Gas-operation is a system of operation used to provide energy to operate locked breech , autoloading firearms . In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber . Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle . This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action , extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action.
104-568: The FN SCAR (Special Operations Forces Combat Assault Rifle) is a family of gas-operated short-stroke gas piston automatic rifles developed by Belgian manufacturer FN Herstal (FN) in 2004. It is constructed with modularity for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consists of two main types. The SCAR-L, for "light",
208-545: A French patent and submitted prototypes for testing by the French army in 1888 although the true date of their invention is uncertain. They would also produce a semi-automatic shotgun in the early 1890s. In 1889, the Austro-Hungarian Adolf Odkolek von Újezd filed a patent for the first successful gas-operated machine gun. Most current gas systems employ some type of piston. The face of the piston

In 1716, he led an exploratory expedition westward over the Blue Ridge Mountains . As interest in the frontier grew, the colonial assembly formed Spotsylvania County in 1720, named after Royal Lieutenant Governor Alexander Spotswood . In 1728, Fredericksburg

Near the historic district is the Lewis Plantation, later named Kenmore, the plantation home of George Washington's sister Betty and her husband, Fielding Lewis . Civil War battles are commemorated in Fredericksburg and Spotsylvania National Military Park . Formed by an act of Congress in 1927,
520-404: A firearm unless it is regulated somehow. Most gas-operated firearms rely on tuning the gas port size, mass of operating parts, and spring pressures to function. Several other methods are employed to regulate the energy. The M1 carbine incorporates a very short piston, or "tappet." This movement is closely restricted by a shoulder recess. This mechanism inherently limits the amount of gas taken from
624-486: A folding or a non-folding precision stock. The SCAR has two receivers: The lower is constructed of polymer, and the upper receiver is one piece and constructed of aluminum. The SCAR features an integral, uninterrupted Picatinny rail on the top of the aluminium receiver, two removable side rails and a bottom one that can mount any MIL-STD-1913 compliant accessories. The lower receiver is designed with an M16 compatible pistol grip, flared magazine well, and raised area around
728-622: A full power cartridge. The direct impingement (DI) method of operation vents gas from partway down the barrel through a tube to the working parts of a rifle where they directly impinge on the bolt carrier. This results in a simpler, lighter mechanism. Firearms that use this system include the French MAS-40 from 1940, the Swedish Ag m/42 from 1942. The Stoner gas system of the American M16 , M4, and AR-15 style rifles utilize
832-639: A future replacement for the M4 carbine . The SCAR was one of the competing weapons in the Individual Carbine competition which aimed to find a replacement for the M4 carbine . A variant of the SCAR was entered into the competition, known as the FNAC ( FN Advanced Carbine ). The weapon is similar to the SCAR Mk 16 Mod 0 but with modifications including a 140 g (0.3 lb) weight reduction resulting in
936-492: A gas piston-operated rifle and pistol which he claimed could be used with sliding, rotating or falling bolts. He would also patent a gas-operated revolver in 1886. Paulson did construct models of his rifle and tried them in France shortly after filing his patent. Furthermore, according to A. W. F. Taylerson, a firearms historian, his patented revolver was probably workable. In 1887, an American inventor called Henry Pitcher patented
1040-548: A gas-operated conversion system that he claimed could be applied to any manually-operated magazine rifle. In 1890 he would patent and submit an original gas-operated rifle for testing by the US government but it performed poorly and was ultimately never adopted despite being offered commercially for the civilian market. In the 1880s a gas piston-operated rifle and pistol were developed by the Clair Brothers of France who received
1144-428: A gas-operated repeating rifle but subsequently failed to develop that idea further. Between 1883 and 1885, Hiram Maxim filed several patents on blowback-, recoil-, and gas-operation. In 1885, one year after Maxim's first gas-operated patent, a British inventor called Richard Paulson, who a year before had patented a straight blowback-operated rifle and pistol, again, one year after Maxim’s first blowback patent, patented

