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.

SIG SG 550
The SG 550 is an assault rifle manufactured by Swiss Arms AG (formerly a division of Schweizerische Industrie Gesellschaft, now known as SIG Holding AG) in Switzerland. "SG" is an abbreviation for ''Sturmgewehr'' ("assault rifle"). The rifle is based on the earlier 5.56×45mm NATO SIG SG 540. History Development In 1978, the Swiss armed forces formulated requirements for a successor to the Stgw 57 battle rifle (known commercially as the SG 510) using the 7.5×55mm GP 11 cartridge. Emphasis was placed on modularity; the weapon family was to include several variants of the base design, including a compact carbine that would be issued to rear-echelon and support troops, command staff, vehicle crews, special forces personnel and paratroopers. Another aim was to reduce the overall weight of the rifle while retaining comparable or improved accuracy out to 300 m. The solicitation was narrowed down to two designs: the W+F C42 (developed by the state-owned Waffenfabrik Bern, using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SA80
The SA80 (Small Arms for the 1980s) is a British family of 5.56×45mm NATO service weapons used by the British Army. The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle. The first prototypes were created in 1976, with production of the A1 variant starting in 1985 and ending in 1994. The A2 variant came to be as the result of a significant upgrade in the early 2000s by Heckler & Koch and remains in service as of 2020.

PVAR Rifle
UDMC PVAR rifles are Filipino variants of the Armalite AR-15 and AR-10 using the Pneumatic Valve and Rod system manufactured by United Defense Manufacturing Corporation. The Pneumatic Valve and Rod system was created to be a more reliable alternative to the Stoner bolt and carrier piston system used in the AR-15 family, commonly but incorrectly referred to as a direct impingement system. History United Defense Manufacturing Corporation undertook the development of the rifle as a possible replacement for traditional AR-15 designs. Philippine Letters of Patent Nos. 1-2009-000176 and 1-2011-000062 were issued in 2009 and 2011, respectively. A PVAR rifle was featured in a September 2011 issue of the Baltimore Gun Club magazine held by a representative of the Seattle Sounders.

M4 Carbine
The M4 carbine (officially Carbine, Caliber 5.56 mm, M4) is a 5.56×45mm NATO, gas-operated, magazine-fed carbine developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle. The M4 is extensively used by the United States Armed Forces, with decisions to largely replace the M16 rifle in United States Army (starting 2010) and United States Marine Corps (USMC) (starting 2016) combat units as the primary infantry weapon and service rifle. The M4 has been adopted by over 60 countries worldwide, and has been described as "one of the defining firearms of the 21st century". Since its adoption in 1994, the M4 has undergone over 90 modifications to improve the weapon's ergonomics and modularity, including: the M4A1, which strengthened the barrel and removed the burst-fire option; the SOPMOD, an accessory kit containing optical attachments; and the underbarrel M203 grenade launcher. In April 2022, the U.S. Army selected the SIG MCX SPEAR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heckler & Koch XM8
The Heckler & Koch XM8 is a lightweight assault rifle system developed from the late 1990s to early 2000s. The rifle was designed by German small arms manufacturer Heckler & Koch (H&K), and shares design and engineering with their G36 rifle. The XM8 design was originally part of the Objective Individual Combat Weapon program (OICW), which was developing a "smart" grenade launcher system with an underslung carbine rifle. The system was unable to meet performance and weight requirements and was eventually canceled. In the aftermath, the two portions of the OICW were separated, resulting in the XM8 and XM25 projects. While the XM8 was being considered by the United States Army as a potential standard infantry rifle, to replace the M4 carbine, this project was put on hold in April 2005, and was formally canceled on October 31 of that year. The weapon was adopted by the Royal Malaysian Navy for its PASKAL special forces. History The U.S. Army's purpose in contracting for this p ...

Heckler & Koch HK43
The Heckler and Koch HK43 is a civilian semi-automatic rifle based upon the Heckler & Koch HK33 rifle and is the predecessor of the Heckler & Koch HK93 semi-automatic rifle. Overview The HK43 was created in 1974 as a semi-automatic version of the HK33 (which itself was a scaled down version of the Heckler & Koch G3, but chambered for 5.56×45mm NATO). According to H&K’s numbering nomenclature, the “4” indicates that the weapon is a paramilitary rifle, and the “3” indicates that the caliber is 5.56 mm. The HK40-series was designed for sale to conscripts so they could be familiar with their service rifle before entering military service, a common practice in Germany and Switzerland. They had a bayonet mount and furniture just like the military model, but came with a semi-auto trigger pack instead of a full auto trigger pack. This allowed a civilian rifle to be easily made into an assault rifle just by dropping in a full auto trigger pack. HK43 can sell for anywhere be ...

Heckler & Koch HK416
The Heckler & Koch HK416 is a gas-operated assault rifle chambered for the 5.56×45mm NATO cartridge. It is designed and manufactured by the German company Heckler & Koch. Although the design is based on the AR-15 class of firearm (specifically the Colt M4 carbine family issued to the U.S. military), it uses a proprietary short-stroke, gas piston system from Heckler & Koch's earlier G36 family of rifles. The HK416 is the standard assault rifle of the Norwegian Armed Forces, and it has been selected by the French Armed Forces to replace the FAMAS. Other users of the HK416 include the German Army and the Irish Army Ranger Wing, as well as the US Navy's SEAL Team Six, who used it to kill Osama Bin Laden in 2011. History The United States Army's Delta Force, at the request of R&D NCO Larry Vickers, collaborated with Heckler & Koch to develop a new carbine in the 1990s for use in close quarters combat. At this point, they were equipped with the Heckler & Koch MP5, whose 9mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heckler & Koch HK33
The Heckler & Koch HK33 is a 5.56mm assault rifle developed in the 1960s by West German armament manufacturer Heckler & Koch GmbH (H&K), primarily for export. Building on the success of their G3 design, the company developed a family of small arms (all using the G3 operating principle and basic design concept) consisting of four types of firearms: the first type, chambered in 7.62×51mm NATO; the second, using the Soviet 7.62×39mm M43 round; the third, chambered in .223 Remington and 5.56×45mm NATO; and the fourth type, chambered for the 9×19mm Parabellum pistol cartridge. Commercially the HK33 was a successful design but it did not sell as well as the G3. The HK33 series of rifles were adopted by the Brazilian Air Force (''Força Aérea Brasileira'' or FAB), the armed forces of Thailand and Malaysia where they were produced under a licence agreement. The rifle was also licence-built in Turkey by MKEK, and exported from France branded as MAS but actually made in Germany ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heckler & Koch G36
The Heckler & Koch G36 (Gewehr 36) is a 5.56×45mm assault rifle designed in the early 1990s by German weapons manufacturer Heckler & Koch as a replacement for the heavier 7.62×51mm G3 battle rifle. It was accepted into service with the ''Bundeswehr'' in 1997, replacing the G3.Woźniak, Ryszard. Encyklopedia najnowszej broni palnej – tom 2 G-Ł. Bellona. 2001. pp17-21. Since then, it has also been a popular export, and the G36 has seen active service in military and police units in several countries, including Germany, Spain, and the United Kingdom. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine. In 2012, the G36 was found to suffer from severe accuracy problems when the weapon overheated which prompted the search for a replacement. In 2017, the ''Bundeswehr'' launched the ''System Sturmgewehr Bundeswehr'', a program to find a replacement for the G36. The weapons put forth were the Heckler & Koch HK416, Heckler & ...
