FR8
The FR 7 and FR 8 are bolt-action rifles adopted by Spain in the 1950s. The "FR" stands for ''Fusil Reformado'' in Spanish ("Converted Rifle" in English). The FR 7 is a variant of the "Spanish M93 Mauser" bolt action while the FR 8 is based on the "Mauser System 98" bolt action. Due to their light weight, short barrel and the calibre used, their recoil and muzzle blast are relatively heavy. History The FR7 and FR8 were introduced in the 1950s when the Spanish military was already implementing the CETME automatic rifle, but did not yet have sufficient inventory to equip and train all troops. The rifles were made from existing stockpiles of Mauser bolt-action rifles. The FR-7 was a modification of the Model 1916 short rifle, which in turn was based on the Mauser Model 1893. These three rifles are often referred to as being "small ring" Mausers, as the receiver ring is smaller in diameter than the latter Model 1898 by .110-inch (1.410 inches vs. 1.300 inches). The FR-8 was develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt Action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, 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 the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. 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. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Karabiner 98k
The Karabiner 98 kurz (; "carbine 98 short"), often abbreviated Karabiner 98k, Kar98k or K98k and also sometimes incorrectly referred to as a K98 (a K98 is a Polish carbine and copy of the Kar98a), is a bolt-action rifle chambered for the 7.92×57mm Mauser cartridge. It was adopted on 21 June 1935 as the standard service rifle by the German ''Wehrmacht.''K98k Mauser Page Retrieved 28 March 2007. It was one of the final developments in the long line of Mauser military rifles. Although supplemented by semi-automatic and fully automatic rifles during World War II, the Karabiner 98k remained the primary German service rifle until the end of th ...

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms) , bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifling , rifled barrel, the distance is measured between opposing Rifling#C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gun is di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Blast
A muzzle blast is an explosive shockwave created at the muzzle of a firearm during shooting. Before a projectile leaves the gun barrel, it obturates the bore and "plugs up" the pressurized gaseous products of the propellant combustion behind it, essentially containing the gases within a closed system as a neutral element in the overall momentum of the system's physics. However, when the projectile exits the barrel, this functional seal is removed and the highly energetic bore gases are suddenly free to exit the muzzle and rapidly expand in the form of a supersonic shockwave (which can be often fast enough to momentarily overtake the projectile and affect its flight dynamics), thus creating the muzzle blast. The muzzle blast is often broken down into two components: an auditory component and a non-auditory component. The auditory component is the loud "Bang!" sound of the gunshot, and is important because it can cause significant hearing loss to surrounding personnel and al ...

CETME
CETME () is a Spanish government design and development establishment. While being involved in many projects CETME was mostly known for its small arms research and development. The CETME Model 58 and CETME Model L are its most notable projects. CETME also designed the CETME C2 9mm submachine gun, and the CETME Ameli light machine gun in 5.56×45mm NATO.

Guardia Civil
The Civil Guard ( es, Guardia Civil, link=no; ) is the oldest law enforcement agency in Spain and is one of two national police forces. As a national gendarmerie force, it is military in nature and is responsible for civil policing under the authority of both the Ministry of the Interior and the Ministry of Defence. The role of the Ministry of Defence is limited except in times of war when the Ministry has exclusive authority. The corps is colloquially known as the ' (reputable). In annual surveys, it generally ranks as the national institution most valued by Spaniards, closely followed by other law enforcement agencies and the armed forces. It has both a regular national role and undertakes specific foreign peacekeeping missions and is part of the European Gendarmerie Force. As a national gendarmerie force, the Civil Guard was modelled on the French National Gendarmerie and has many similarities. As part of its daily duties, the Civil Guard patrols and investigates crimes in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Nevada (Spain)
Sierra Nevada (; meaning "mountain range covered in snow") is a mountain range in the Andalusian province of Granada in Spain. It contains the highest point of continental Spain:The highest peak in Spanish territory is Teide on the island of Tenerife in the Canary Islands, which is politically Spanish but geographically part of Africa. Mulhacén, at above sea level. It is a popular tourist destination, as its high peaks make skiing possible in one of Europe's most southerly ski resorts, in an area along the Mediterranean Sea predominantly known for its warm temperatures and abundant sunshine. At its foothills is found the city of Granada, and a little further south, Almería and Málaga. Parts of the range have been included in the Sierra Nevada National Park. The range has also been declared a biosphere reserve. The Sierra Nevada Observatory and the IRAM radiotelescope are located on the northern slopes at an elevation of .

Gun Barrel
A gun barrel is a crucial part of gun-type weapons such as small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end ( muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, usually measured in inches or millimetres. The first firearms were made at a time when metallurgy was not advanced enough to cast tubes capable of withstanding the explosive forces of early cannons, so the pipe (often built from staves of metal) needed to be braced periodically along its length for structural reinforcement, producing an appearance somewhat reminiscent of storage barrels being stacked together, hence the English name.''A History of Warfare'' - Keegan, John, Vintage 1993. History Gun barrels are usually metal. However, the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle Grenade
A rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade were thrown by hand. The practice of projecting grenades with rifle-mounted launchers was first widely used during World War I and World War II and continues to the present, with the term "rifle grenade" now encompassing many different types of payloads including high explosive, fragmentation, anti-tank warheads, concussion, smoke, incendiary, and flare missiles. Rifle grenades have largely been supplanted in the infantry fire support role by a combination of grenade launchers (typically affixed to rifles) and disposable anti-armor rockets. History Early use Adaptation of grenades for use in rifles began around the 18th century, when cup-shaped dischargers were fitted to the barrels of flintlock muskets, with the grenades propelled by the force of a blank cartridge. During the early 20th century a Japanese Colonel Amazawa experimented ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