#17327654726611248-467: A hole being drilled in the barrel. Both governments would first adopt weapons and later abandon the concept. Most earlier US M1 Garand rifles were retrofitted with long-stroke gas pistons, making the surviving gas trap rifles valuable in the collector's market. In the 1980s Soviet designer Alexander Adov from TsKIB SOO modified the concept with a tube diverting gas from the muzzle to a standard long stroke system (see below) in order to diminish influence of
1352-511: A left-handed operator to load under fire. The standalone stock assembly has the FN40GL mounted to the bottom rail as with the rifle, but still has 3 o'clock, 6 o'clock, and 9 o'clock rail positions for other accessories. This is mainly during non-lethal uses for other mounted additions like LED lights and laser dazzlers . The trigger is placed lower than normal for operation with the user's middle finger while keeping their trigger finger free to use

The competition was cancelled before a winner was chosen. In 2008, a variant of the FN SCAR—the Heat Adaptive Modular Rifle (HAMR)—was one of four finalist rifles for
1560-422: A modified version of this where a gas tube delivers gas into the bolt carrier to impinge on the bolt, which acts as a piston to cycle the rifle. One principal advantage is that the moving parts are placed in-line with the bore axis meaning that sight picture is not disturbed as much. This offers a particular advantage for fully automatic mechanisms. It has the disadvantage of the high-temperature propellant gas (and

Early guns, such as Browning's "flapper" prototype, the Bang rifle , and the Garand rifle , used relatively low-pressure gas from at or near the muzzle . This, combined with larger operating parts, reduced the strain on the mechanism. To simplify and lighten the firearm, gas from nearer the chamber needed to be used. This high- pressure gas has sufficient force to destroy

Both types are available in Close Quarters Combat ( CQC ), Standard ( STD ), and Long Barrel ( LB ) variants. In early 2004, United States Special Operations Command (USSOCOM) issued a solicitation for a family of Special Operations Forces Combat Assault Rifles, the so-called SCAR, designed around two different calibers but featuring high commonality of parts and identical ergonomics. The SCAR system completed low rate initial production testing in June 2007. After some delays,

The FN40GL is attached to SCAR rifles on the bottom rail with a trigger adapter and dual locking clamp levers on the launcher, limiting the ability to integrate with other rifles. Barrel length is 240 mm (9.6 in), and is unique in that it is the only system where the barrel can swivel to the left or right for loading, while other breech-loading launchers pivot specifically to one side. This enhances its ambidexterity, making it easy for

In either case, the energy is imparted in a short, abrupt push and the motion of the gas piston is then arrested, allowing the bolt carrier assembly to continue through the operating cycle through kinetic energy . This has the advantage of reducing the total mass of recoiling parts compared with a long-stroke piston. This, in turn, enables better control of the weapon due to less mass needing to be stopped at either end of

