Caracal
The Caracal pistol is a series of semi-automatic pistols manufactured by Caracal International L.L.C.[1] a subsidiary of Tawazun Holding from the United Arab Emirates. Newly arrived on a competitive market, the Caracal pistol series are the first pistols made in the United Arab Emirates.
In 2007, Tawazun Holding L.L.C. - the wholly owned subsidiary of the United Arab Emirates Offset Program Bureau (OPB) - has acquired the assets of Caracal International.[2]
As of 2011 Caracal pistols are also manufactured in Germany by Caracal GmbH operating from Suhl in Thuringia for the European market.[3] Caracal GmbH is a subsidiary of the German hunting rifle and shotgun manufacturer Merkel GmbH[4]which was acquired by Caracal International L.L.C. in 2007.
Beginning of 2012, Caracal has open a subsidiary in the United States, Caracal USA.
Scorpions are predatory arthropod animals of the order Scorpiones within the class Arachnida. They have eight legs and are easily recognized by the pair of grasping claws and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm (Typhlochactas mitchelli) to 20 cm (Hadogenes troglodytes).[1]
Scorpions are found widely distributed over all continents, except Antarctica, in a variety of terrestrial habitats except the high latitudetundra. Scorpions number about 1,752 described species,[2] with 13 extant families recognised to date. The taxonomy has undergone changes and is likely to change further, as a number of genetic studies are bringing forth new information.
Scorpion venom has a fearsome reputation, but only about 25 species are known to have venom capable of killing a human being.[3]At the Range with the CZ Scorpion Evo 3 A1 Submachine Gun

The M-10 was built predominantly from steel stampings. A notched cocking handle protrudes from the top of the receiver, and by turning the handle 90° would lock the bolt, and act as an indicator that the weapon is unable to fire. The M-10 has atelescoping bolt, which wraps around the barrel. This allows a more compact weapon, and balances the weight of the weapon over the pistol grip where the magazine is located. The M-10 fires from an open bolt, and in addition, the light weight of the bolt results in a rapid rate of fire. In addition, this design incorporates a built in feed ramp as part of the trigger guard (a new concept at the time) and to save on cost the magazine was recycled from the M3 Grease Gun, also originally designed by Gordon B. Ingram. The barrel is threaded to accept a suppressor, which worked by reducing the discharge's sound, without attempting to reduce the velocity of the bullet or rather stops air from rushing into the barrel, inhibiting the sonic signature. At the suggestion of the United States Army, it also acted as a foregrip to inhibit muzzle rise when fired. Ingram added a small bracket with a small strap beneath the muzzle to aid in controlling recoil during fully automatic fire.M134 Minigun
The M134 Minigun is a 7.62 mm, six-barreled machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). It features Gatling-style rotating barrels with an external power source, normally an electric motor. The "Mini" of the name is in comparison to designs that use a similar firing mechanism but larger shells, such as General Electric's earlier 20-millimeter M61 Vulcan, and "gun" for a caliber size smaller than that of a cannon, typically 20 mm and higher.
"Minigun" refers to a specific model of weapon, originally produced by General Electric. But the term "minigun" has popularly come to refer to any externally powered Gatling gun of rifle caliber. The term is also used to refer to guns of similar rates of fire and configuration sometimes, regardless of power source and caliber.
GLOCK 9x19
The Glock pistol, sometimes referred to by the manufacturer as Glock "Safe Action" Pistol, is a series of semi-automatic pistols designed and produced by Glock Ges.m.b.H., located in Deutsch-Wagram, Austria. The company's founder,engineer Gaston Glock, had no experience with firearm design or manufacture at the time their first pistol, the Glock 17, was being prototyped. Glock did, however, have extensive experience in advanced synthetic polymers, knowledge of which was instrumental in the company's design of the first successful line of pistols with a polymer frame. Glock introducedferritic nitrocarburizing into the firearms industry as an anti-corrosion surface treatment for metal gun parts.[5]
Despite initial resistance from the market to accept a "plastic gun" due to durability and reliability concerns, Glock pistols have become the company's most profitable line of products, commanding 65% of the market share of handguns for United States law enforcement agencies[6] as well as supplying numerous national armed forces and security agencies worldwide. Glocks are also popular weapons amongst civilians for home/self defense and concealed/open carry
A shotgun (also known as a scattergun and peppergun,[1] or historically as a fowling piece) is a firearm that is usually designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot, or a solid projectile called a slug. Shotguns come in a wide variety of sizes, ranging from 5.5 mm (.22 inch) bore up to 5 cm (2 inch) bore, and in a range of firearm operating mechanisms, including breech loading, single-barreled, double or combination gun, pump-action, bolt-, and lever-action, semi-automatic, and even fully automatic variants.
