Airsoft Machine Gun Styles
Almost all Airsoft Machine guns are generally referred to as LMGs, which stands for Light Machine Guns. However, this is a misnomer, as not all Airsoft Machine Guns are Light Machine Guns. Some airsoft Machine Guns are actually Medium Machine Guns or more specifically referred to as General-Purpose Machine Guns or GPMGs such as the M60 family, which are Medium Machine Guns. There are also Squad Automatic Weapons (SAWs), such as the M249 family, which are Light Machine Guns (LMG). There are also LMGs, that are based off an M4/M16 but use a belt fed upper receiver conversion, while these are called LMGs, they aren’t exactly the same as the other Airsoft Machine Guns. Are you confused yet?
The most important thing to keep in mind is that true airsoft machine Guns, whether they are LMGs, GPMGs, or SAWs, is that they use a specially designed gearbox, which is heavily reinforced for high volumes of sustained fire. The M4/M16 types, briefly mentioned above, use a standard Version 2, M4 style Gearbox, which is susceptible to failure when subjected to the volume of fire that typical airsoft machine guns are subjected to. A true airsoft machine gun gearbox can handle the stress without the actual gearbox shell failing. The internal parts are mostly unchanged, which is good for being able to tune, upgrade, and repair the gun, but the gearbox shell uses SUBSTANTIALLY larger bearings for the gears that can handle a much higher load and prolonged, sustained rotation. Most of the true Airsoft Machine Gun gearboxes use a quick change spring guide, which will allow you to adjust your velocity, quickly, and easily with a standard AEG Style Upgrade Spring. This is very useful, and often an under appreciated feature, as some fields will have a field limit of 1.5 Joules tested with a .32g BB, like our field FAF Airsoft, while some indoor fields will have a velocity requirement of 400 FPS with .20g BBs, and some larger national airsoft operations will sometimes allow certain machine guns to have a higher velocity of 450 FPS with .20g BBs. Airsoft Machine guns will use an electric, battery powered, automatically winding box magazine. The magazine needs to be initially “primed” with BBs before you can start firing, but after the initial “priming” of the magazine, you can fire the entire box magazine's contents (typically 2,500 rounds) in one, long, pull of the trigger. Electric box/drum magazines are available for standard M4/M16 variants as well if you want some serious firepower. A lot of these magazines will automatically keep winding themselves to keep BBs feeding by one of 3 means, typically there is a pressure switch that you can squeeze to wind up the magazine. There is also a sound activation mode which will wind the magazine up when it hears the gun firing. The last common one is pressure sensitive, it senses when the BBs back up in the feeding top and stops winding. When you start firing again, it will start feeding the BBs. Another less common method is similar to the first one, where a switch or circuit is completed when the trigger is pulled. Some people will wire their gun’s box magazines to the trigger switch. This all sounds great so far doesn’t it? For the most part, the only weak link in the puzzle is the magazine’s feeding tube, which is usually a steel coil/spring, that is flexible enough to make a sharp bend from the magazine into the gun. The only downside is if the end user isn’t careful removing the box magazine from the gun, they can stretch out the spring, or put a kink in the feeding tube.
