Air-cooled machine guns normally attribute fast-improve barrels (generally carried by a crew member), passive cooling fins, or in some designs pressured-air cooling, like that used with the Lewis Gun. Developments in metallurgy and usage of Specific composites in barrel liners permit for bigger heat absorption and dissipation during firing. The upper the rate of fireplace, the more often barrels need to be altered and permitted to neat. To attenuate this, most air-cooled guns are fired only In a nutshell bursts or in a diminished price of fireplace. Some patterns – including the a lot of variants of the MG42 – are effective at prices of fireplace in extra of one,200 rounds per moment.
In addition they usually have either a barrel cooling program, gradual-heating heavyweight barrel, or detachable barrels which permit a scorching barrel to be replaced.