A shotgun is generally a smoothbore firearm, which means that the inside of the barrel is not rifled. Preceding smoothbore firearms, such as the musket, were widely used by armies in the 18th century. The direct ancestor to the shotgun, the blunderbuss, was also used in a similar variety of roles from self defence to riot control. It was often used by cavalry troops due to its generally shorter length and ease of use, as well as by coachmen for its substantial power. However, in the 19th century, these weapons were largely replaced on the battlefield withbreechloading rifled firearms, which were more accurate over longer ranges. The military value of shotguns was rediscovered in the First World War, when American forces used 12-gauge pump action shotguns in close-quarters trench fighting to great effect. Since then, it has been used in a variety of roles in civilian, law enforcement, and military applications.
The shot pellets from a shotgun spread upon leaving the barrel, and the power of the burning charge is divided among the pellets, which means that the energy of any one ball of shot is fairly low. In a hunting context, this makes shotguns useful primarily for hunting birds and other smallgame. However, in a military or law enforcement context, the large number of projectiles makes the shotgun useful as a close quarters combat weapon or a defensive weapon. Shotguns are also used for target shooting sports such as skeet, trap, and sporting clays. These involve shooting clay disks, known as clay pigeons, thrown in various ways
The AK-47 is a selective-fire, gas-operated 7.62×39mm assault rifle, first developed in the USSR by Mikhail Kalashnikov. It is officially known as Avtomat Kalashnikova (Russian: Автомат Калашникова). It is also known as a Kalashnikov, an AKor in Russian slang, Kalash.
Design work on the AK-47 began in the last year of World War II (1945). After the war in 1946, the AK-46 was presented for official military trials. In 1948 the fixed-stock version was introduced into active service with selected units of the Soviet Army. An early development of the design was the AKS (S—Skladnoy or "folding"), which was equipped with an underfolding metal shoulder stock. In 1949, the AK-47 was officially accepted by the Soviet Armed Forces[10] and used by the majority of the member states of the Warsaw Pact.
The original AK-47 was one of the first assault rifles of 2nd generation, after the German StG 44.[11] Even after six decades the model and its variants remain the most widely used and popular assault rifles in the world because of their durability, low production cost, and ease of use. It has been manufactured in many countries and has seen service with armed forces as well as irregular forces worldwide. The AK-47 was the basis for developing many other types of individual and crew-served firearms. More AK-type rifles have been produced than all other assault rifles combined.[3]
The Heckler & Koch MP5 (from German: Maschinenpistole 5, "machine pistol model 5") is a 9mm submachine gun of German design, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar. There are over 100 variants,[4] including a semi-automatic version.
The MP5 is one of the most widely used submachine guns in the world,[5] having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations.[3] In the 1990s, Heckler & Koch developed theHeckler & Koch UMP, the MP5's successor; both are available as of 2012.[6
Operating mechanism
The bolt rigidly engages the barrel extension—a cylindrical component welded to the receiver into which the barrel is pinned. The delay mechanism is of the same design as that used in the G3 rifle. The two-part bolt consists of a bolt head with rollers and a bolt carrier. The heavier bolt carrier lies up against the bolt head when the weapon is ready to fire and inclined planes on the front locking piece lie between the rollers and force them out into recesses in the barrel extension.[8]
When fired, expanding propellant gases produced from the burning powder in the cartridge exert rearward pressure on the bolt head transferred through the base of the cartridge case as it is propelled out of the chamber. A portion of this force is transmitted through the rollers projecting from the bolt head, which are cammed inward against the inclined flanks of the locking recesses in the barrel extension and to the angled shoulders of the locking piece. The selected angles of the recesses and the incline on the locking piece produce a velocity ratio of about 4:1 between the bolt carrier and the bolt head. This results in a calculated delay, allowing the projectile to exit the barrel and gas pressure to drop to a safe level before the case is extracted from the chamber.The delay results from the amount of time it takes for enough recoil energy to be transferred through to the bolt carrier in a sufficient quantity for it to be driven to the rear against the force of inertia of the bolt carrier and the forward pressure exerted against the bolt by the recoil spring. As the rollers are forced inward they displace the locking piece and propel the bolt carrier to the rear. The bolt carrier's rearward velocity is four times that of the bolt head since the cartridge remains in the chamber for a short period of time during the initial recoil impulse. After the bolt carrier has traveled rearward 4 mm, the locking piece is withdrawn fully from the bolt head and the rollers are compressed into the bolt head. Only once the locking rollers are fully cammed into the bolt head can the entire bolt group continue its rearward movement in the receiver, breaking the seal in the chamber and continuing the feeding cycle.