7176-483: The bolt carrier travel and prevents hot combustion gases from being pushed into the internals and removes powder residue in the receiver which significantly improves reliability, increasing the lifespan of weapon parts by reducing instances of malfunctions under prolonged periods of extreme high rate of fire and suppressed shooting. The short-stroke operating system is available both on military ( HK416 lineage , LMT MARS ) and civilian markets as an alternative or retrofit to
7280-431: The carbines in an "extreme dust environment". The purpose of the shoot-off was to assess future needs, not to select a replacement for the M4. During the test, the SCAR suffered 226 stoppages. Since a percentage of each weapons' stoppages were caused by magazine failures, the FN SCAR, XM8 and HK416 performed statistically similarly. The FN SCAR ranked second to the XM8 with 127 stoppages, but with fewer stoppages compared to
7384-433: The city is $ 43,063. 18% of the population is below the poverty line . The Fredericksburg Police Department tracks crime information under the state-level system of the Uniform Crime Reporting program. Per state code, the central repository for crime statistics rests with the Department of State Police, which compiles data from all of the participating agencies into an annual publication Archived November 25, 2011, at
7488-641: The city, and his sister Betty lived at Kenmore , a plantation house then outside the city. Several citizens played active roles during the American Revolution (1763–1781). For example, a number of locals signed the Leedstown Resolves, which formed an association to protest the Stamp Act in the 1760s. In the 1770s, Fielding Lewis , owner of Kenmore Plantation and brother-in-law to George Washington , also operated an arms factory for
7592-508: The city. The population density was 1,833 inhabitants per square mile (708/km ). There were 8,888 housing units at an average density of 845 per square mile (326/km ). The racial makeup of the city was 54% White , 21% Black or African American , 0.31% Native American , 4.74 Asian , 0.067 Pacific Islander , 2.56% from other races , and 1.95% from two or more races.12% of the population were Hispanic or Latino of any race. There were 8,102 households, out of which 21.6% had children under
7696-547: The college changed its name from Mary Washington College to the University of Mary Washington. Two additional campuses for graduate and professional studies and education and research are located in Stafford County and in King George County , respectively. Musician Link Wray invented the power chord of modern rock guitar in Fredericksburg in 1958 during an improvisation of the instrumental piece "Rumble" ,
7800-578: The development of a canal on the Rappahannock and construction of a turnpike and plank road to bind the interior country to the market town. By 1837, a north–south railroad, which became the Richmond, Fredericksburg and Potomac Railroad , linked the town to Richmond, the state capital. A much-needed railroad joining the town to the West's arming region was not finished until after the Civil War. During
7904-406: The energy to motion that, in turn, cycles the action of the firearm. As the resulting motion is forward toward the muzzle of the gun, some sort of mechanical system is needed to translate this into the rearward motion needed to operate the bolt. This adds to the complexity of the mechanism and its weight, and the placement of the trap generally results in a longer weapon and allows dirt to easily enter
8008-516: The first rifles began to be issued to operational units in April 2009, and a battalion of the U.S. 75th Ranger Regiment was the first large unit deployed into combat with 600 of the rifles in 2009. The U.S. Special Operations Command later cancelled their purchase of the SCAR-L and planned to remove the rifle from their inventory by 2013. However, they will continue to purchase the SCAR-H version, and also plan to purchase 5.56 mm conversion kits for
8112-438: The front of the floating chamber. The .22 caliber Colt Service Ace conversion kit for the .45 caliber M1911 pistol also used Williams' system, which allows a much heavier slide than other conversions operating on the unaugmented blowback mechanism and makes training with the converted pistol realistic. A floating chamber provides additional force to operate the heavier slide, providing a felt recoil level similar to that of
8216-530: The gas engine on barrel and increase accuracy, but his sniper rifle wasn't adopted due to the dissolution of the Soviet Union . With a long-stroke system, the piston is mechanically fixed to the bolt group and moves through the entire operating cycle. This system is used in weapons such as the Bren light machine gun , AK-47 , Tavor , FN Minimi , FN MAG , FN FNC , and M1 Garand . The primary advantage of
8320-552: The long-stroke gas piston system used on the M1 Garand the piston assembly is integrated with the operating rod and moves with the bolt group. The caveat of this system is that it has heavier moving mass than modern long-stroke gas piston systems used on rifles like the AK-47 , Tavor , FN FNC , etc. Hence firearms using this system do have higher felt recoil than their equivalent modern long-stroke gas piston counterparts. The bolt
