Flash memory is an electronic (solid-state) non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory are named after the NAND and NOR logic gates. The individual flash memory cells, consisting of floating-gate MOSFETs, exhibit internal characteristics similar to those of the corresponding gates.
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 and 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.
A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a muzzle device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances that the shooter will be blinded in low-light shooting conditions. Contrary to popular belief, it is only a minor secondary benefit if a flash suppressor reduces the intensity of the flash visible to the enemy.
A USB flash drive is a data storage device that includes flash memory with an integrated USB interface. It is typically removable, rewritable and much smaller than an optical disc. Most weigh less than 30 g (1 oz). Since first appearing on the market in late 2000, as with virtually all other computer memory devices, storage capacities have risen while prices have dropped. As of March 2016, flash drives with anywhere from 8 to 256 gigabytes (GB) were frequently sold, while 512 GB and 1 terabyte (TB) units were less frequent. As of 2018, 2 TB flash drives were the largest available in terms of storage capacity. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to last between 10 and 100 years under normal circumstances.
A gunshot is a single discharge of a gun, typically a man-portable firearm, producing a visible flash, a powerful and loud shockwave and often chemical gunshot residue. The term can also refer to a ballistic wound caused by such a discharge.
The Bizon is a 9mm submachine gun developed in 1993 at Izhmash by a team of engineers headed by Victor Kalashnikov. Alexei Dragunov, youngest son of Yevgeny Dragunov, was also a member of the design team.
The Colt Automatic Rifle-15 or CAR-15 was a family of M16 rifle based firearms marketed by Colt in the 1960s and early 1970s. However, the term "CAR-15" is most commonly associated with the Colt Commando(AKA: XM177); these select-fire carbines have ultrashort 10.5-inch (270 mm) and 11.5-inch (290 mm) barrels with over-sized flash suppressors.
Transitional ballistics, also known as intermediate ballistics, is the study of a projectile's behavior from the time it leaves the muzzle until the pressure behind the projectile is equalized, so it lies between internal ballistics and external ballistics.
Suppression may refer to:
The OTs-14 Groza is a Russian selective fire bullpup assault rifle chambered for the 7.62×39 round and the 9×39mm subsonic round. It was developed in the 1990s at the TsKIB SOO in Tula, Russia.
The Barrett REC7 is an American firearm manufactured as a selective-fire fully-automatic and semi-automatic rifle by Barrett Firearms. It is an M4 carbine utilizing a short-stroke gas piston system. REC7 is available in either 5.56×45mm NATO or 6.8mm Remington SPC. The REC7 is Barrett’s second AR-pattern rifle chambered for the 6.8mm Remington SPC cartridge, the first being the Barrett M468 rifle. The 6.8 SPC-chambered M468 rifle employed the same direct gas-impingement system as the M4.
A contact shot is defined as a gunshot wound incurred while the muzzle of the firearm is in direct contact with the body at the moment of discharge. Contact shots are often the result of close range gunfights, suicide, or execution.
A muzzle booster or recoil booster is a device fixed to the muzzle of a firearm, intended to harness the energy of the escaping propellant to augment the force of recoil on portions of the firearm. Muzzle boosters are usually used to improve the reliability and/or rate of fire of a recoil operated firearm. The muzzle booster is distinct from the muzzle brake, which is designed to use the propellant gases to reduce the recoil of the firearm. However, unlike a muzzle brake, a muzzle booster uses the pressure of the expanding gases, rather than the reaction force, and it does not alter the felt recoil of the weapon, it merely adds more energy to the operating components.
Muzzle flash is the visible light of a muzzle blast, which is caused by the sudden release and expansion of high-temperature, high-pressure gases from the muzzle of a firearm. The blast and flash are caused by the combustion products of the gunpowder, and any remaining unburned powder, mixing with the ambient air. The size and shape of the muzzle flash is dependent on the combustion energy of propellant being used, the amount of combustible ejecta remaining, and any devices attached to the muzzle.
A muzzle shroud, linear compensator or concussion reduction device is a sleeve that attaches to and extends beyond the muzzle of a firearm to redirect some of the noise and concussion from the muzzle blast forward and away from the shooter and others standing behind and to the sides.
Advanced Armament Corporation or AAC is an American company that develops and manufactures firearms, firearm suppressors, muzzle devices and related accessories.
A silencer, also known as a sound suppressor, suppressor or sound moderator, is a muzzle device that reduces the acoustic intensity of the muzzle report and eliminates muzzle flash when a gun is discharged, by modulating the speed and pressure of the gas ejection from the muzzle and hence suppressing the muzzle blast. Like a muzzle brake, a silencer can be a detachable accessory mounted separately onto the muzzle, or an integral part of the barrel.
The Crazy Horse rifle or M14SE is a semi-automatic designated marksman rifle based on the M14 rifle. It is chambered for the 7.62×51mm NATO cartridge and is built by Smith Enterprise Inc.
The Wind Talker sound suppressor is a direct-connect sound suppressor made by Smith Enterprise Inc. for use by the US military on M14 rifles and M4 carbines that utilize a Vortex Flash Hider. It is an improvement over the older M14 Direct Connect sound suppressor.
