Rate of fire may also be affected by ergonomic factors. For rifles, ease-of-use features such as the design of the bolt or magazine release can affect the rate of fire. For artillery pieces, a gun on a towed mount can usually achieve a higher rate of fire than the same weapon mounted within the cramped confines of a tank or self-propelled gun ...
This enabled the rate of fire to reach up to 24 rounds per minute. Elevation was improved with the gun able to depress to −10 degrees. To protect the crew, a large metal shield was added. The M2 was the standard weapon by 13 May 1943. From the march it could fire from its wheels in three minutes, and from a fully emplaced position in seven ...

In 2021, there were 26,000 gun suicides and 21,000 gun homicides, together making up a sixth of deaths from external causes. Gun deaths make up about half of all suicides, but over 80% of homicides. [5] Gun deaths in 2021 rose to levels not seen since the 1990s, but remained below rates of the 1970s. [6]
The M2 has varying cyclic rates of fire, depending on the model. The M2HB air-cooled ground gun has a cyclical rate of 450–575 rounds per minute. [29] The early M2 water-cooled AA guns had a cyclical rate of around 450–600 rpm. [30] The AN/M2 aircraft gun has a cyclic rate of 750–850 rpm; this increases to 1,200 rpm for AN/M3 aircraft guns.
The M240G has three gas settings, allowing the machine gun to have a fire rate between 650 and 750 rounds per minute when set to the first gas setting, 750–850 rounds per minute at the second gas setting, and 850–950 rounds per minute at the third gas setting, whereas the M240B only has one setting, restricting the fire rate to between 550 ...
The Small Arms Survey 2017 [1] provides estimates of the total number of civilian-owned guns in a country. It then calculates the number per 100 people. This number for a country does not indicate the percentage of the population that owns guns, because single individuals can own multiple guns. See also Percent of households with guns by country.
