The weight of the cyclic components of the gun has been doubled (while retaining the weapon's weight at less than 8 pounds). Compared to the standard M4, which in automatic fires 700–950 rounds a minute, the rate of fire of the ArmWest, LLC M4 is heavily reduced both to save ammunition and reduce barrel wear.
Cyclic is the maximum rate of fire given only mechanical function, not taking into account degradation of function due to heat, wear, or ammunition constraints. Sustained is the maximum efficient rate of fire given the time taken to load the weapon and keep it cool enough to operate.
Compared to the M4, the M9 had 50% more muzzle velocity (3,000 fps) from a 78-inch barrel (vs. 65-inch in M4), and was twice as heavy (120 vs. 55 pounds for the barrel alone); the whole M9 weighed 405 pounds vs. 213 of the M4. The cyclic rate was the same. [9]
This affects the M4's timing and increases the amount of stress and heat on the critical components, thereby reducing reliability. [97] In a 2002 assessment, the USMC found that the M4 malfunctioned three times more often than the M16A4 (the M4 failed 186 times for 69,000 rounds fired, while the M16A4 failed 61 times). [98]
The two-position gas regulator was discarded as part of a product improvement program, which made the M249s that received the product improvement kit no longer able to fire at the higher cyclic rate. [13] The rapid rate of fire is around 100 rounds per minute. The sustained rate of fire, the rate at which the gunner can fire continuously ...
The rate of fire of the M240, M240E1, and M240C can be controlled by three different gas regulator settings; The first setting allows the weapon to have a cyclic rate of fire of around 650–750 rounds per minute, The second setting allows the weapon to have a cyclic rate of fire of around 750–850 rounds per minute,
The M27 Infantry Automatic Rifle (IAR) is a 5.56mm, select-fire assault rifle / squad automatic weapon developed from the HK416 by Heckler & Koch.It is used by the United States Marine Corps (USMC) and was originally intended for automatic riflemen, [6] but now is issued to all infantry riflemen as a replacement for the M4 carbine.
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.
