-action shotguns are considered a rarity among modern firearms but were formerly a commonly used action for .410 entry-level shotguns, as well as for low-cost 12- gauge shotguns. The M26 Modular Accessory Shotgun System (MASS) is the most recent and advanced example of
1326-539: A specific weapon's type of action. However, both straight pull and rotating bolt rifles are types of bolt-action rifles. Lever-action and pump-action weapons must still operate the bolt, but they are usually grouped separately from bolt-actions that are operated by a handle directly attached to a rotating bolt. Early bolt-action designs, such as the Dreyse needle gun and the Mauser Model 1871 , locked by dropping
1404-783: A trigger derived from the Finnish Mantari, the Swing was commercially successful, with the basic design reused in the Paramount, RPA Quadlock and Millenium rifles. The Vetterli rifle was the first bolt-action repeating rifle introduced by an army. It was used by the Swiss army from 1869 to circa 1890. Modified Vetterlis were also used by the Italian Army . Another notable design is the Norwegian Krag–Jørgensen , which
1482-595: Is fluted to improve heat dissipation and save weight, and fitted with a large and effective reactive muzzle brake. The muzzle brakes on the earlier models had a round cross-section; later M82 rifles are equipped with two-chamber brakes of rectangular cross-section. M82A1 rifles are fitted with scope mount and folding backup iron sights, should the glass scope break. The U.S. military M82 rifles are often equipped with Leupold Mark 4 telescopic sights. The M82A1M (USMC M82A3) rifles have long Picatinny accessory rails mounted and US Optics telescopic sights . Every M82 rifle
1560-579: Is a type of manual firearm action that is operated by directly manipulating the bolt via a bolt handle , most commonly placed on the right-hand side of the firearm (as most users are right-handed ). The majority of bolt-action firearms are rifles , but there are also some variants of shotguns and handguns that are bolt-action. Bolt-action firearms are generally repeating firearms , but many single-shot designs are available particularly in shooting sports where single-shot firearms are mandated, such as most Olympic and ISSF rifle disciplines. From
1638-555: Is equipped with a folding carrying handle and a folding bipod (both are detachable on the M82A3). The M82A3 is also fitted with a detachable rear monopod under the butt. The buttpad is fitted with a soft recoil pad to further decrease the felt recoil. M82A1 and M82A3 rifles could be mounted on the M3 or M122 infantry tripods (originally intended for machine guns ) or on vehicles using the special Barrett soft-mount. The M82A1 can be fitted with

#17327800763351716-525: Is that it is usually loaded by hand, one round at a time, although a box-like device was made that could drop five rounds into the magazine, all at once via a stripper or en bloc clip. This made it slower to reload than other designs which used stripper or en bloc clips. Another historically important bolt-action system was the Gras system, used on the French Mle 1874 Gras rifle , Mle 1886 Lebel rifle (which
1794-413: Is the straight-pull mechanism, where no upward handle-turning is needed and the bolt unlocks automatically when the handle is pulled rearwards by the user's hand. The first bolt-action rifle was produced in 1824 by Johann Nikolaus von Dreyse , following work on breechloading rifles that dated to the 18th century. Von Dreyse would perfect his Nadelgewehr (Needle Rifle) by 1836, and it was adopted by
1872-589: Is the designation for the Barrett MRAD variant ordered by the US Army. In 2021, the US Army awarded Barrett a US$ 49.9 million contract for delivery of 2,800 MK22 PSR rifles, while the Marine Corps planned to order 250. The MK 22 PSR will have conversion kits for .338 Norma Magnum, .300 Norma Magnum, and 7.62×51mm NATO. However, unlike the MK 22 ASR, it is issued with a Leupold Mark 5HD 5-25x56mm scope. The Army plans for
1950-487: Is the most common bolt-action system in the world, being in use in nearly all modern hunting rifles and the majority of military bolt-action rifles until the middle of the 20th century. The Mauser system is stronger than that of the Lee–Enfield system, due to two locking lugs just behind the bolt head, which make it better able to handle higher-pressure cartridges (i.e. magnum cartridges ). The 9.3×64mm Brenneke and 8×68mm S magnum rifle cartridge "families" were designed for
2028-529: The Biathlon World Cup . The first company to make the straight pull action for .22 caliber was J. G. Anschütz ; Peter Fortner junior designed the "Fortner Action", which was incorporated into the Anschütz 1827 Fortner . The Fortner action is specifically the straight-pull ball bearing lock action, which features spring-loaded ball bearings on the side of the bolt which lock into a groove inside
2106-563: The Mosin–Nagant system. All four differ in the way the bolt fits into the receiver, how the bolt rotates as it is being operated, the number of locking lugs holding the bolt in place as the gun is fired, and whether the action is cocked on the opening of the bolt (as in both the Mauser system and the Mosin Nagant system) or the closing of the bolt (as in the Lee–Enfield system). The vast majority of modern bolt-action rifles were made for
2184-584: The Prussian Army in 1841. While it saw limited service in the German Revolutions of 1848 , it was not fielded widely until the 1864 victory over Denmark . In 1850 a metallic centerfire bolt-action breechloader was patented by Béatus Beringer. In 1852 another metallic centerfire bolt-action breechloader was patented by Joseph Needham and improved upon in 1862 with another patent. Two different systems for primers –the mechanism to ignite
2262-659: The Remington Modular Sniper Rifle was selected as the winner of the PSR competition. However, in 2018, it was decided that the MK21 did not conform to SOCOM requirements at the time, and the program was re-competed as the MK22 ASR (Advanced Sniper Rifle). MK 22 MOD 0 ASR (Advanced Sniper Rifle) is the designation for the Barrett MRAD variant ordered by USSOCOM. In 2019, USSOCCOM awarded Barrett Manufacturing
2340-877: The United States Marine Corps , and orders from the Army and Air Force soon followed. The M82A1 is known by the U.S. military as the SASR—" Special Applications Scoped Rifle ", and it was and still is used as an anti-materiel rifle and explosive ordnance disposal tool. In 2006, Barrett completed development of the XM500 , which has a bullpup configuration similar to the M82A2. Barrett M82 rifles were bought by various military and police forces from at least 30 countries, such as Belgium, Chile, Denmark, Finland, France, Germany, Greece, Indonesia, Italy, Jamaica, Mexico,
2418-498: 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.

