39-411: The Remington Model 870 is a pump-action shotgun manufactured by Remington Arms Company, LLC. It is widely used by the public for shooting sports , hunting and self-defense, as well as by law enforcement and military organizations worldwide. The Remington 870 was the fourth major design in a series of Remington pump shotguns. John Pedersen designed the fragile Remington Model 10 (and later

78-400: A lever-action , as it does not require the trigger hand to be removed from the trigger while reloading. Also because the action is cycled in a linear fashion, it creates less torque that can tilt and throw the gun off aim when repeat-firing rapidly. The first slide action patent was issued to Alexander Bain of Britain in 1854. The first pump action firearm with a magazine was technically

117-564: A trigger disconnector , and were capable of firing a new round as fast as the pump action was cycled, with the trigger held down continuously. This technique is called a slamfire , and was often used in conjunction with the M1897 and M1912 shotguns in World War I trench warfare. Modern pump-action designs are a little slower than a semi-automatic shotgun , but the pump-action offers greater flexibility in selection of shotshells , allowing

156-594: A bolt which locks into an extension in the barrel. The action, receiver, fire control group, safety catch and slide release catch of the Remington Model 870 shotgun are similar to those used on the Remington Model 7600 series pump-action centerfire rifles and carbines . The basic fire control group design was first used in the automatic 11–48 . Twelve gauge stocks will also interchange on the older 12-gauge-sized 20-gauge receivers, although modification

195-411: A new scaled-down receiver size, and in 1972, a 20-gauge Lightweight ("LW") version was introduced on the same sized receiver, and all of the smaller gauges today are produced on that size receiver. From the original fifteen models offered, Remington currently produces dozens of models for civilian, law enforcement, and military sales. The maximum shell length that can be used in a Remington 870 depends on

234-529: A similar mechanism to both load a pellet and compress a spring piston for power, or pneumatic guns where a pump is used to compress the air used for power. See the airgun article for information on how spring piston and pneumatic airguns work. The 43mm GM-94 is a pump-action grenade launcher developed by the KBP design bureau for use by Russian special forces . It carries three rounds in an above-the-barrel tubular magazine. Another pump-action grenade launcher

273-417: A sleeve around the grip area of the stock which the shooter would slide back and forward to cycle the gun. This was done because the forend based pump action was under patent at the time. Pump-action shotguns , also called pump shotguns , slide-action repeating shotguns or slide-action shotguns are the most commonly seen pump-action firearms. These shotguns typically use a tubular magazine underneath

312-516: A trigger disconnector, which disconnects the trigger from the sear as the bolt moves back, so that the trigger must be released and pulled again to fire the shotgun after it closes. Many early pump shotguns, such as the Winchester 1897 , did not have trigger disconnectors, and would, if the trigger were held back, fire immediately upon closing. Due to the higher rate of fire that this allows, some shooters prefer models without this feature, such as

351-503: Is a Chinese state-owned defense corporation that manufactures commercial and military products. Norinco Group is one of the world's largest defense contractors. The company's subsidiary, China North Industries Corporation ( Chinese : 中国北方工业有限公司 ), or simply Norinco , markets Norinco Group's products internationally, and is also involved in domestic civil construction and military defense projects. Some of Norinco's international customers include Pakistan , Zimbabwe , and

390-486: Is especially important when hunting, as many locations have legal limits on the magazine capacity: for example, three rounds for shotguns and five rounds for rifles. The BSA Machine Carbine used a unique pump-action that also required twisting the handguard. Another variant was the Burgess Folding Shotgun from the late 19th century where instead of manipulating the forend to cycle the action, it had

429-600: Is important to also check the barrel markings to ensure the chosen cartridge length is safe to use. 870 variants can be grouped into the following: Chinese arms company Norinco has made unlicensed copies of the Remington 870, as the design is no longer under patent protection. The most common of these designs are the Norinco HP9-1 and M-98, the difference being that the HP9-1 has either a 12.5" or 14" barrel, whereas

468-427: Is needed to fit the smaller sized 20-gauge receivers employed since the late 1970s. Several parts of the 870, such as buttstocks and magazine tubes, will interchange with the semi-automatic Remington 1100 and 11–87 . The original 870 models were offered with fixed chokes . In 1986 Remington introduced the new Remington "Rem Choke" system of screw-in chokes (also fitted to Remington model 1100 auto-loading shotguns at

507-576: Is the China Lake grenade launcher , which saw usage by the U.S. Navy SEALS in the Vietnam War in limited numbers. Norinco China North Industries Group Corporation Limited , doing business internationally as Norinco Group (an abbreviation of "North Industries Corporation"), and known within China as China Ordnance Industries Group Corporation Limited ( Chinese : 中国兵器工业集团有限公司 ),

