Iron sights

+ Save concept

Iron sights are a system of shaped alignment markers (usually metal) used as a sighting device to assist in the aiming of a device such as a firearm, crossbow, or telescope, and exclude the use of optics as in reflector (reflex) sights, holographic sights, and telescopic sights. [1]

M16 rifle

The M16 rifle, officially designated Rifle, Caliber 5.56 mm, M16, is a United States military adaptation of the ArmaLite AR-15 rifle.Kern, Danford Allan (2006).. m-14parts.com. A thesis presented to the Faculty of the US Army Command and General Staff College in partial fulfillment of the requirements for the degree MASTER OF MILITARY ART AND SCIENCE, Military History. Fort Leavenworth, KansasKokalis, Peter G.. Nodakspud.com The original M16 was a selective fire 5.56mm rifle with a 20-round magazine. In 1964, the M16 entered U.S. military service and the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the U.S. military's standard service rifle.Ezell, Edward Clinton (1983). Small Arms of the World. New York: Stackpole Books. pp. 46–47..Urdang, p. 801. The M16A1 improvements include a bolt-assist, chrome plated bore and a new 30-round magazine. In 1983, the U.S. Marine Corps adopted the M16A2 rifle and the U.S. Army adopted it in 1986. The M16A2 fires the improved 5.56×45mm NATO (M855/SS109) cartridge and has a new adjustable rear sight, case deflector, heavy barrel, improved handguard, pistol grip and buttstock, as well as a semi-auto and three-round burst only fire selector. Adopted in 1998, the M16A4 is the fourth generation of the M16 series.Weapons of the Modern Marines, by Michael Green, MBI Publishing Company, 2004, page 16 It is equipped with a removable carrying handle and Picatinny rail for mounting optics and other ancillary devices. 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 5.56 mm caliber. The U.S. Military has largely replaced the M16 in combat units with a shorter and lighter version named the M4 carbine.