In 1993, the German Blaser company introduced the Blaser R93 , a new straight pull action where locking is achieved by a series of concentric "claws" that protrude/retract from the bolthead, a design that is referred to as Radialbundverschluss ("radial connection"). As of 2017 the Rifle Shooter magazine listed its successor Blaser R8 as one of the three most popular straight pull rifles together with Merkel Helix and Browning Maral. Some other notable modern straight pull rifles are made by Beretta , C.G. Haenel , Chapuis , Heym , Lynx , Rößler , Savage Arms , Strasser, and Steel Action. Most straight bolt rifles have

When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber , and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. A less common bolt-action type

The IRA snipers killed five soldiers and a constable with .50 rifles from 1992 to 1997. The snipers usually fired on their targets from a distance of less than 300 metres (980 ft), despite the 1,800 m (5,900 ft) effective range of the weapons.

The U.S. Army and Marine Corps plan to field another Barrett rifle, the Mk22 MRAD , in 2021 to replace the M107. The Mk22 is a bolt-action multi-caliber rifle that is powerful enough to replace the M107 when chambered in .338 Norma Magnum . The M82 is a short-recoil semi-automatic firearm. When the gun is fired,

Fifty-caliber (and larger) rounds have the potential to travel great distances if fired in an artillery -like fashion (with a high angle, which creates an indirect-fire situation), necessitating the observance of extensive safety margins when firing on a range. On February 26, 2016, the U.S. state of Tennessee named

A novel safety feature was the introduction of a third locking lug present at the rear of the bolt that normally did not lock the bolt, since it would introduce asymmetrical locking forces. The Mauser system features "cock on opening", meaning the upward rotation of the bolt when the rifle is opened cocks the action. A drawback of the Mauser M 98 system is that it cannot be cheaply mass-produced very easily. Many Mauser M 98-inspired derivatives feature technical alterations, such as omitting

Supplied with Schultz & Larsen barrels and
3432-409: The barrel initially recoils for a short distance (about 1 inch (25 mm)), while being securely locked by the rotating bolt. After the short travel, the lower part of the accelerator arm, held by the receiver upper part, is already hinged in the bolt carrier and the middle portion strikes it back to the barrel by a rod placed in the bolt carrier, transferring part of the recoil energy of the barrel to
3510-472: The bolt ahead of the lugs may flex on firing which, although a safety advantage with repeated firing over time, this may lead to a stretched receiver and excessive headspacing, which if perceived as a problem can be remedied by changing the removable bolt head to a larger sized one (the Lee–Enfield bolt manufacture involved a mass production method where at final assembly the bolt body was fitted with one of three standard size bolt heads for correct headspace ). In

