39-454: The M110 Semi Automatic Sniper System ( M110 SASS ) is an American semi-automatic sniper rifle that is chambered for the 7.62×51mm NATO round. It is manufactured by Knight's Armament Company , developed from the Knight's Armament Company SR-25 , and adopted by the U.S. military following the 2005 US Army Semi-Automatic Sniper Rifle (XM110 SASR) competition. The M110 is to be replaced by

78-616: A bayonet and could be loaded with ten rounds, using a stripper clip . However, the SKS was quickly replaced by the AK-47 , produced at around the same time, but with a 30-round magazine, and select fire capability. The SKS was the first widely issued weapon to use the 7.62×39mm cartridge. There are semi-automatic pistols , rifles , and shotguns designed and made as semi-automatic only. Selective-fire firearms are capable of both full automatic and semi-automatic modes. Semi-automatic refers to

117-1058: A closed bolt when semi-automatic is selected. Many jurisdictions regulate some or all semi-automatic firearms differently than other types. Various types of semi-automatic weapons were restricted for civilian use in New Zealand after the 2019 Christchurch mosque shootings , in Australia after the Port Arthur massacre , in Norway after the 2011 Utøya shooting . In the United States, the Federal Assault Weapons Ban prohibited semi-automatic weapons with certain additional characteristics, from 1994 to 2004. As of 2023, several U.S. states still restrict similar types of semi-automatic weapons. Heckler and Koch Too Many Requests If you report this error to

156-560: A complement to the M40A5 . The rifle has ambidextrous features such as a double-sided magazine release, safety selector switch, and bolt catch. The rifle is similar to the SR-25 /Mk 11 Mod 0, but differs significantly in buttstock and rail system design. The SR-25, Mk 11 Mod 0, and M110 are based loosely on the original AR-10 developed by Eugene Stoner but feature additional refinements instituted by KAC to maximize parts commonality with

195-560: A contract with a maximum value of $ 44.5 million as winner of the competition to replace the KAC M110. The weapon selected was not specified, but was likely the H&;K G28 ; H&K is to produce 3,643 rifles. A goal of the effort was to give snipers a weapon that didn't "stick out" as a sniper rifle; with a suppressor, the M110 is 46.5 in (1,180 mm), 13 in (330 mm) longer than

234-410: A firearm that uses the force of recoil or gas to eject the empty case and load a fresh cartridge into the firing chamber for the next shot and which allows repeat shots solely through the action of pulling the trigger. A double-action revolver also requires only a trigger pull for each round that is fired but is not considered semi-automatic since the manual action of pulling the trigger is what advances

273-475: A new design to speeding-up re-armament with existing weapons. The Soviet Union and Nazi Germany would both issue successful self-loading and selective-fire rifles on a large scale during the course of the war, but not in sufficient numbers to replace their standard bolt-action rifles. In 1937, the American M1 Garand was the first semi-automatic rifle to replace its nation's bolt-action rifle as

312-453: A round must first be chambered manually before the weapon can fire. When the trigger is pulled, only the hammer and firing pin move, striking and firing the cartridge. The bolt then recoils far enough rearward to extract and load a new cartridge from the magazine into the firearm's chamber, ready to fire again once the trigger is pulled. An open-bolt mechanism is a common characteristic of fully automatic firearms. With this system, pulling

351-418: A semi-automatic handgun. However, to avoid confusion, the term "automatic rifle" is generally, conventionally, and best restricted to a rifle capable of fully automatic fire. Both uses of the term "automatic" can be found; the exact meaning must be determined from context. The mechanism of semi-automatic (or autoloading) firearms is usually what is known as a closed-bolt firing system. In a closed-bolt system,

390-601: A shorter and lighter version of the M110 with a collapsible stock and removable flash suppressor, giving it an overall length of 36 inches (910 mm) and a weight of 9 pounds (4.1 kg) unloaded. The Army wants a capability to convert 125 rifles per month, with the ability to increase to 325 per month. The Army formally requested proposals for the CSASS in June 2014. On 1 April 2016, the Army announced it had awarded Heckler and Koch

