This can 3 shot a normal zombie, so if they are jumping, kick them down and shoot them to conserve ammo. Accuracy is decent but has a long reload time.

Wikipedia Information

The M16 rifle, officially designated Rifle, Caliber 5.56 mm, M16, is the United States military select-fire adaptation of the AR-15 rifle. The rifle was adapted for semi-automatic and full-automatic fire. Colt purchased the rights to the AR-15 from ArmaLite, and currently uses that designation only for semi-automatic versions of the rifle. The M16 fires the 5.56×45mm NATO cartridge. The rifle entered United States Army service and was deployed for jungle warfare operations in South Vietnam in 1963, becoming the U.S. military's standard service rifle of the Vietnam War by 1969, replacing the M14 rifle in that role. The U.S. Army retained the M14 in CONUS, Europe, and South Korea until 1970. In 1983 with the USMC's adoption of the M16A2 (1986 for the US Army), the M16 rifle was modified for three-round bursts, with some later variants having all modes of fire and has been the primary service rifle of the U.S. armed forces. The M16 has also been widely adopted by other militaries around the world. Total worldwide production of M16s has been approximately 8 million, making it the most-produced firearm of its caliber. As of 2010, the U.S. Army is supplementing the M16 in combat units with the M4 carbine, which is a smaller version of the M16.

  • In real life, some models of the M16 have burst, but it is capable of automatic fire.
  • The M16 is not widely used due to the 3 shot burst limitation and slightly fast ammo consumption.