546-614: Is the Krieghoff Semprio "in-line repeating rifle ". The Semprio is a reverse pump-action system that ejects cartridges when the fore-end is pushed forward and loads the chamber when pulled backward. The Semprio's 7-lug bolt head design displays a locking surface of 65 mm (0.101 in ) compared to the 56 mm (0.087 in ) of the Mauser M98 bolt-action rifle . The term pump-action can also be applied to various airsoft guns and air guns , which use

585-414: Is typically fed from a tubular magazine underneath the barrel, which also serves as a guide to the movable forend. The rounds are fed in one by one through a port in the receiver, where they are pushed forward. A latch at the rear of the magazine holds the rounds in place in the magazine until they are needed. If it is desired to load the gun fully, a round may be loaded through the ejection port directly into

624-869: The Democratic Republic of the Congo , where it negotiated arms-for-minerals deals, as well as Venezuela . Established in 1980 with the approval of the State Council of the People's Republic of China , Norinco is an enterprise group engaged in both products and capital operation, integrated with research and development, manufacturing, marketing and services. Norinco mainly deals with defense products, petroleum and mineral resources development, international engineering contracting, optronic products, civilian explosives and chemical products, sporting arms and equipment, vehicles and logistics operation. In 1993,

663-607: The Ithaca 37 , Stevens Model 520/620 , and Winchester Model 12 . When used in rifles , this action is also commonly called a slide action . In the late 19th and early 20th century it was referred to as a trombone action , because it functioned similarly to the musical instrument of the same name. Colt manufactured the Colt Lightning Carbine from 1884 to 1904 chambered in .44-40 caliber. The slide action Winchester Model 1890 chambered in .22 caliber

702-592: The Winchester Model 12 . To achieve better sales, Remington produced the Model 870 in 1950, which was more modern and reliable in its construction, easy to take apart and maintain, and relatively inexpensive. The 870 was a commercial success. Remington sold two million guns by 1973 (ten times the number of Model 31 shotguns it replaced). As of 1983, the 870 held the record for the best-selling shotgun in history, with three million sold. By 1996, spurred by sales of

741-406: The gun barrel to hold the shells , though there are some variants that use a box magazine like most rifles. It's not uncommon to see extra ammunition stored in externally mounted "shell holder" racks (usually as "sidesaddle" on one side of the receiver , or on the buttstock ) for quick on-field reloading. The shells are chambered and extracted by pulling/pushing the sliding fore-end enveloping

780-793: The 1993 ban. In November 2020, Donald Trump issued an executive order prohibiting any American company or individual from owning shares in companies that the United States Department of Defense has listed as having links to the People's Liberation Army , which included Norinco Group. In June 2021, Joe Biden issued Executive Order 14032 expanding the scope of the national emergency declared in order 13959. In March 2023, Politico reported that Norinco shipped assault rifles, drone parts, and body armor to Russia between June and December 2022. Media reports indicate that Hamas has over thousands of Norinco assault rifles used for

819-550: The M-98 has an 18.5" barrel. In the United States, where most Norinco products are specifically non-importable, this shotgun was imported and sold under the names Norinco Hawk 982 and Interstate Hawk 982. (designated pumppuhaulikko 12 HAUL REM 870) Pump action shotgun Because the forend is manipulated usually with the support hand, a pump-action firearm is much faster than a bolt-action and somewhat faster than

858-425: The barrel and receiver of the particular model. While the receiver length determines whether a shell will feed, the chamber length in the barrel determines if it will be safe to fire. For 12 gauge 870s, the maximum shell length is 2 + 3 ⁄ 4  in (70 mm) for non-magnums, 3 in (76 mm) for magnums, and 3 + 1 ⁄ 2  in (89 mm) for super magnums. Since barrels can be changed, it

897-454: The basic "Express" models, which were added as a lower-cost alternative to the original Wingmaster line, sales topped seven million guns. On April 13, 2009, the ten millionth Model 870 was produced. The 870 features a bottom-loading, side ejecting receiver and a tubular magazine under the barrel. The gun comes with a plug for migratory bird hunting which reduces the magazine's capacity to two rounds. It has dual action bars, internal hammer, and

936-399: The bolt moves rearwards, a single shell is released from the magazine, and is pushed backwards to come to rest on the elevator. As the forend reaches the rear and begins to move forward, the elevator lifts up the shell, lining it up with the barrel. As the bolt moves forward, the round slides into the chamber, and the final portion of the forend's travel locks the bolt into position. A pull of

975-486: The carrier, visible from below the gun. The cut-out, combined with modified machining on the underside of the slide assembly, allows the action to be opened with a shell on the carrier. There are hundreds of variations of the Remington 870 in 12, 16, 20, 28 gauges and .410 bore. All Remington 870 versions are built on the same platform and receiver, but there are small differences that can be more than just cosmetic. In 1969, Remington introduced 28 gauge and .410 bore models on

1014-400: The chamber, or cycled from the magazine, which is then topped off with another round. Pump shotguns with detachable box magazines or even drums exist, and may or may not allow the magazine to be inserted without stripping the top round. Nearly all pump-actions use a back-and-forward motion of the forend to cycle the action. Only a few pump-actions use the "reverse" or forward-and-back motion of

