no
The rate of fire may be anywhere from 200 to 6,000 shots per minute, depending on the gun. There is no one rate of fire for all machine guns.
depends on what kind it is
YES. It is accurate and has a great fire rate.
The "Potato Digger" was not the slowest rate of fire weapon. The French Chauchat machine gun fired 240 rounds per minute
Yes, in general a suppressor can increase rate of fire by 50-100 rounds/ minute.
Usually the voltage level of your gun's battery defines the rate of fire. There is also different motors in airsoft guns.
The 7.62 mm gun (The Army calls it the M134) has 3 different rates of fire. When used a a fixed weapon, the rate is 6000 rds per minute. When used as a crew served weapon, rate is switchable between 2000 and 4000 rpm.
Keep it clean and get a stronger spring.
Depends on the outside temperature and rate of fire.
Fully automatic firearms (machineguns) truly have a rate of fire, as they continue to fire as long as the trigger is held down. Semi-auto, pump, bolt and lever firearms fire one shot, and will either reload, or are reloaded by the shooter manipulating the gun's action. A single shot firearm must be loaded by hand, and would be the slowest of conventional firearms. The absolute slowest rate of fire would be a flintlock rifle, which has a rate of fire by a skilled rifleman of about 2 shots per minute.
It depends on the make/model of the gun, and the power source (AEG, CO2, green gas, as spring ones require to be cocked after each shot.)
A Tommy gun, or Thompson submachine gun, typically fires at a rate of around 600 to 1,200 rounds per minute, depending on the model and configuration. The most common variants, like the M1928, have a cyclic rate of about 600 rounds per minute. This high rate of fire made the Tommy gun notorious during the Prohibition era and in various conflicts.