8424-403: The long-stroke system is that the mass of the piston rod adds to the momentum of the bolt carrier enabling more positive extraction, ejection, chambering, and locking. The primary disadvantage to this system is the disruption of the point of aim due to several factors such as: the center of mass changing during the action cycle, abrupt stops at the beginning and end of bolt carrier travel, and
8528-698: The magazine and bolt release buttons. The front sight flips down for unobstructed use of optics and accessories. The rifle uses a "tappet" type of closed gas system much like the M1 Carbine while the bolt carrier otherwise resembles the Stoner 63 or Heckler & Koch G36 . The SCAR is built at the FN Manufacturing, LLC plant in Columbia, South Carolina, in the United States. Since 2008, FN Herstal has been offering semi-automatic versions of
8632-400: The mechanism. Despite these disadvantages, they use relatively low pressure gas and do not require a hole in the barrel, which made them attractive in early designs. The system is no longer used in modern weapons. Hiram Maxim patented a muzzle-cup system in 1884 described in U.S. patent 319,596 though it is unknown if this firearm was ever prototyped. John Browning used gas trapped at
8736-617: The muzzle to operate a "flapper" in the earliest prototype gas-operated firearm described in U.S. patent 471,782 , and used a slight variation of this design on the M1895 Colt–Browning machine gun "potato digger". The Danish Bang rifle used a muzzle cup blown forward by muzzle gas to operate the action through transfer bars and leverage. Other gas-trap rifles were early production M1 Garands and German Gewehr 41 (both Walther and Mauser models). The American and German governments both had requirements that their guns operated without
8840-522: The national military park preserves portions of the battlefields of Fredericksburg , Chancellorsville , the Wilderness , and Spotsylvania Court House . The Fredericksburg National Cemetery , also part of the park, was developed by the federal government after the war on Marye's Heights on the Fredericksburg battlefield. It contains more than 15,000 Union burials from the area's battlefields. Many unidentified soldiers were buried in mass graves. Among
8944-839: The nearby region have several radio stations, including (on the FM dial) WQIQ (88.3, "Radio IQ", public radio, licensed to nearby Spotsylvania), WLJV (89.5, contemporary Christian), WPER (90.5, Christian), WFLS (93.3, country), WGRQ (95.9, "SuperHits", classic hits, licensed to nearby Fairview Beach), WWUZ (96.9, classic rock, licensed to nearby Bowling Green), WVBX (99.3, contemporary hit radio, licensed to nearby Spotsylvania), WBQB ("B-101.5", adult contemporary) and WGRX ("Thunder 104.5", country, licensed to nearby Falmouth). Fredericksburg AM stations include WFVA (1230, news and talk) and WNTX (1350, talk, news, and sports). WGRQ and WGRX are owned locally by Telemedia Broadcasting. WFLS, WWUZ, WVBX, and WNTX are owned by Alpha Media . In 2001,
9048-446: The newspaper and associated website were purchased by Berkshire Hathaway 's BH Media Group. Fredericksburg Today , an online hyperlocal news site began operation following the 2014 bankruptcy of The Free Lance–Star . In 2024, Fredericksburg Today was replaced by The Fredericksburg Free Press , a 501(c)(3) nonprofit dedicated to providing impartial and nonpartisan digital news to the Fredericksburg region. Fredericksburg and
9152-437: The north and includes the historic house Belmont, home of American Impressionist artist Gari Melchers . Public parks run by the city include: Central Rappahannock Regional Library The Fredericksburg City Public Schools are run independently of the surrounding counties. The public primary and secondary schools include: Private schools include: The University of Mary Washington , established in 1908 and opened in 1911,
9256-746: The official announcement from SOCOM and they did not reverse their decision. SOCOM decided to procure the 7.62mm Mk 17 rifle, the 40mm Mk 13 grenade launcher, and the 7.62mm Mk 20 Sniper Support Rifle variants of the Special Operations Forces Combat Assault Rifle (SCAR) manufactured by FN. SOCOM would not purchase the 5.56mm Mk 16. At that point the individual service component commands within SOCOM (Army Special Operations Command, Naval Special Warfare Command, Air Force Special Operations Command, and Marine Corps Forces Special Operations Command) would or would not still buy
9360-620: The order for the Mk 16 Mod 0, see below), whereas the Mk 17 (SCAR-H) had been intended to replace the M14 and Mk 11 sniper rifles in use. However, the weapon will only supplement other weapons, while issuance remains of the operator's discretion. The semi-automatic only Mk 20 Mod 0 Sniper Support Rifle (SSR) is based on the SCAR-H. It includes a longer receiver, a beefed-up barrel extension and barrel profile to reduce whip and improve accuracy, and an enhanced modular trigger that can be configured for single-stage or two-stage operation together with either
9464-510: The previous decision and called for a SCAR that could change calibers. The Mk 17 was chosen to be scaled down because it had a larger receiver for the 7.62×51mm round, and so the 5.56mm Mk 16 could not be scaled up to chamber the larger round. The 5.56mm conversion kit was finalized in late 2010 and orders began in mid-2011. On 9 December 2011, the Naval Surface Warfare Center Crane Division released