429-565: A suppressor) and will cost about $ 12,000 per rifle. The U.S. Marine Corps was slated to begin receiving the CSASS in May 2018 to replace their M110 rifles. However, as of 2022, all of the M110A1 units delivered were configured as squad designated marksman rifles (SDMR) rather than M110A1 CSASS rifles. The M110A2 is an improved version of the original M110 rifle with M-LOK rails, an improved gas system, new suppressor, and adjustable stock. This fills

468-591: Is a 6.5mm Creedmoor conversion for SOCOM M110 rifles. In October 2019, NSWC Crane ordered KAC's self-termed M110K1 conversion kits to upgrade USSOCOM 's M110s to fire 6.5mm Creedmoor, with 14.5-inch (370 mm) and 22-inch (560 mm) barreled configurations. These conversion kits included complete upper receiver assemblies chambered for 6.5 Creedmoor as well as new muzzle brakes, and B5 Systems collapsible precision buttstocks. New QD suppressors for 6.5 Creedmoor were to be ordered separately. Semi-automatic firearm Ferdinand Ritter von Mannlicher produced

507-436: Is common to refer to such firearms as an "autoloader" in reference to their loading mechanism. The term "automatic pistol" almost exclusively refers to a semi-automatic (i.e. not fully automatic) pistol (fully automatic pistols are usually referred to as machine pistols ). With handguns, the term "automatic" is commonly used to distinguish semi-automatic pistols from revolvers. The term "auto-loader" may also be used to describe

546-544: Is shorter than the original M110 and lighter as well at 10.5 lb (4.8 kg), which is comparable to the M110A1 SDMR's weight of 10.9 lb (4.9 kg) with no attachments save an unloaded magazine. The decreased overall length does not come at the cost of barrel length as the M110A2 still has a 20 in (510 mm) barrel. KAC had a 5 year $ 13 million contract in 2020 to supply the Army with M110 rifles and this

585-538: The AR-15 design, improve weapon reliability, and increase accuracy. The main differences between the Mk 11 and M110 are improvements suggested by a user group meeting between NAVSPECWAR, USASOC and USA in 2007: On June 12, 2008, the M110 was ranked #2 on the U.S. Army's top ten inventions of 2007. According to performance specification (MIL-PRF-32316 (AR) w/AMENDMENT 1, 5 October 2009): 3.4.1.1.1 Accuracy. The distance between

624-504: The M1 Garand being a notable example. Modern service rifles such as the M4 carbine are often selective-fire, capable of semi-automatic and automatic or burst-fire operation. Civilian variants such as the AR-15 are generally semi-automatic only. The first successful design for a semi-automatic rifle is attributed to Austria -born gunsmith Ferdinand Ritter von Mannlicher , who unveiled

663-458: The M4 carbine and 7 in (180 mm) longer than the M16A4 rifle . A minimum of 30 CSASS units will be used for production qualification testing and operational testing over 24 months. H&K later confirmed that a modified G28 had indeed been selected as the CSASS rifle. The G28 is nearly 6 cm (2.5 in) shorter and 1.3 kg (3 lb) lighter than the M110 (unloaded and without

702-589: The Mosin-Nagant as their standard service rifle), as well as the German Gewehr 43 , were semi-automatic gas-operated rifles issued during World War II . In practice, they did not replace the bolt-action rifle as a standard infantry weapon. Another gas-operated semi-automatic rifle developed toward the end of World War II was the SKS . Designed by Sergei Gavrilovich Simonov in 1945, it came equipped with

741-629: The United States Army . However, the U.S. Army still acquired M24s from Remington until February 2010.On September 28, 2005, the Knight's Armament Co. rifle won the competition and was selected to be the supplier of the M110 Semi-Automatic Sniper System. The XM110 underwent final operational testing in May and June of 2007 at Fort Drum, New York by a mix of Special Forces troops and Sniper trained soldiers from