Since the 9×19mm Parabellum cartridge is relatively low powered, the bolt does not have an anti-bounce device like the G3, but instead the bolt carrier contains tungsten granules that prevent the bolt group from bouncing back after impacting the barrel extension. The weapon has a fluted chamber that enhances extraction reliability by bleeding gases backwards into the shallow flutes running along the length of the chamber to prevent the cartridge case from expanding and sticking to the chamber walls (since the bolt is opened under relatively high barrel pressure). A spring extractor is installed inside the bolt head and holds the case securely until it strikes the ejector arm and is thrown out of the ejection port to the right of the receiver. The lever-type ejector is located inside the trigger housing (activated by the movement of the recoiling bolt).
The Uzi (Hebrew: עוזי, officially cased as UZI) is a family of Israeli open-bolt, blowback-operated submachine guns. Smaller variants are considered to be machine pistols. The Uzi was one of the first weapons to use a telescoping bolt design which allows the magazine to be housed in the pistol grip for a shorter weapon.
The first Uzi submachine gun was designed by Major Uziel Gal in the late 1940s. The prototype was finished in 1950. First introduced to IDF special forces in 1954, the weapon was placed into general issue two years later. The Uzi has found use as a personal defense weapon by rear-echelon troops, officers, artillery troops and tankers, as well as a frontline weapon by elite light infantry assault forces.
The Uzi has been exported to over 90 countries.[2] Over its service lifetime, it has been manufactured by Israel Military Industries, FN Herstal, and other manufacturers. From the 1960s through the 1980s, more Uzi submachine guns were sold to more military and police markets than any other submachine gun ever made.[5]
Design
The Uzi uses an open-bolt, blowback-operated design quite similar to the Jaroslav Holeček-designed Czech ZK 476 (prototype only)[6] and the production Sa 23, Sa 24, Sa 25, and Sa 26 series of submachineguns, from which it was inspired. The open bolt design exposes the breech end of the barrel, and improves cooling during periods of continuous fire. However, it means that since the bolt is held to the rear when cocked, the receiver is more susceptible to contamination from sand and dirt. It uses a telescoping bolt design, in which the bolt wraps around the breech end of the barrel.[7] This allows the barrel to be moved far back into the receiver and the magazine to be housed in the pistol grip, allowing for a heavier, slower-firing bolt in a shorter, better-balanced weapon.[5]
The weapon is constructed primarily from stamped sheet metal, making it less expensive per unit to manufacture than an equivalent design machined from forgings. With relatively few moving parts, the Uzi is easy to strip for maintenance or repair. The magazine is housed within the pistol grip, allowing for intuitive and easy reloading in dark or difficult conditions, under the principle of "hand finds hand". The pistol grip is fitted with a grip safety, making it difficult to fire accidentally. However, the protruding vertical magazine makes the gun awkward to fire when prone.[7] The Uzi features a bayonet lug.[8]
Controls are relatively simple.[citation needed] The non reciprocating charging handle on the top of the receiver cover is used to retract the bolt. Submachine gun variants have a ratchet safety mechanism which will catch the bolt and lock its movement if it is retracted past the magazine, but not far enough to engage the sear. Semiauto civilian market versions of the Uzi usually do not have or need this feature. When the handle is fully retracted to the rear, the bolt will cock/catch on the sear mechanism and the handle can then be released to spring fully forward under power of a small spring attaching it to the topcover. It will remain forward during firing of the weapon since it does not reciprocate when the bolt is thrust backward by the force of a cartridge firing, or forward by the main action spring. The military/police versions of the Uzi will fire immediately upon chambering a cartridge as the Uzi is an open bolt weapon. This feature is extensively modified on commercial market semiauto Uzis in order to prevent fully automatic fire. The semiauto variants (whether rifle or pistol) fire from the closed bolt, with the entire bolt mechanism designed as a two-piece mechanism. The main bolt functions much like the original, but will close upon release of the charging handle. A mechanism containing part of the shape of the bolt and firing pin remains cocked to the rear. That striker like mechanism is only released forward when the trigger is pulled.
