Machine Gun News: The Magazine for Full-Auto Enthusiasts; Volume 6, No. 6, November 1992

The format is approximately 8.25 inches byn 11 inches. 60 pages, including covers. Illustrated covers. Illustrations. Tabular Data. Among the topics covered are: Scattergun Technologies, Bill Vallerand, MP41 Submachine Gun, Larand.22 Suppressor, Browning automatic Rifle 1918A2, BAR, TREXPO, Al Paulson, Dan Shea, Noel Napolilli, Dick Morin, Shawn Daniel, Robert Hausman. This publication was prominent during the 1990s but from all available information has ceased publication and does not appear to have been merged into a successor publication. Dan Shea became the founder of the firearms research magazines Small Arms Review, Small Arms Defense Journal, and the training/supply company Phoenix Defense (formerly Long Mountain Outfitters) . He was a recipient of the much respected Chinn Award, thereby honoring "a government or industry individual who, in the opinion of the Small Arms Committee Executive Board, has made significant contributions to the field of small arms and/or infantry weapons systems".The award is only given out once a year and the recipients almost read like a who’s who of Infantry small arms design and innovation or contributing research. Robert Hausman was employed in publishing and wrote articles and edited the trade magazines,Machine Gun News, New Firearms Business and the International Firearms Trade, for many years. He owned two gun businesses. He was a member of the NRA. A machine gun (MG) is a fully automatic and rifled firearm designed for sustained direct fire. Automatic firearms of 0.79 inches caliber or more are classified as autocannons rather than machine guns. As a class of military kinetic projectile weapons, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoil. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general-purpose machine guns, and squad automatic weapons. Unlike semi-automatic firearms, which require one trigger pull per round fired, a machine gun is designed to continue firing for as long as the trigger is held down. Nowadays, the term is restricted to relatively heavy crew-served weapons, able to provide continuous or frequent bursts of automatic fire for as long as ammunition feeding is replete. Machine guns are used against infantry, low-flying aircraft, small boats and lightly/unarmored land vehicles, and can provide suppressive fire (either directly or indirectly) or enforce area denial over a sector of land with grazing fire. They are commonly mounted on fast attack vehicles such as technicals to provide heavy mobile firepower, armored vehicles such as tanks for engaging targets too small to justify the use of the primary weaponry or too fast to effectively engage with it, and on aircraft as defensive armament or for strafing ground targets, though on fighter aircraft true machine guns have mostly been supplanted by large-caliber rotary guns. Some machine guns have in practice sustained fire almost continuously for hours; other automatic weapons overheat after less than a minute of use. Because they become very hot, the great majority of designs fire from an open bolt, to permit air cooling from the breech between bursts. They also usually have either a barrel cooling system, slow-heating heavyweight barrel, or removable barrels which allow a hot barrel to be replaced. Although subdivided into "light", "medium", "heavy" or "general-purpose", even the lightest machine guns tend to be substantially larger and heavier than standard infantry arms. Medium and heavy machine guns are either mounted on a tripod or on a vehicle; when carried on foot, the machine gun and associated equipment (tripod, ammunition, spare barrels) require additional crew members.
