XM312
The XM312 is a heavy machine gun derived from the XM307 25 mm autocannon and chambered for the .50 BMG cartridge. It was designed in response to a request by the Military of the United States, U.S. military for a replacement for the aging M2 Browning heavy machine gun, and as a complement to the heavier XM307 Advanced Crew Served Weapon grenade launcher. It is capable of being converted quickly into an XM307 with a small number of parts and a few minutes of work at the unit level (and vice versa from the XM307). The Fiscal Year 2008 Appropriations bill awarded $10 million to General Dynamics for the XM307 and XM312. In May 2008 the United States Army, U.S. Army had awarded General Dynamics Armament and Technical Products (GDATP) a $9 million contract to develop a lightweight .50-caliber machine gun called the XM806 to supplement the Browning M2. The XM806 was canceled in 2012. The Army at present will continue buying new M2s and Mk 19s to replenish the current guns that are ...

50 BMG
The .50 Browning Machine Gun (.50 BMG, 12.7×99mm NATO and designated as the 50 Browning by the C.I.P.) is a caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous belt using metallic links. The .50 BMG cartridge is also used in anti-materiel rifles. A wide variety of ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower quality rounds. History In response to the need for new anti-aircraft weaponry during World War I, John Browning developed the .50 BMG. He wanted the ...

Heavy Machine Gun
A heavy machine gun (HMG) is significantly larger than light machine gun, light, medium machine gun, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require weapon mount, mounting onto a weapons platform to be operably stable or tactically mobility (military), mobile, have more formidable firepower, and generally Crew-served weapon, require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber (12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration (weapons), penetration and stopping ...

XM205 Tripod
The M205 Lightweight Tripod for Heavy Machine Guns is the replacement for the current M3 tripod in support of the M2 machine gun and Mk 19 grenade launcher used in the United States armed forces. The soldier will experience less weight burden with the M205 Lightweight Tripod than with the standard M3 Tripod (, including the pintle and T&E), and will be able to take advantage of the enhanced tripod's integrated traverse and elevation mechanism for quicker, more accurate target engagement. Not only is the M205 (34 lbs) lighter than the M3 by over 16 lbs (33%), it is stronger and provides a more stable (lower dispersion) firing platform than the M3. The M205 was first fielded by the 1st Armored Division in November 2013. In addition to being lighter than the M3, it has an integrated Traverse & Elevation (T&E) mechanism that can be operated with one hand for faster and more accurate engagement. The legs have spades to dig into dirt or sand to be a stable platform. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Recoil Operation
Recoil operation is an operating mechanism used to implement locked breech, autoloading firearms. Recoil operated firearms use the energy of recoil to cycle the action, as opposed to gas operation or blowback operation using the pressure of the propellant gas. The earliest mention of recoil used to assist the loading of firearms is sometimes claimed to be in 1663 when an Englishman called Palmer proposed to employ either it or gases tapped along a barrel to do so. However no one has been able to verify this claim in recent times, although there is another automatic gun that dates from the same year, but its type and method of operation are unknown. Recoil-operation, if it was invented in 1663, would then lay dormant until the 19th century, when a number of inventors started to patent designs featuring recoil operation; this was due to the fact that the integrated disposable cartridge (both bullet and propellant in one easily interchangeable unit) made these designs viable.

Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition. The most common ammo capacity typically carried on a man-portable weapon system vary from 50 to 300 rounds. Variants Feed strip 8mm Lebel feed strip on an M1914 ...

M145 Machine Gun Optic
The C79 Optical sight is a small arms telescopic sight. Elcan names it as the SpecterOS3.4x, but in Canadian service, it is typically referred to as the C79 or the C79A2. A variant, the M145 Machine Gun Optic is in use by the US military. It is 3.4×28, meaning 3.4x magnification, and a 28mm diameter objective lens. A tritium illuminated reticle provides for normal and low-light conditions sighting. It can be mounted to a variety of rifles and light machine guns using the M1913 Picatinny rail mounting system or the similar "Diemaco" rail system found on small arms produced by Diemaco/Colt Canada. It is manufactured by Elcan and can be found on military service weapons around the world. Similar rifle sights are the Sight Unit Small Arms, Trilux (SUSAT) and the Advanced Combat Optical Gunsight (ACOG). Use Adopted in 1989, the Elcan C79 is the primary sighting system for the small arms of the Canadian Forces and is mounted on the Diemaco C7 and C7A2 assault rifles, the C8 Carbi ...

XM806MachineGun
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 ...