9568-405: The purchase. Remaining funds would be expended for the SCAR-H and the Mk 20 sniper variant. At the time, SOCOM had bought 850 Mk 16s and 750 Mk 17s. SOCOM had operators turn in their Mk 16s and is not keeping them in the inventory, but started developing a conversion kit for the Mk 17 to make it capable of firing 5.56mm rounds. "FN America believes the issue is not whether the SCAR, and specifically
9672-404: The region left slavery for freedom in 1862 alone, getting behind Union lines. Tourism is a major part of the economy. Approximately 1.5 million people visit the Fredericksburg area annually, including the battlefield park, the downtown visitor center, events, museums, art shops, galleries, and many historical sites. Fredericksburg is home to Central Park (as of 2004, the second-largest mall on
9776-564: The regional economy influenced by the U.S. government . The city also benefited from its relative proximity to four military installations: the United States Marine Corps ' Quantico Base , the U.S. Army 's Fort Belvoir , the U.S. Navy 's Dahlgren Surface Weapons Base , and the Virginia National Guard 's Fort A.P. Hill . The University of Mary Washington was founded in Fredericksburg in 1908 as
9880-568: The rifle. The double-action trigger is long and heavy to prevent easily and unintentionally firing a round under stress. It can fire the Pike 40 mm guided munition. In July 2007, the United States Army announced a limited competition between the M4 carbine , FN SCAR, HK416 , and the previously shelved HK XM8 . Ten examples of each of the four competitors were involved. During the testing, 6,000 rounds apiece were fired from each of
9984-522: The second test resulted in a total of 307 stoppages for the M4 after lubrication was increased, but did not explain why the M4 suffered 882 stoppages with that same level of lubrication in the third test. The SCAR was one of the weapons displayed to U.S. Army officials during an invitation-only Industry Day on 13 November 2008. The goal of the Industry Day was to review current carbine technology for any situation prior to writing formal requirements for
10088-609: The time of European encounter, the indigenous inhabitants of the area that became Fredericksburg were a Siouan -speaking tribe called the Manahoac . English colonists recorded the name of the Manahoac village there as Mahaskahod . Siouan tribes occupied much of the area of the Piedmont. The Tidewater areas of the coastal plain had primarily Algonquian -speaking tribes making up the Powhatan Confederacy . Located on
10192-459: The use of the barrel as a fulcrum to drive the bolt back. Also, due to the greater mass of moving parts, more gas is required to operate the system that, in turn, requires larger operating parts. With a short-stroke or tappet system, the piston moves separately from the bolt group. It may directly push the bolt group parts, as in the M1 carbine , or operate through a connecting rod or assembly, as in
10296-414: The war, Fredericksburg recovered its former position as a center of local trade and slowly grew beyond its prewar boundaries. Neither the city of Fredericksburg nor the surrounding counties reached the 1860 level of population again until well into the 20th century. After the war, many freedmen moved to Richmond and Petersburg , where there had been established free black communities before the war, and there
10400-542: The weapon's barrel heats up during firing. There have been previous firearms with mixed open/closed bolt operation, but the automatic temperature-based operating mode switch is an innovation. The IAR competition was expected to result in Marine Corps procurement of up to 6,500 automatic rifles over five years, but eventually the SCAR variant was passed over in favor of the Heckler and Koch HK416 rifle, later designated as
10504-469: Was declared a port for the county, of which it was then a part. Named for Frederick, Prince of Wales , son of King George II , the colonial town named its streets after the members of the royal family. The county court was moved to Fredericksburg in 1732. Hence, the community served as county seat until 1780. The court was then moved to Spotsylvania Courthouse, Virginia – closer to the geographical center of Spotsylvania County. In 1781, Fredericksburg
10608-486: Was incorporated as a town with its own court, council, and mayor. It received its charter as an independent city in 1879 and under Virginia law, was separated from Spotsylvania County. The city adopted its present city manager/council form of government in 1911. The city has close associations with George Washington , whose family in 1738 moved to Ferry Farm in Stafford County near the Rappahannock River opposite Fredericksburg. Washington's mother, Mary , later moved to
10712-613: Was introduced in 2019. It is a semi-automatic only civilian version of the FN Mk 20 SSR. In 2020 the FN SCAR 20S 6.5CM variant was announced chambered in 6.5mm Creedmoor . This chambering has been selected by USSOCOM for long-range use. Introduced in 2004 as an addition, the Enhanced Grenade Launching Module (EGLM), officially referred to as the FN40GL, or Mk 13 Mod 0, is a 40 mm grenade launcher based on
10816-621: Was more work. In the early 20th century, as the Jim Crow era continued in the South, there was widespread population movement. Many African-Americans left rural areas of the South for work and other opportunities in industrial cities of the North and Midwest in the Great Migration . Some settled in Washington, D.C., where there were more opportunities, or further north. War-related buildup at defense facilities for World War II added to
