The M60 (formally the United States Machine Gun, Caliber 7.62 mm, M60) is a family of American general purpose machine guns firing 7.62x51mm NATO cartridges from a disintegrating belt of M13 links. There are several types of live ammunition approved for use in the M60, including ball, tracer, and armor-piercing rounds.

Introduced in 1957, it has served with every branch of the U.S military and still serves with other armed forces. Its manufacture and continued upgrade for military and commercial purchase continues into the 21st century though it has been replaced or supplemented in most roles by other designs, notably the M240 in U.S service.Contents [hide]

The M60 is a belt-fed machine gun that fires the 7.62 mm NATO cartridge commonly used in larger rifles. It is generally used as crew-served weapon and operated by a team of two or three men. The team consists of the gunner, the assistant gunner (A-gunner in military slang), and the ammunition bearer. The gun's weight and the amount of ammunition it consumes when fired make it difficult for a single soldier to carry and operate. The gunner carries the weapon and, depending on his strength and stamina, anywhere from 200 to 1000 rounds of ammunition. The assistant carries a spare barrel and extra ammunition, and reloads and spots targets for the gunner. The ammunition bearer carries additional ammunition and the tripod with associated traversing and elevation mechanism, if issued, and fetches more ammunition as needed during firing.

The basic ammunition load carried by the crew is 600 to 900 rounds and theoretically allows approximately two minutes of continuous firing at the maximum rate of fire. All crews carry more than the basic load, sometimes three or more times the basic amount.

The M60 can be accurately fired at short ranges from the shoulder due to its design. This was an initial requirement for the design and a hold-over in concept from the M1918 Browning Automatic Rifle. It may also be fired from the integral bipod, M122 tripod, and some other mounts.

M60 ammunition comes in a cloth bandoleer containing a cardboard box of 100 pre-linked rounds. The M60 changed from M1 link to the different M13 link, a change from the older link system with which it was not compatible. The cloth bandoleer is reinforced to allow it to be hung from the current version of the feed tray. Historically, units in Vietnam used B3A cans from C-rations packs locked into the ammunition box attachment system to roll the ammunition belts over for a straighter and smoother feed to the loading port to enhance reliability of feed. The later models changed the ammunition box attachment point and made this adaptation not possible.

GF60 is a faithful replica of the most famous machine gun of the XX. century - the American M60. In this case we are dealing with the E4 version, designed specifically for the U.S. special units. 

The replica was constructed almost entirely of metal - the only elements produced from ABS (high quality plastic) are the grips, front and pistol, the butt stock, and the magazine. Its structure is characterized by a considerable strength as well as appreciable weight - over 14 pounds. This is not a gun to run around with. But on the other hand - that's not what it was designed for. 

To manufacture this model, strengthened internal components, including metal cylinder head, reinforced heads and chrome-plated cylinder, piston, spring guide as well as equipped with the bearing were used. What we also have here are steel gears, in this case mounted on 8 mm bearings. 

The rifle is equipped with low-resistance wiring with MOSFET and, what's interesting - a potentiometer. Placed under the barrel, it allows you to regulate the rate of fire. During the tests, we could obtain any rate of fire from 320 to 630 RPM while using the stock battery. It is worth mentioning that the theoretical ROF of the original weapon was 550 RPM. 

What makes our offer different then that sold by our competition? Along with this high-quality replica, we deliver the highest quality covers for the magazine in two camouflages: olive green and MultiSpeck. The material used to produce it is CORDURA 1000D.

CORDURA is a professional fabric, made of polyamide and polyurethane sheathed with Teflon finishing. It is used to manufacture the most demanding tactical accessories, whose task is to withstand significant mechanical abuse and extreme weather. CORDURA meets the requirements of the biggest and most technologically advanced armies in the world – it's used to make i.e. tactical vests used by the U.S. Army and Marine Corps, as well as first-class travel backpacks or tactical and trekking boots. It's also characterized by high resistance to weather conditions - the outer fabric being coated with a layer of Teflon, which greatly increases its durability and water resistance. At the same time, due to its internal structure, the fabric is extremely lightweight. CORDURA 1000D is the most durable material in its category - over 100 times stronger than polyester.