The most common locking method is a rotating bolt with two lugs on the bolt head, which was used by the Lebel Model 1886 rifle , Model 1888 Commission Rifle , Mauser M 98 , Mosin–Nagant and most bolt-action rifles. The Lee–Enfield has a lug and guide rib, which lock on the rear end of
3744-407: The bolt in addition to the linear motions to perform chambering and primary extraction . The bolt locking of a straight pull action is achieved differently without needing manual inputs, therefore the entire operating cycle needs the shooter to perform only two movements (pull back and push forward), instead of four movements (rotate up, pull back, push forward, and rotate down), this greatly increases
3822-432: The bolt in place. The operation can be done via a rotating bolt , a lever, cam action, a locking piece, or a number of systems. Straight pull designs have seen a great deal of use, though manual turn bolt designs are what is most commonly thought of in reference to a bolt-action design due to the type ubiquity. As a result, the bolt-action term is often reserved for more modern types of rotating bolt designs when talking about
3900-409: The bolt into the receiver. The bolt knob is the part of the bolt handle that the user grips when loading and reloading the firearm and thereby acts as a cocking handle . On many older firearms, the bolt knob is welded to the bolt handle, and as such becoming an integral part of the bolt handle itself. On many newer firearms, the bolt knob is instead threaded onto the handle, allowing the user to change
3978-414: The bolt to achieve reliable cycling and unlock it from the barrel. The bolt is unlocked by turning in the curved cam track in the bolt carrier. Then the barrel is stopped by the combined effect of the accelerator, buffer spring, and the muzzle brake and the bolt continues back, to extract and eject a spent case. On its return stroke, the bolt strips the fresh cartridge from the box magazine and feeds it into

#17327800763354056-420: The bolt's housing. With the new design came a new dry fire method; instead of the bolt being turned up slightly, the action is locked back to catch the firing pin. The action was later used in the centre-fire Heym SR 30 . Typically, the bolt consists of a tube of metal inside of which the firing mechanism is housed, and which has at the front or rear of the tube several metal knobs, or "lugs", which serve to lock

The gun is fed from a large, detachable box magazine holding up to ten rounds, although a rare twelve-round magazine was developed for use during Operation Desert Storm in 1991. The receiver is made from two parts (upper and lower), stamped from sheet steel and connected by cross-pins. The heavy barrel

The Mauser bolt-action system is based on 19th-century Mauser bolt-action rifle designs and was finalized in the Gewehr 98 designed by Paul Mauser . It
4290-413: The design's inherent potential for superior accuracy and precision , as well as ruggedness and reliability compared to self-loading designs. Most bolt-action firearms use a rotating bolt operation, where the handle must first be rotated upward to unlock the bolt from the receiver , then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks
4368-451: The existing bolt handle. These are often made of either rubber or plastic. Most bolt-action firearms are fed by an internal magazine loaded by hand, by en bloc , or by stripper clips , though a number of designs have had a detachable magazine or independent magazine, or even no magazine at all, thus requiring that each round be independently loaded. Generally, the magazine capacity is limited to between two and ten rounds, as it can permit
4446-414: The faster rate of fire that all semi-automatic rifle alternatives allow. There are, however, many semi-automatic rifle designs used especially in the designated marksman role. Today, bolt-action rifles are chiefly used as hunting and target rifles. These rifles can be used to hunt anything from vermin to deer and to large game , especially big game caught on a safari , as they are adequate to deliver
4524-478: The first to be generally adopted was the British 1888 Lee–Metford . World War I marked the height of the bolt-action rifle's use, with all of the nations in that war fielding troops armed with various bolt-action designs. During the buildup prior to World War II , the military bolt-action rifle began to be superseded by semi-automatic rifles and later fully automatic rifles , though bolt-action rifles remained
4602-711: The late 19th century all the way through both World Wars , bolt-action rifles were the standard infantry service weapons for most of the world's military forces, with the exception of the United States Armed Forces , who used the M1 Garand Semi-automatic rifle . In modern military and law enforcement after the Second World War, bolt-action firearms have been largely replaced by semi-automatic and selective-fire firearms, and have remained only as sniper rifles due to
4680-468: The magazine to be flush with the bottom of the rifle, reduce the weight, or prevent mud and dirt from entering. A number of bolt-actions have a tube magazine , such as along the length of the barrel. In weapons other than large rifles, such as pistols and cannons , there were some manually operated breech-loading weapons. However, the Dreyse Needle fire rifle was the first breech loader to use

The M107's maximum effective range is 1,830 m (2,000 yd), while can hit targets past 2,000 m (2,200 yd). Although being accurate to 2.5 MOA means it would hit within a 25 in (640 mm) area at 1,000 m (1,100 yd). The maximum range of this weapon (specifically

European armies continued to develop bolt-action rifles through the latter half of the 19th century, first adopting tubular magazines as on the Kropatschek rifle and the Lebel rifle . The first bolt-action repeating rifle was patented in Britain in 1855 by an unidentified inventor through the patent agent Auguste Edouard Loradoux Bellford using
4914-845: The original bolt knob for an aftermarket one, either for aesthetical reasons, achieving better grip or similar. The type of threads used vary between firearms. European firearms often use either M6 1 or M8 1.25 threads, for example M6 is used on the SIG Sauer 200 STR , Blaser R93 , Blaser R8 , CZ 457 and Bergara rifles, while M8 is used on the Sako TRG and SIG Sauer 404 . Many American firearms instead use 1/4" 28 TPI (6.35 0.907 mm) or 5/16" 24 TPI (7.9375 1.058 mm) threads. Some other thread types are also used, for example, No. 10 32 TPI (4.826 0.794 mm) as used by Mausingfield. There also exists aftermarket slip-on bolt handle covers which are mounted without having to remove

