Johnston Model D1918 Machine Gun
The Johnston Model D1918 was a light machine gun. It is a rare and little-known weapon with scant information available on it. It is best known for its resemblance to the Lewis Gun, having a similar gas-operated action and a barrel surrounded by a cooling shroud. The weapon was chambered for the .30-06 round, fed from double drum magazines.Rather than the Lewis pan magazine. The action was gas-operated, with the piston working in a cylinder beneath and integral with the barrel. The Johnston did not use the Lewis's prominent clock spring. Cocking of the piece was unusual, the entire pistol grip sliding forwards to engage the action, then returning backwards to cock it.A similar cocking action was used in the Czech BESA 15mm and was copied for later models of the Besal emergency production LMG based on the Bren This was first unlocked by a trigger-like mechanism in a cutout through the grip, behind the firing trigger. The cooling shroud could be removed without tools by uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Machine Gun
A light machine gun (LMG) is a light-weight machine gun designed to be operated by a single infantryman, with or without an assistant, as an infantry support weapon. LMGs firing cartridges of the same caliber as the other riflemen of the same combat unit are often referred to as squad automatic weapons. Characteristics While early light machine guns fired full-powered rifle cartridges, modern light machine guns often fire smaller-caliber rifle cartridges than medium machine guns – generally the same intermediate cartridge fired by a service's standard assault rifle – and are usually lighter and more compact. Some LMGs, such as the Russian RPK, are modifications of existing designs and designed to share the same ammunition. Adaptations to the original rifle generally include a larger magazine, a heavier barrel to resist overheating, a more robust mechanism to support sustained fire and a bipod. A light machine gun is also defined by its usage as well as its specificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30-06 Springfield
The .30-06 Springfield cartridge (pronounced "thirty-aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. The ".30" refers to the caliber of the bullet in inches. The "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. It remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1901, the U.S. started developing an experimental rimles ...

Double Drum Magazine
A drum magazine is a type of high-capacity magazine for firearms. Cylindrical in shape (similar to a drum), drum magazines store rounds in a spiral around the center of the magazine, facing the direction of the barrel. Drum magazines are contrasted with more common box-type magazines, which have a lower capacity and store rounds flat. The capacity of drum magazines varies, but is generally between 50 and 100 rounds. History and usage 1800s The first drum magazine was patented in 1853 by Charles N. Tyler. 1900s Pistols and rifles A drum magazine was built for the Luger (Pistole 1908) pistol; although the Luger usually used an 8-cartridge box magazine, the optional 32-cartridge ''Schneckenmagazine'' ("snail magazine") was also sometimes used. Moubray G. Farquhar and Arthur H. Hill applied for a British patent for "A New or Improved Cartridge Magazine for Small Arms and Machine Guns" in 1915 for their Farquhar–Hill rifle, and it was accepted in 1919.