There are two external safety mechanisms on the Uzi, one being a selector lever which includes positions for "safe" which locks the sear and prevents movement of the bolt, "semi", which is one notch forward, which will allow the weapon to function in semiautomatic single shot mode, requiring the trigger to be pulled for each shot, and then "automatic" with the selector all the way forward, which will disengage part of the sear mechanism, allowing use of the trigger to control the firing mechanism. Once on automatic, the user may hold the trigger back and the weapon will fire until the magazine is empty. The bolt will then most likely come to rest on an empty chamber once the magazines is empty since the Uzi does not employ a bolt hold open on empty magazine mechanism like those found on military weapons that fire from the closed bolt. A very rare semiautomatic version made by FN Herstal and sold in Europe for a short time during the 1970s functioned exactly the same way, but the most forward setting on the selector lever was eliminated and blocked off. That variant was not approved for commercial import into the USA and was eventually withdrawn from production after having a relatively short commercial life in Western Europe and Canada.
The second external safety mechanism is a grip safety, located at the rear of the grip and meant to help prevent accidental discharge if the weapon is dropped, or the user loses a firm grip on the weapon during firing. The grip safety on the Uzi uses a stronger spring than that found on most handguns with a somewhat similar mechanism (US M1911, German Luger). The pistol grip must be firmly held by the user in order to allow the weapon to function, regardless of any manipulation of other controls.
The trigger mechanism is a conventional firearm trigger, but functions only to control the release mechanism for either the bolt (submachine gun) or firing pin holding mechanism (semiauto) since the UZI does not incorporate any internal cocking or hammer mechanism. While the system is much more mechanically simple than say, the Heckler & Koch MP5, it creates a noticeable delay from the point the user pulls the trigger and the point that the weapon actually fires. This delay is common with weapons that fire from the "open bolt".
The magazine release button/lever is located on the lower portion of the pistol grip and is intended to be manipulated by the non-firing hand. The paddle-like button lays flush with the pistol grip in order to help prevent accidental release of the magazine during soldier maneuvers and day to day activity.
Of the two stocks employed by the IDF, the wooden stock was the simpler and more robust of the two. The wooden stock is quick-detachable through the use of a release mechanism on the bottom side. Some commercial variants of the Uzi lacked the quick release mechanism and have the stock bolted in place. The second, and by far most popular stock on the Uzi was a unique folding stock which folds under the gun. It is robust but complex and was replaced by a side folding stock on the more compact models. Neither of the folding stocks can be quickly or easily removed from the weapon.
When the gun is de-cocked (the magazine must be removed or at least lowered enough to prevent feeding a round in the chamber in order to prevent the weapon from firing when it is being de-cocked), the ejector port closes, preventing entry of dust and dirt. Though the Uzi's stamped-metal receiver is equipped with pressed reinforcement slots to accept accumulated dirt and sand, the weapon can still jam with heavy accumulations of sand in desert combat conditions when not cleaned regularly.[9] The magazine must be removed prior to "decocking" the weapon or else the bolt will feed a round when being let forward and then leave the firing pin resting on an unfired primer, which can then fire if the weapon is knocked or dropped. The decocking procedure is to remove the magazine, check the chamber (which should be empty) and then pull the trigger which will release the bolt to fall on the empty chamber. The magazine may then be re-inserted. To ready the weapon for firing again, the bolt handle must be retracted to the rear. Use of the selector switch is irrelevant to this process, except that it will prevent the bolt from moving when it is in the "safe" position.

