MM-1
The MM-1 is a 40x46mm semi-automatic grenade launcher manufactured during the 1980s in the United States by the Hawk Engineering Company from Lake Bluff, Illinois. Development The Hawk MM-1 was adapted from the Manville machine projector, a revolver-type 18-shot tear gas gun, developed in USA for police use before the Second World War. Michael Rogak upsized the Manville design to 40mm and made certain design changes. One innovation was Rogak's development of a button rifling procedure for the aluminum barrel. This increased the speed of production while reducing costs. Subsequently, Rogak and a few others formed Hawk Engineering and began production of the MM-1. Operation The MM-1 is a revolver-type weapon, with the heavy cylinder being rotated for each shot by the clockwork-type spring. The cylinder could hold up to 12 rounds. The spring is wound manually during the reloading. It can accept any 40 mm grenade of up to 101 mm length. To reload the cylinder, the rear part of t ...

Manville Gun
The Manville gun was a stockless, semi-automatic, revolver type gun, introduced in 1935 by Charles J. Manville.Machine Projector United States Patent US2101148. Applied for in March 11, 1935 and granted in December 7, 1937. The Manville Gun was a large weapon, with a heavy cylinder being rotated for each shot by a clockwork-type spring. The spring was wound manually during the reloading. By 1938 Manville had introduced three different bore diameter versions of the gun, based on 12-gauge, 25-mm, or 37-mm shells. Due to poor sales, Manville guns ceased production in 1943. Manville 12-Bore Gun The original, 1935, steel-and-aluminum weapon held twenty-four rounds of 12-gauge × 2.75-inch (18.5×70mmR) shells in a spring-driven rotary-cylinder that had to be wound counter-clockwise before firing. It consisted of a steel barrel of , a rotating aluminum-alloy ammo cylinder, a single-piece steel body and foregrip, and wooden pistol grips. Loading and unloading were effected by uns ...

Grenade Launcher
A grenade launcher is a weapon that fires a specially designed, large caliber projectile, often with an explosive, Smoke screen, smoke, or tear gas, gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade Cartridge (firearms), cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces. Grenade launchers are produced in the form of standalone weapons (either Single-shot, single shot or Repeating firearm, repeating) or as attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 grenade launcher, Mk 19 are mounted on Weapon mount, tripods or vehicles. Some armored fighting vehicles also mount fixed arrays of short-range, single-shot grenade launchers as a means of defense. History Early precursors The earliest devices that could ...

Lake Bluff, Illinois
Lake Bluff (formerly Rockland) is a village in Lake County, Illinois, United States. Per the 2020 United States census, 2020 census, the population was 5,616. History The first settler family to claim land within the area now part of Lake Bluff arrived in 1836. They claimed 100 acres of land extending from the lake west to the Green Bay Trail. In 1849, a few residents left to seek their fortune in the California gold rush. In 1837, William and Mary Dwyer claimed the land just north of the former Central School. They opened and operated a stage coach stop and tavern along the Green Bay Trail. Some of the other early settlers were Henry and Angeline Ostrander, James Cole and William Whitnell. In 1855, the first railroad through Lake County was completed, running from Chicago through the county line. Henry Ostrander owned the land where the depot was to be placed, and he agreed to donate the site if the depot were called "Rockland." Therefore, this area, known previously as th ...

American Rifleman
''American Rifleman'' is a United States–based monthly shooting and firearms interest publication, owned by the National Rifle Association of America (NRA). It is the 33rd-most-widely-distributed consumer magazine and the NRA's primary magazine. The magazine has its headquarters in Fairfax, Virginia. History Arthur Corbin Gould, an avid shooter and member of the Massachusetts Rifle Association, published ''The Rifle'' in 1885 as an effort to focus discussion on the sport of rifle shooting. ''The Rifle'' later changed its title to ''Shooting and Fishing'' in 1888, branching out into other outdoor sports. In 1894, while the magazine was titled ''Shooting and Fishing'', Gould attended the National Rifle Association matches held at Sea Girt and was impressed with the level of competition, leading him to write several editorials urging the public to join. This call eventually led to the revitalization of the NRA and established a board of directors to help manage the nationwi ...

Rifling
Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves. The opposite of rifling is smoothbore. Rifling is measured in ''twist rate'', the distance the rifling takes to complete one full revolution, expressed as a ratio with 1 as its base (e.g., 1:). A shorter distance/lower ratio indicates a faster twist, generating a higher spin rate (and greater projectile stability). The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it: barrels intended for short, large-diameter projectiles such as spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm). Barrels intended for long, small-diameter projectiles, such as the ultra-low-drag 80-grain 0.223 inch bullets (5.2 g, 5.56&nb ...

40 Mm Grenade
This is a general collection of the world's many types of ammunition for grenade launchers in caliber. Several countries have developed or adopted grenade launchers in 40 mm caliber. NATO NATO currently uses three standardized 40 mm grenade families: 40 mm low velocity (LV), 40 mm medium velocity (MV), and 40 mm high velocity (HV). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers. 40×46 mm LV (40 mm low velocity) ''40×46 mm LV'' (''low velocity'') is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, Heckler & Koch AG36 and M320 Grenade Launcher Module. The propellant has low pressure and gives the projectile an average velocity of depending on the ammunition type. 40 mm low-velocity ammunition types (NATO) Besides combat ammo there also exists crowd control a ...

This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems.

Christianity considers the Second Coming of Jesus Christ to entail the final judgment by God of all people who have ever lived, resulting in the salvation of a few and the damnation of many. Some Christian denominations believe most people will be saved, some believe most people will be damned, and some believe the number of the saved and of the damned is unknown. The concept of the Last Judgment is found in all the canonical gospels, particularly in the Gospel of Matthew. The Christian tradition is also followed by Islam, where it is mentioned in many chapters of the Quran, according to some interpretations.
