The tripod mount, designed by L. V. Stepanov for the PKM machine gun entered service in 1969. The Stepanov tripod mount is almost entirely made from stamped steel and weighs 4.5 kg (9.92 lb). It is lighter and has 20 fewer components than the preceding Samozhenkov tripod; its production is 40% less labour-intensive; and its design does not ...

The M192 Lightweight Ground Mount is a tripod fielded by the United States armed forces. It was designed and developed by Capco, Incorporated under contract through Picatinny Arsenal to replace the M122 tripod. [1] The United States Army named the tripod one of 2005's top ten inventions. [1] It was designed for use with the M249, M240B, and M240L.
When Hiram Maxim developed his recoil-powered machine gun that used a single barrel, the first main design was a modest 26 pounds (11.8 kg) in weight, firing a .45-inch rifle caliber bullet (from a 24 inch long barrel). As depicted in a famous photo of Maxim, it could be picked up complete with its 15-pound (6.8 kg) tripod with one arm.
The weight has been reduced to 9.27 kg (20.4 lb), 2.23 kg (4.9 lb) lighter than the M/62. Its rate of fire of around 500–650 rounds per minute (RPM) [ 31 ] is significantly less than the Danish M/62's 1,200 RPM, but it allows for better control, greater accuracy, more conservation of ammunition, more versatile firing positions, and less risk ...
The process capability index, or process capability ratio, is a statistical measure of process capability: the ability of an engineering process to produce an output within specification limits. [1] The concept of process capability only holds meaning for processes that are in a state of statistical control. This means it cannot account for ...
On MG 3 machine guns, two types of bolts are available, with standard weight (about 650 g (22.93 oz)) for the standard 1,000–1,200 rounds per minute cyclic rate of fire [17] and with extra weight (about 900 g (31.75 oz)) for a slower 800–950 rounds per minute cyclic rate of fire.
The Kord-12.7 mm heavy machine gun is a Russian design that entered service in 1998 [3] replacing the older NSV machine gun.Externally the weapon resembles the NSV; however, the internal mechanism has been extensively reworked, changing from a horizontally pivoting breech block to a rotating bolt design.