780-515: The 10th Mountain Division. In April 2008, U.S. Army soldiers from Task Force Fury in Afghanistan were the first in a combat zone to receive the M110. The troops rated the weapon very highly, noting the quality of the weapon and its semi-automatic capabilities compared to the bolt-action M24. The United States Marine Corps will also be adopting the M110 to replace some M39 and all Mk 11 as

819-660: The Auto-5 ended in 1998. In 1903 and 1905, the Winchester Repeating Arms Company introduced the first semi-automatic rimfire and centerfire rifles designed especially for the civilian market. The Winchester Model 1903 and Winchester Model 1905 operated on the principle of blowback in order to function semi-automatically. Designed entirely by T. C. Johnson , the Model 1903 achieved commercial success and continued to be manufactured until 1932 when

858-652: The M1894 by a stripper clip . In 1902, American gunsmith John Moses Browning developed the first successful semi-automatic shotgun , the Browning Auto-5 , which was first manufactured by Fabrique Nationale de Herstal and sold in America under the Browning name. The Auto-5 relied on long recoil operation ; this design remained the dominant form in semi-automatic shotguns for approximately 50 years. Production of

897-617: The Models of 1905 and 1907 saw limited military and police use. In 1906, Remington Arms introduced the Remington Auto-loading Repeating Rifle . Remington advertised this rifle, renamed the "Model 8" in 1911, as a sporting rifle. This is a locked-breech, long recoil action designed by John Browning . The rifle was offered in .25, .30, .32, and .35 caliber models, and gained popularity among civilians as well as some law enforcement officials who appreciated

936-589: The Winchester Model 63 replaced it. By the early 20th century, several manufacturers had introduced semi-automatic .22 sporting rifles, including Winchester , Remington , Fabrique Nationale and Savage Arms , all using the direct blow-back system of operation. Winchester introduced a medium caliber semi-automatic sporting rifle, the Model 1907 as an upgrade to the Model 1905, utilizing a blowback system of operation, in calibers such as .351 Winchester . Both

975-516: The combination of a semi-automatic action and relatively powerful rifle cartridges. The Model 81 superseded the Model 8 in 1936 and was offered in .300 Savage as well as the original Remington calibers. The first semi-automatic rifle adopted and widely issued by a major military power ( France ) was the Fusil Automatique Modele 1917 . This is a locked-breech, gas-operated action that is very similar in its mechanical principles to

1014-436: The cylinder, not the energy of the preceding shot. The usage of the term automatic may vary according to context. Gun specialists point out that the word automatic is sometimes misunderstood to mean fully automatic fire when used to refer to a self-loading, semi-automatic firearm not capable of fully automatic fire. In this case, automatic refers to the loading mechanism, not the firing capability. To avoid confusion, it

1053-477: The design in 1885. The Model 85 was followed by the equally innovative Mannlicher Models 91, 93 and 95 semi-automatic rifles. Although Mannlicher earned his reputation with his bolt-action rifle designs, he also produced a few semi-automatic pistols, including the Steyr Mannlicher M1894 , which employed an unusual blow-forward action and held five rounds of 6.5mm ammunition that were fed into

1092-488: The first successful design for a semi-automatic rifle in 1885, and by the early 20th century, many manufacturers had introduced semi-automatic shotguns , rifles and pistols . In military use, the semi-automatic M1911 handgun was adopted by the United States Army in 1911, and subsequently by many other nations. Semi-automatic rifles did not see widespread military adoption until just prior to World War II ,

1131-538: The future M1 Garand in the United States. The M1917 was fielded during the latter stages of World War I but it did not receive a favorable reception. However, its shortened and improved version, the Model 1918, was much more favourably received during the Moroccan Rif War from 1920 to 1926. The Lebel bolt-action rifle remained the standard French infantry rifle until replaced in 1936 by the MAS-36 despite