The Israel Military Industries Desert Eagle is a large-framed gas-operated semi-automatic pistol designed by Magnum Research in the US. Over the past 25 years, MRI has been responsible for the design and development of the Desert Eagle pistol. The design was refined and the actual pistols were manufactured by Israel Military Industries until 1995, when MRI shifted the manufacturing contract to Saco Defense in Saco, Maine. In 1998, MRI moved manufacturing back to IMI, which later reorganized under the name Israel Weapon Industries. Both Saco and IMI/IWI were strictly contractors: all of the intellectual property, including patents, copyrights and trademarks, are the property of Magnum Research. Since 2009, the Desert Eagle Pistol has been produced in the USA at MRI’s Pillager, MN facility.[2] Kahr Arms acquired Magnum Research in the middle of 2010.[3] The Desert Eagle has been featured in roughly 500 motion pictures and TV films, considerably increasing its popularity and boosting sales.[4]
Magnum Research has marketed various versions of the short recoil Jericho 941 pistol under the Baby Eagle and Desert Eagle Pistol names; these have no functional relationship to the Desert Eagle and bear only a moderate cosmetic resemblance.[5]
Design work on a new family of pistols commenced in September 1989 focused primarily on the U.S. commercial and law enforcement markets. In 1991, USP prototypes participated in rigorous testing alongside H&K's entry in the Offensive Handgun Weapon System (OHWS) program requested by the U.S. Special Operations Command (USSOCOM) and which would later result in the Mk 23 Mod 0. The USP prototypes were then refined in 1992, based on input from the OHWS trials, and the design was finalized in December of the same year. The USP was formally introduced in January 1993[2] with the USP40 model (the base version) chambered for the increasingly popular .40 S&W cartridge, followed soon by the USP9(using the 9x19mm Parabellum cartridge), and in May 1995—the USP45 (caliber .45 ACP).
The USP marked the first time Heckler & Koch chose to incorporate many traditional handgun design elements, such as those of John Browning's M1911, in one pistol.[3] Two principles guided its development—the first being the use of a moldedpolymer frame, and the second being the creation of a "pistol paradigm". Heckler & Koch observed the strong points of its previous successful pistols for insight in developing the USP. Previous H&K pistol innovations include the unique squeeze-cocking mechanism of the P7, the precise roller-delayed blowback operation of the P9S, and the plastic frame and double action only trigger system used in the VP70Z. In contrast to these ambitious designs, the USP uses a Browning-style cam-locked action, similar to that developed by John Browning for use in the Hi-Power and M1911 pistols.[4][5]
The AWP is a powerful bolt-action sniper rifle available to both teams. It is renowned for being able to instantly kill a player with one hit on any part of the body except the legs. For this reason, the AWP is one of the most popular and widely used weapons in Counter-Strike. It is also the most powerful weapon in the Counter-Strike series.The Accuracy International Arctic Warfare rifle is a family of bolt-action sniper rifles 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.
Arctic Warfare rifles are generally fitted with a Schmidt & Bender PM II telescopic sight with fixed or variable magnification. Variable telescopic sights can be used if the operator wants more flexibility to shoot at varying ranges, or when a wide field of view is required. Accuracy International actively promotes fitting the German-made Schmidt & Bender PM II/MILITARY MK II product line as sighting components on their rifles, which is rare for a rifle manufacturer. The German and Russian Armies preferred a telescopic sight made by Zeiss over Accuracy International's preference.
M4A1
The Colt M4A1 carbine is the primary weapon used by SEAL operators. A shorter, more compact version of the M16A2 rifle, it was specially designed for U.S. Special Operations Forces. In 1994, U.S. Special Operations Command (USSOCOM) and the Navy developed the Special Operations Peculiar (SOPMOD) M4A1 Accessory Kit to make this weapon exceptional in versatility, lethality, and effectiveness. The M4A1 is a high-tech, multiple-use assault rifle that can be configured by the operator with multiple combinations of advanced optics, lasers and lighting systems for rapid and accurate target acquisition in daylight or at night. It fires in both semi- and automatic modes, and is effective for both close-in engagements and long-range targets. The M4A1 excels in Close Quarters Battle and Counterterrorist operations. It fires a high-velocity 5.56mm round, essential when taking on terrorists wearing body armor or bullet-proof vests. This rifle can also be quickly and easily converted to a grenade launcher or shotgun.
Future Version
2005-2010 Integrated Carbine – The SOPMOD Block 3 upgrade will result in a more streamlined version of the M4A1 Carbine, designated the Integrated Carbine. It will incorporate all of the refinements for the M4A1 carbine by getting the optics and lasers off the weapon and into the weapon itself, and it will provide a thermal sighting device. Mode switches and buttons will be integrated into the vertical grip to activate lasers, thermal and other sights, and visible light. The thermal sighting component might very well have the ability to be linked to Joint Surveillance and Target Attack Radar System (JSTARS).
