SAC-46 (handgun)
The SAC-46 (aka: Flying Dragon and "Gun, Dart, Carbon Dioxide Propelled") is an American clandestine handgun from 1945 which was developed for the Office of Strategic Services (OSS), a predecessor to the Central Intelligence Agency (CIA). Design For their clandestine overseas activities during World War II the OSS was interested in weapons that could neutralize opponents securely at a distance without being aural or visual detectable at a distance, e.g. sound suppressed and flash suppressed firearms or crossbows. One of their ideas in 1943 was the SAC-46 pistol, which was intended to fire a special designed poisoned dart propelled by a commercial type CO2-cartridge like an air gun. The ammunition for the gun is a dart made of transparent red plastic with a metal tip and a rubber gasket at the base of the tip. The dart has four fins at the tail, is about 5.75 in long with a diameter of ca. 0.5 in. The gun can be broken down into three pieces: the main body and two 16 inch bar ...

Pistol
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict laws and regulations governing their manufa ...

Takedown Gun
A takedown gun (typically a takedown rifle or takedown shotgun) is a long gun designed to be taken apart significantly reducing its length, making it easier to store, pack, transport and conceal. A variety of barrel, stock, and receiver designs have been invented to facilitate takedown. For example, the hinged design of many break-action firearms allows takedown. Some regular firearms can be modified to allow takedown after custom gunsmithing. Rifles American gun manufacturers including Marlin, Ruger, Savage, and Winchester have made takedown rifles since the late 1800s. Some early examples include the Browning 22 Semi-Auto rifle, Remington Model 24 and Remington Model 8 made by Fabrique Nationale and Remington Arms. Many militaries in the early 20th century also experimented with takedown systems, particularly for the use by paratroopers. An example of this being the Japanese experimental TERA Rifles. Shotguns Most single barrel and double barrel shotguns readily ...

Air Guns Of The United States
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in E ...

Trial And Research Firearms Of The United States
In law, a trial is a coming together of parties to a dispute, to present information (in the form of evidence) in a tribunal, a formal setting with the authority to adjudicate claims or disputes. One form of tribunal is a court. The tribunal, which may occur before a judge, jury, or other designated trier of fact, aims to achieve a resolution to their dispute. Types by finder of fact Where the trial is held before a group of members of the community, it is called a jury trial. Where the trial is held solely before a judge, it is called a bench trial. Hearings before administrative bodies may have many of the features of a trial before a court, but are typically not referred to as trials. An appeal (appellate proceeding) is also generally not deemed a trial, because such proceedings are usually restricted to a review of the evidence presented before the trial court, and do not permit the introduction of new evidence. Types by dispute Trials can also be divided by the type ...

Iron Sights
Iron sights are a system of physical alignment markers (usually made of metallic material) used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearm, airgun, crossbow or even compound bow), or less commonly as a primitive finder sight for optical telescopes. The earliest sighting device, it relies completely on the viewer's naked eye (mostly under ambient lighting), and is distinctly different to optical sights such as telescopic sights, reflector (reflex) sights, holographic sights and laser sights, which make use of optical manipulation and/or active illumination, as well as the newer optoelectronics, which use digital imaging and even incorporate augmented reality. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a rear sight nearer (or ''proximally'') to the shooter's eye, and a front sight farther forward (or ''distally'') near the muzzle. During aiming, the shooter aligns h ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is " V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in ''ampl ...

Safety (firearms)
Close-up shot of a safety of an M16A2 rifle In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties can generally be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for example, toggling a lever from "on" to "off" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively. Firearms with the ability to allow the user to select various fire modes may have separate switches for safety and for mode selection (e.g. Thompson submachine gun) or may have the safety integrated with the mode selector as a fire selector with positions from safe to semi-automatic to full-automatic fire (e.g. M16). Some firearms manufactured after the late 1990s and early 2000s include a mandatory integral locking mecha ...

Bayonet Mount
A bayonet mount (mainly as a method of mechanical attachment, such as fitting a lens to a camera using a matching lens mount) or bayonet connector (for electrical use) is a fastening mechanism consisting of a cylindrical male side with one or more radial pins, and a female receptor with matching L-shaped slot(s) and with spring(s) to keep the two parts locked together. The slots are shaped like a capital letter L with serif (a short upward segment at the end of the horizontal arm); the pin slides into the vertical arm of the L, rotates across the horizontal arm, then is pushed slightly upwards into the short vertical "serif" by the spring; the connector is no longer free to rotate unless pushed down against the spring until the pin is out of the "serif". The bayonet mount is the standard light bulb fitting in the United Kingdom and in many countries that were members of the British Empire including Pakistan, Australia, Hong Kong, Fiji India, Sri Lanka, Ireland, and New ...

Air Gun
An air gun or airgun is a gun that fires projectiles pneumatically with compressed air or other gases that are mechanically pressurized ''without'' involving any chemical reactions, in contrast to a firearm, which pressurizes gases ''chemically'' via oxidation of combustible propellants that generates propulsive energy by breaking molecular bonds. Air guns come in both long gun (air rifle) and handgun (air pistol) forms. Both types typically propel metallic projectiles that are either diabolo-shaped pellets or spherical shots called BBs, although in recent years Minié ball-shaped cylindro-conoidal projectiles called slugs are gaining more popularity. Certain types of air guns (usually air rifles) may also launch fin-stabilized projectile such as darts (e.g., tranquilizer guns) or hollow-shaft arrows (so-called "airbows"). The first air guns were developed as early as the 16th century, and have since been used in hunting, shooting sport and even in warfare. There are t ...