The bolt-action is still common today among many sniper rifles , as the design has the potential for superior accuracy, reliability, reduced weight, and the ability to control loading over
5070-474: The receiver against large springs with every shot. Additionally, the weapon's weight and large muzzle brake also assist in recoil reduction. Various changes were made to the original M82A1 to create the M107, with new features such as a lengthened accessory rail, rear grip, and monopod socket. The Barrett M107, like previous members of the M82 line, is also referred to as the Barrett "Light Fifty". The designation has in many instances supplanted earlier ones, with

Shorter 2"-4" Picatinny rails sections may be user positioned at 3, 6, and 9 o'clock at several fore/aft positions along the handguard. MRADs are offered in several Cerakote colors. Similar to the M16/AR15, the MRAD upper and lower receivers can be separated by pressing a rear latch assembly under the stock while the front detent pin acts as

The Provisional IRA smuggled a number of M82s into Ireland from the United States in the 1980s, apparently made and sold by a gunsmith and former Barrett Firearms employee in Texas . One of the M82s was shipped from Chicago to Dublin in pieces, where it was re-assembled. The IRA equipped two sniper teams with

5460-433: The third safety locking lug, to simplify production. The controlled-feed on the Mauser M 98 bolt-action system is simple, strong, safe, and well-thought-out design that has inspired other military and sporting rifle designs that became available during the 20th century, including the: Versions of the Mauser action designed prior to the Gewehr 98's introduction, such as that of the Swedish Mauser rifles and carbines, lack

5616-495: The width when it is unfolded. A major MRAD feature (and requirement of the military PSR solicitation) is a field-changeable barrel/caliber capability. Loosening two Torx screws in the receiver allows the removal of the barrel from the front of the receiver/handguard. With only a bolt face change, and in some cases a magazine change, caliber may be changed. The factory headspaced bolt face is provided with each barrel. Barrel/caliber change can occur in less than two minutes. In addition to
5694-406: The years leading up to World War II, the Lee–Enfield bolt system was used in numerous commercial sporting and hunting rifles manufactured by such firms in the United Kingdom as BSA, LSA, and Parker–Hale, as well as by SAF Lithgow in Australia. Vast numbers of ex-military SMLE Mk III rifles were sporterised post WWII to create cheap, effective hunting rifles, and the Lee–Enfield bolt system is used in
5772-508: Was approved for "full materiel release", meaning it was officially adopted as the Long Range Sniper Rifle, Caliber .50, M107. The M107 uses a Leupold 4.5–14×50 Mark 4 scope. The Barrett M107 is a .50 caliber, shoulder-fired, semi-automatic sniper rifle. Like its predecessors, the rifle is said to have manageable recoil for a weapon of its size owing to the barrel assembly that itself absorbs force, moving inward toward
5850-519: Was originally intended to be a bolt-action sniper rifle, and the Barrett M95 was originally selected by the U.S. Army in a competition between such weapons. However, under the trials, the decision was made that the U.S. Army did not, in fact, require such a weapon. Then the Army decided on the Barrett M82, a semi-automatic rifle. In summer 2002, the M82 finally emerged from its Army trial phase and
5928-467: Was the first to introduce ammunition loaded with nitrocellulose-based smokeless powder ), and the Berthier series of rifles. Straight-pull bolt-actions differ from conventional turn-pull bolt-action mechanisms in that the bolt can be cycled back and forward without rotating the handle and thus only a linear motion is required, as opposed to a traditional bolt-action, where the user has to axially rotate
6006-595: Was ultimately considered too complicated for issue to soldiers and was supplanted by the Springfield Model 1861 , a conventional muzzle loading rifle. During the American Civil War, the bolt-action Palmer carbine was patented in 1863, and by 1865, 1000 were purchased for use as cavalry weapons. The French Army adopted its first bolt-action rifle, the Chassepot rifle , in 1866 and followed with
6084-581: Was used by Norway, Denmark, and briefly the United States. It is unusual among bolt-action rifles in that is loaded through a gate on the right side of the receiver, and thus can be reloaded without opening the bolt. The Norwegian and Danish versions of the Krag have two locking lugs, while the American version has only one. In all versions, the bolt handle itself serves as an emergency locking lug. The Krag's major disadvantage compared to other bolt-action designs
