The '''CompM2''' is a battery-powered, non-magnifying [[Red dot sight|red dot]] type of [[Reflector sight|reflex sight]] for [[firearm]]s manufactured by [[Aimpoint AB]]. It was first introduced in the [[United States Armed Forces|U.S. Armed Forces]] in 2000,<ref>{{cite web |title=CompM2 |url=https://www.aimpoint.com/products/discontinued/compm2-4-moa-red-dot-reflex-sight |website=Aimpoint |access-date=25 June 2021}}</ref> designated as the '''M68 Close Combat Optic''' (M68 CCO; [[NATO Stock Number|NSN]]: 1240-01-411-1265). It is also known as the ''M68 Aimpoint'' and is designed to meet [[United States Military Standard|United States military standards]]. The sight is designed for use with the [[M16 rifle|M16]]/[[M4 carbine|M4]] family of rifles, but can be mounted on any weapon fitted with an upper [[Picatinny rail]]. It is also [[Night vision device|NVG]]-compatible—the aiming dot is still visible through [[night vision]] [[telescopic sight|scopes]] and [[Night vision device|goggles]]. The Army's M68 designation was also applied to a later version of the sight, the [[Aimpoint CompM4]].

==Overview==
The M68 is [[parallax]]-free at around 45.7 m (50 yards), meaning that the red dot will not change position based on eye position at that range.<ref>[http://www.globalsecurity.org/military/library/policy/army/fm/3-22-9/c08.htm Army Field Manual FM 3-22.9, Chapter 8]. www.globalsecurity.org. Retrieved  8 March 2011</ref> At shorter ranges the point of aim will change position based on eye position with the maximum error being equal to the radius of the sight's optical window at short range.<ref>{{Cite web|url=http://www.bullseyepistol.com/dotsight.htm|title=Encyclopedia of Bullseye Pistol|website=www.bullseyepistol.com}}</ref> The sight is water-tight down to 25 meters and runs on one 3-[[volt]] [[lithium battery]] type 2L76 or DL1/3N. Aiming dot brightness is adjustable for better visibility or increased battery life.

The CompM2 is used across branches of the [[United States Armed Forces|U.S. Armed Forces]], [[Swedish Armed Forces|Sweden]], and various [[NATO]] countries, among them [[Norwegian Armed Forces|Norway]]. A variant known as the ECOS-N (NSN: 1240-01-495-1385) is also issued as part of the U.S. [[SOPMOD]] kit. The sight is also available on the civilian market and is employed by various [[law enforcement]] organizations (especially for SWAT type situations that involve close quarters work) and by recreational shooters.

By August 2011, the U.S. Army had bought 1,000,000 M68 Close Combat Optics.  Some 85 percent of Army M4s are issued with the CCO, though optics can vary depending on unit.  The sight allows soldiers to engage targets out to 300 meters while keeping both eyes open for situational awareness.  Post combat surveys show an 85 percent acceptance rate of the CCO as an effective optic and for its value for close quarters fighting.<ref>{{cite web|url=http://usarmy.vo.llnwd.net/e2/c/downloads/215919.pdf |title=Archived copy |accessdate=2013-10-26 |url-status=dead |archiveurl=https://web.archive.org/web/20140528190514/http://usarmy.vo.llnwd.net/e2/c/downloads/215919.pdf |archivedate=2014-05-28 }}</ref>

In July 2009, the Army purchased 565,783 [[Aimpoint CompM4]] sights (a later version of the CompM2), as part of the M68 CCO program.<ref name="compm4 is new m68">{{cite web |last1=Gourley |first1=Scott R. |title=Soldier Armed M68 Close Combat Optic |url=https://www.ausa.org/sites/default/files/Soldier%20Armed.pdf |website=AUSA |access-date=29 June 2022 |archive-url=https://web.archive.org/web/20220523221427/https://www.ausa.org/sites/default/files/Soldier%20Armed.pdf |archive-date=23 May 2022 |date=April 2010}}</ref>
