.950 JDJ
The .950 JDJ (24.1×70mm) is a powerful large caliber rifle cartridge developed by American gunsmith and weapon designer J. D. Jones of SSK Industries. Cartridge .950 JDJ cases are approximately 70 mm in length, and are based on a 20×110mm case shortened and necked up to accept the bullet. Projectiles are custom-made and most commonly weigh which is 8.2 ounces or over half a pound. Rifles As its name implies, rifles chambered for the cartridge have a groove diameter of . SSK received a "Sporting Use Exception" to de-regulate the rifles. Thus, in the United States, they can be owned like any other Title I rifle by an American citizen at age 18. The rifles use McMillan Firearms stocks and extraordinarily thick Krieger barrels bearing an muzzle brake. Overall, depending on options, the rifles weigh from and are therefore only useful for shooting from a bench rest or heavy bipod. Despite the weight, recoil is significant and shooters must be sure to choose compone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle
A rifle is a long-barreled firearm designed for accurate shooting, with a barrel that has a helical pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used extensively in warfare, law enforcement, hunting, shooting sports, and crime. The term was originally ''rifled gun'', with the verb ''rifle'' referring to the early modern machining process of creating groovings with cutting tools. By the 20th century, the weapon had become so common that the modern noun ''rifle'' is now often used for any long-shaped handheld ranged weapon designed for well-aimed discharge activated by a trigger (e.g., personnel halting and stimulation response rifle, which is actually a laser dazzler). Like all typical firearms, a rifle's projectile (bullet) is propelled by the contained defl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispano-Suiza HS
Hispano-Suiza () is a Spanish automotive–engineering company. It was founded in 1904 by Marc Birkigt and Damian Mateu as an automobile manufacturer and eventually had several factories in Spain and France that produced luxury cars, aircraft engines, trucks and weapons. In 1923, its French luxury car arm became a semi-autonomous partnership with the Spanish parent company. In 1946, the Spanish parent company sold all of its Spanish automotive assets to Enasa, a Spanish state-owned vehicle manufacturer, and the French arm continued as an independent aviation engine and components manufacturer under the Hispano-Suiza name. In 1968, Hispano-Suiza was taken over by the aerospace company Snecma, which is now part of the French Safran Group. An attempt to relaunch the marque was made by the company Hispano Suiza Cars associated with the Peralada Group (owned by the Suqué Mateu family) in 2019 with a fully-electric car. History Early years In 1898, a Spanish artillery captain, Emilio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

20×110mm
20 mm caliber is a specific size of popular autocannon ammunition. It is typically used to distinguish smaller-caliber weapons, commonly called "guns", from larger-caliber "cannons" (e.g. machine gun vs. autocannon). All 20 mm cartridges have an outside projectile (bullet) diameter and barrel bore diameter of . These projectiles are typically long, cartridge cases are typically long, and most are shells, with an explosive payload and detonating fuze. Weapons using this caliber range from anti-materiel rifles and anti-tank rifles to aircraft autocannons and anti-aircraft guns. Usage Twenty-millimeter-caliber weapons are generally not used to target individual soldiers, but have targets such as vehicles, buildings, or aircraft. Types of ammunition *High explosive (HE) *High explosive incendiary (HEI) *Armor-piercing (AP) * Semi-armor-piercing high explosive incendiary (SAPHEI) * Armor-piercing discarding sabot (APDS) *High explosive fragmentation tracer (HEF-T) * High ...

Ounce
The ounce () is any of several different units of mass, weight or volume and is derived almost unchanged from the , an Ancient Roman unit of measurement. The avoirdupois ounce (exactly ) is avoirdupois pound; this is the United States customary and British imperial ounce. It is primarily used in the United States to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere. Although the avoirdupois ounce is the mass measure used for most purposes, the 'troy ounce' of exactly is used instead for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc. The term 'ounce' is also used in other contexts: * The ounce-force is a measure of force (see below). * The fluid ounce is a measure of volume. Historically, a variety of different ounces measuring mass or volume were used in different jurisdictions by different trades and at diff ...

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article on Limcat Und ...

Telescopic Sight
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a ''reticle'' – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical aiming aids and primitive predecessors of telescopic sights were created that had practical or pe ...

Bipod
A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix ''bi-'' and Greek root ''pod'', meaning "two" and "foot" respectively. Bipods are designed to support the weight of the weapon's front portion and barrel, and provide significant stability against unwanted side-to-side movements (i.e. canting) while allowing free movements pivoting around the transverse axis ( pitching). Most modern bipods have foldable and/or telescoping legs, and allow some limited movements around the vertical axis ( panning) and even the longitudinal axis ( tilting). A bipod by itself, with only two supporting legs, is not completely stable and needs to be reinforced by at least one more point of support to be steady, especially against the horizontal shearing force from recoils. This third point of support is typically the buttstock that is firmly pushed/braced against the shooter's body ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M16 Rifle
The M16 rifle (officially designated Rifle, Caliber 5.56 mm, M16) is a family of military rifles adapted from the ArmaLite AR-15 rifle for the United States military. The original M16 rifle was a 5.56×45mm automatic rifle with a 20-round magazine. In 1964, the M16 entered US military service and the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the US military's standard service rifle.Urdang, p. 801. The M16A1 incorporated numerous modifications including a bolt-assist, chrome-plated bore, protective reinforcement around the magazine release, and revised flash hider. In 1983, the US Marine Corps adopted the M16A2 rifle and the US Army adopted it in 1986. The M16A2 fires the improved 5.56×45mm (M855/SS109) cartridge and has a newer adjustable rear sight, case deflector, heavy barrel, improved handguard, pistol grip and buttstock, as well as a semi-auto and three-round burst fire se ...

M4 Rifle
The M4 carbine (officially Carbine, Caliber 5.56 mm, M4) is a 5.56×45mm NATO, gas-operated, magazine-fed carbine developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle. The M4 is extensively used by the United States Armed Forces, with decisions to largely replace the M16 rifle in United States Army (starting 2010) and United States Marine Corps (USMC) (starting 2016) combat units as the primary infantry weapon and service rifle. The M4 has been adopted by over 60 countries worldwide, and has been described as "one of the defining firearms of the 21st century". Since its adoption in 1994, the M4 has undergone over 90 modifications to improve the weapon's ergonomics and modularity, including: the M4A1, which strengthened the barrel and removed the burst-fire option; the SOPMOD, an accessory kit containing optical attachments; and the underbarrel M203 grenade launcher. In April 2022, the U.S. Army selected the SIG MCX SPEAR as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
308 Winchester
The .308 Winchester is a smokeless powder rimless bottlenecked rifle cartridge widely used for hunting, target shooting, police, military, and personal protection applications globally. It is similar but not identical to the 7.62×51mm NATO cartridge. History During the 1940s, the .300 Savage became the basis for experiments on behalf of the U.S. military that resulted in the development of the T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated the T65 and was similar to the .300 Savage case, but with less taper. The experimental cases were made from standard .30-06 Springfield cases which gave a little less capacity than standard .300 Savage cases because the Frankford Arsenal cases had slightly thicker case walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. military .30-06 Springfield service cartridge.