1170-456: The gap of semi-automatic sniper rifles as most all of the M110A1 rifles issued were the SDMR variant and not designed for sniper work. The M110A2 was first seen at AUSA 2021 where it was displayed alongside a 14.5" SOCOM M110 rechambered for 6.5 Creedmoor. The M110A2 was later seen at the 2022 Best Ranger Competition being used by a Ranger-qualified 101st Airborne Division soldier. The M110A2

1209-629: The lighter and more compact M110A1 CSASS , which is developed from the G28, a variant of the Heckler & Koch HK417 ; however, most M110A1 models fielded have been of the SDMR variant. In 2021, a newer variant, the M110A2, was showcased and seen in use in early 2022. The M110 Semi-Automatic Sniper System is intended to replace the M24 Sniper Weapon System used by snipers , spotters , designated marksmen , or squad advanced marksmen in

1248-596: The list of NRA-legal US service rifles under rule 3.1.6 of the NRA High Power Rifle Rules. In April 2011, according to Military.com , the U.S. Army issued a request to the private sector to reconfigure or replace the current Knight Armament M110 sniper rifle, alleging that the current version of the M110 was not functioning well in the field and, according to industry officials and users in the field, required significant maintenance and replacement of parts. The U.S. Army responded directly, claiming that

The average mean radius (AMR) (see 6.11), of each shot group shall be not greater than to 0.68 inches at 300 feet. All targets shall be fired on using M118LR ammunition or equivalent, using five (5) round groups. In 2009, the M110 rifle and commercial equivalents were added to

1326-519: The rifle was functioning perfectly, citing a 100% approval rating from the 173rd Airborne Brigade , and they were simply looking for a smaller, lighter version of M110 for the spotter in a sniper team. The specifications the U.S. Army has issued are as follows: In July 2012, the U.S. Army requested sources to remanufacture the current M110 rifle into the Compact Semi-Automatic Sniper System (CSASS). The CSASS will be

1365-716: The standard-issue infantry weapon. The gas-operated M1 Garand was developed by Canadian-born John Garand for the U.S. government at the Springfield Armory in Springfield, Massachusetts . After years of research and testing, the first production model of the M1 Garand was unveiled in 1937. During World War II , the M1 Garand gave American infantrymen an advantage over their opponents, most of whom were issued slower firing bolt-action rifles. The Soviet AVS-36 , SVT-38 and SVT-40 (originally intended to replace

1404-430: The trigger releases the bolt from a cocked, rearward position, pushing a cartridge from the magazine into the chamber, firing the gun. The bolt retracts to the rearward position, ready to strip the next cartridge from the magazine. The open-bolt system is often used in submachine guns and other weapons with a high rate of fire. It is rarely used in semi-automatic-only firearms, which can fire only one shot with each pull of

1443-465: The trigger. The closed-bolt system is generally more accurate, as the centre of gravity changes relatively little at the moment the trigger is pulled. With fully automatic weapons, the open-bolt operation allows air to circulate, cooling the barrel. With semi-automatic firearms, the closed-bolt operation is preferred, as overheating is not as critical, and accuracy is preferred. Some select-fire military weapons use an open bolt in fully automatic mode and

1482-558: The various semi-automatic rifles designed between 1918 and 1935. Other nations experimented with self-loading rifles between the two World Wars, including the United Kingdom , which had intended to replace the bolt-action Lee–Enfield with a self-loader, possibly chambered for sub-caliber ammunition, but discarded that plan as the imminence of the Second World War and the emphasis shifted from replacing every rifle with

1521-526: Was amended in 2022 to include the M110A2 version of the rifle. The Navy and Marine Corps, which had previously been interested in the M110A1 CSASS, decided to instead pursue an M110 SASS PIP (Product Improvement Program) for FY2021 based on findings indicating improved range and lethality with the PIP compared to the M110A1 CSASS. Funding for subsequent fiscal years has been devoted to this PIP. The M110A3
