Gyrojet
The Gyrojet is a family of unique firearms developed in the 1960s named for the method of gyroscopically stabilizing its projectiles. Rather than inert bullets, Gyrojets fire small rockets called Microjets which have little recoil and do not require a heavy barrel or chamber to resist the pressure of the combustion gases. Velocity on leaving the tube was very low, but increased to around at . The result is a very lightweight and transportable weapon. Long out of production, today they are a coveted collector's item with prices for even the most common model ranging above $1,000. They are rarely fired; ammunition, when available at all, can cost over $100 per round. History Robert Mainhardt and Art Biehl joined forces to form MBAssociates, or MBA, in order to develop Biehl's armor-piercing rocket rounds. Originally developed in a .51 caliber, the cartridges were self-contained self-propelled rockets with calibers ranging from .49 and 6mm to 20mm. A family of Gyrojet weapons w ...

Murderers' Row (film)
''Murderers' Row'' is a 1966 American comedy spy-fi film starring Dean Martin as Matt Helm. It is the second of four films in the Matt Helm series, and is very loosely based upon the 1962 spy novel '' Murderers' Row'' by Donald Hamilton. Ann-Margret and Karl Malden co-star in this sequel to ''The Silencers''. Plot The film begins with a shot of the United States Capitol being destroyed. It is actually a scale model being used in the demonstration of a heliobeam weapon in the headquarters of the Bureau of International Government and Order ("BIG O"). BIG O is a secret organization with the goal of world domination that previously appeared in ''The Silencers''. With the aid of a mole, BIG O conducts a worldwide assassination campaign against various secret agents working for ICE (Intelligence Counter Espionage). Matt Helm fakes his own death in preparation for investigating the scheme undetected. Helm meets his boss, Mac, for a mission briefing. They watch a film showing Solari ...

Destructive Device
In the United States, a destructive device is a type of firearm or explosive device regulated by the National Firearms Act of 1934, revised by the Omnibus Crime Control and Safe Streets Act of 1968 and Gun Control Act of 1968. Examples of destructive devices include grenades, grenade launchers, artillery weapons, and firearms with a bore over one half of an inch (.50 inches or 12.7mm), excluding some rifles and most shotguns, both semi automatic and manually operated. While current federal laws allow destructive devices, some states have banned them from transfer to civilians. In states where banned, only law enforcement officers and military personnel are allowed to possess them. All National Firearms Act firearms including destructive devices, must be registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives. The definition of a "destructive device" is found in (f). The definition reads as follows: : (1) any explosive, incendiary, or poison gas, (A) bomb, (B) ...

Gun Control Act Of 1968
The Gun Control Act of 1968 (GCA or GCA68) is a U.S. federal law that regulates the firearms industry and firearms ownership. Due to constitutional limitations, the Act is primarily based on regulating interstate commerce in firearms by generally prohibiting interstate firearms transfers except by manufacturers, dealers and importers licensed under a scheme set up under the Act. The GCA was signed into law by President Lyndon B. Johnson on October 22, 1968, and is Title I of the U.S. federal firearms laws. The National Firearms Act of 1934 (NFA) is Title II. Both GCA and NFA are enforced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). GCA repealed the Federal Firearms Act of 1938, though many of its provisions were reenacted as part of the GCA, which revised the FFA and its predecessor, the National Firearms Act of 1934 (NFA). History The bill was initially prompted by the assassination of U.S. President John F. Kennedy in 1963. The President was shot and ki ...

Zamac
ZAMAK (or Zamac, formerly trademarked as MAZAK) is a family of alloys with a base metal of zinc and alloying elements of aluminium, magnesium, and copper. Zamak alloys are part of the zinc aluminum, zinc aluminium alloy family; they are distinguished from the other ZA alloys because of their constant 4% aluminium composition. The name ''zamak'' is an acronym of the German language, German names for the metals of which the alloys are composed: (zinc), , and (copper). The New Jersey Zinc Company developed zamak alloys in 1929. The most common zamak alloy is zamak 3. Besides that, zamak 2, zamak 5 and zamak 7 are also commercially used. These alloys are most commonly die cast. Zamak alloys (particularly #3 and #5) are frequently used in the spin casting industry. A large problem with early zinc die casting materials was zinc pest, owing to impurities in the alloys. Zamak avoided this by the use of 99.99% pure zinc metal, produced by New Jersey Zinc Company, New Jersey Zinc's us ...

The Man From U
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Matt Helm
Matt Helm is a fictional character created by American author Donald Hamilton (1916-2006). Helm is a U.S. government counter-agent, a man whose primary job is to kill or nullify enemy agents—not a spy or secret agent in the ordinary sense of the term as used in most spy thrillers. Helm appeared in 27 adventure/suspense novels by Hamilton, first published in 1960, and the character was later adapted into film, television and other media. The character and the series Published between 1960 and 1993, the 27 books in the series portrayed Helm, who acquired the code name "Eric" during his secret wartime assignments, as jaded, ruthless, pragmatic, and competent. The series was noted for its between-books continuity, which was somewhat rare for the genre. In the later books, Helm's origins as a man of action in World War II disappeared and he became an apparently ageless character, a common fate of long-running fictional heroes. The first book in the series, ''Death of a Citiz ...

You Only Live Twice (novel)
''You Only Live Twice'' is the eleventh novel and twelfth book in Ian Fleming's James Bond series of stories. It was first published by Jonathan Cape in the United Kingdom on 26 March 1964 and sold out quickly. It was the last Fleming novel published in his lifetime. It is the concluding chapter in what is known as the "Blofeld Trilogy" after '' Thunderball'' and '' On Her Majesty's Secret Service''. The story starts eight months after the murder of Tracy Bond, which occurred at the end of the previous novel, ''On Her Majesty's Secret Service''. James Bond is drinking and gambling heavily and making mistakes on his assignments when, as a last resort, he is sent to Japan on a semi-diplomatic mission. Whilst there he is challenged by the head of the Japanese Secret Service to kill Dr. Guntram Shatterhand. Bond realises that Shatterhand is Ernst Stavro Blofeld and sets out on a revenge mission to kill him and his wife, Irma Bunt. The novel deals on a personal level with the chang ...

45 ACP
The .45 ACP (Automatic Colt Pistol) or .45 Auto (11.43×23mm) is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun. The standard issue military .45 ACP round uses a 230-grain (14.9 g) round nose projectile that travels at approximately 830 feet per second (250 m/s) when fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of , compared to for both 9mm Parab ...

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254  mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...