1053-470: The forend to cycle the action, a few examples are the Russian RMB-93 and South African NeoStead 2000 . The forend is connected to the bolt by one or two bars; two bars are considered more reliable because it provides symmetric forces on the bolt and pump and reduces the chances of binding. The motion of the bolt back and forth in a tubular magazine model will also operate the elevator , which lifts

1092-561: The gun patented in America on the 22nd of May in 1866 by Josiah V. Meigs although the pump action was actuated via the trigger guard rather than a sliding handguard underneath the barrel. The first magazine-using pump-action firearm to operate using a sliding handguard underneath the barrel was the firearm patented by William Krutzsch of Britain on the 27th of August in 1866, a few months after Meigs. Many older pump-action shotguns can be fired faster than modern ones, as they often did not have

1131-571: The import of most Norinco firearms and ammunition into the United States was blocked under new trade rules when China's permanent normal trade relations status was renewed. The prohibition did not apply to sporting shotguns or shotgun ammunition , however. In 1994, U.S. Customs agents conducted a sting operation named Operation Dragon Fire against Atlanta -based importers of Norinco firearms as well as Poly Technologies . Seven officials were arrested after agreeing to smuggle 2,000 fully automatic Chinese-made variants of AK-47s to undercover agents

1170-459: The improved Remington Model 29). John Browning designed the Remington Model 17 (which was later adapted by Ithaca into the Ithaca 37 ), which served as the basis for the Remington 31 . The Model 31 was marketed as the “ball-bearing repeater” and was well-received, but its many machined and handfitted parts made the gun expensive to manufacture. Consequently, it struggled in sales compared to

1209-550: The majority of pump-action shotguns and rifles use a fixed tubular magazine . This makes for slow reloading, as the cartridges have to be inserted individually into the magazine of the firearm. However, some pump-action shotguns and rifles, including the Russian Zlatoust RB-12 , Italian Valtro PM5 , American Remington 7600 series, and the Mossberg 590M, use detachable box magazines . A pump-action firearm

1248-611: The officials believed may have been connected to the American Mafia . At least one official, Hammond Ku, attempted to sell Chinese-produced tanks and rocket launchers to the undercover agents. In August 2003, the Bush administration imposed sanctions on Norinco for allegedly selling missile-related goods to Iran . These sanctions led to a prohibition on imports into the US of the remaining types of firearms and ammunition not covered by

1287-466: The same time). Initially, the Rem Chokes were offered only in 12 gauge in barrel lengths of 21, 26 and 28 in (530, 660 and 710 mm). The following year the availability was expanded to the 20 gauge and included other barrel lengths. The 870's production for over 30 years had a design flaw whereby a user could fail to press a shell all the way into the magazine when loading – so that

1326-464: The shell latch did not engage the shell – which could result in tying up the gun. This was caused by the shell slipping out of the magazine under the bolt in the receiver to bind the action, requiring rough treatment of the action or even disassembly. The potential issue was resolved with the introduction of the "Flexi Tab" carrier. Guns with this modification can be identified by the U-shaped cut-out on

1365-407: The shells from the level of the magazine to the level of the barrel. After firing a round, the bolt is unlocked and the forend is free to move. The shooter pulls back on the forend to begin the operating cycle. The bolt unlocks and begins to move to the rear, which extracts and ejects the empty shell from the chamber, cocks the hammer, and begins to load the new shell. In a tubular magazine design, as

1404-635: The shooter to mix different types of loads and for using low-power or specialty loads. Semi-automatic shotguns must use some of the energy of each round fired to cycle their actions, meaning that they must be loaded with shells powerful enough to reliably cycle. The pump-action avoids this limitation. In addition, like all manual action guns, pump-action guns are inherently more reliable than semi-automatic guns under adverse conditions, such as exposure to dirt, sand, or climatic extremes. Thus, until recently, military combat shotguns were almost exclusively pump-action designs. Like most lever-action rifles and shotguns,

1443-431: The trigger will fire the next round, where the cycle begins again. Most pump-action firearms do not have any positive indication that they are out of ammunition, so it is possible to complete a cycle and have an empty chamber. The risk of running out of ammunition unexpectedly can be minimized in a tubular magazine firearm by topping off the magazine by loading new rounds to replace the rounds that have just been fired. This

In modern shotguns, the fore-end can be replaceable and often include picatinny rails or M-LOK for mounting accessories such as a tactical light , and the traditional straight grip might be replaced with a pistol grip for a more stable control. Modern pump shotgun designs, such as the Remington 870 and Mossberg 500 , have a safety feature called

Later pump-action rifles were also manufactured by Winchester, Marlin , Browning and Remington . A "reverse pump-action" design can sometimes be found, where the extraction is done by pushing the fore-end forwards, and re-chambered by pulling backwards. One such 21st-century variant
