The vehicle-mounted variant of the MAG lacks a stock, bipod, carry handle, pistol grip, ejection port dust cover and a mount for optical sights. It does, however, have a new closed-type gas regulator. Depending on the weapon's employment, the machine gun can also be fitted with an extended charging handle linkage, standard trigger group (with a pistol grip), or a specialized trigger assembly with an electrically fired trigger.

The pintle-mounted aircraft model is fed from either the right- or left-hand side exclusively with the M13 belt. Thus configured, weapons typically lack standard iron sights and are equipped with electrically powered triggers.

The ''L7'' [[general-purpose machine gun]] is used by the [[British Army]].<ref>{{cite web |url=http://www.army.mod.uk/equipment/support-weapons/1463.aspx |title=General Purpose Machine Gun |publisher=Army.mod.uk |access-date=2011-06-24 |url-status=dead |archive-url=https://web.archive.org/web/20130110080630/http://www.army.mod.uk/equipment/support-weapons/1463.aspx |archive-date=2013-01-10 }}</ref> The ''L7'' and the related ''L8'' are license-built derivatives of the MAG. The official British Army designation for the current version is the ''L7A2 GPMG'' (General Purpose Machine Gun).

The L7 was adopted by the British forces as a replacement for the long-serving [[Vickers machine gun]] (in the medium role) and the [[Bren]] (in the light assault role), following trials in 1957. Built under license originally by Royal Small Arms Factory, Enfield Lock and currently by Manroy Engineering,<ref>{{cite web |title=The General Purpose Machine Gun |url=http://www.manroy.co.uk/manroy/GPMG.HTML |website=www.manroy.co.uk |access-date=10 November 2018 |archive-url=https://web.archive.org/web/20071016060326/http://www.manroy.co.uk/manroy/GPMG.HTML |archive-date=16 October 2007}}</ref> it serves in the British Army, the [[Royal Marines]] , the RAF Regiment and other services. There have been two main variants, the L7A1 and L7A2, developed for infantry use, with the L7A2 having superseded the earlier variant. Several other variants have been developed, notably the L8 (produced in the L8A1 and L8A2 versions), modified for mounting inside armoured vehicles (the L37 variant was developed for mounting on armoured vehicles). Although intended to replace the Bren entirely, that light machine gun (re-chambered for 7.62×51mm NATO and re-titled as the L4) continued in use in jungle terrain (especially in the Far East), where there was no requirement for the medium machine gun role, and with secondary units, until the adoption of the [[SA80|L86A1]] Light Support Weapon (LSW). The LSW was intended to replace both the L7 and the L4 in the light machine gun role, but dissatisfaction with the L86's sustained fire capabilities and reliability resulted in combat units continuing to utilize the L7 whenever possible (although neither it, nor its 7.62×51mm NATO ammunition was supposed to be issued to infantry platoons). The British Army, Royal Marines and RAF Regiment were issued with the L110A2 ([[FN Minimi|FN Minimi Para]]) to replace the LSW as the light section support or fire support weapon. This uses the same NATO-standard [[5.56×45mm NATO|5.56×45mm]] ammunition as the [[SA80|L85]] assault rifle. However a review of requirements led to the withdrawal of both the L110A2 LMG and L86A2 LSW from service in 2018, with the 7.62&nbsp;mm L7A2 resuming its place in the British Army infantry section. Other variants continue to be used in mounted roles on many British military vehicles, naval vessels and aircraft.

In 1961, the [[Royal Small Arms Factory]], Enfield (now [[BAE Systems]]) in the United Kingdom, undertook licence production of the MAG in the following versions: L7A2, L8A2, L37A2, L20A1 and the L43A1. These models all use the M13 ammunition belt.

The ''L7A2'', general-purpose machine gun, replaced the L7A1 in service with the [[British Army]]. Compared to the MAG Model 60-20, it features, among other minor changes, an improved feed mechanism, a 10-position gas regulator valve, a polymer butt-stock, a provision for 50 round belt-box and a bracket, used to mount optical day- and night-vision sights, mounted to the left side of the receiver. In the sustained fire role, the L7A2 can be mounted on the L4A1 tripod in conjunction with a C2A2 Support Weapons Sight or the sight unit used on the [[FGM-148 Javelin]] anti-tank missile system. Fired by a two-man team who are grouped in a specialist [[Heavy weapons platoon#British Army|Machine Gun Platoon]] the L7A2 in conjunction with a C2A2 Support Weapons Sight can provide battalion-level direct support fire at ranges up to {{convert|1800|m|yd|0|lk=off|abbr=on}} and indirect map and range table predicted support/harassment fire out to {{convert|2500|m|yd|0|lk=off|abbr=on}}. The indirect firing method exploits the 7.62×51mm NATO useful maximum range, that is defined by the maximum range of a small-arms projectile while still maintaining the minimum kinetic energy required to put unprotected personnel out of action, which is generally believed to be 15 kilogram-meters (147&nbsp;J / 108&nbsp;ft⋅lbf).<ref name="krtraining1">{{cite magazine |author1=Kjellgren, G.

The ''L8A2'' [[coaxial weapon|coaxial]] [[tank]] machine gun (replaced the L8A1) has a different gas valve switch (closed, single-position) when compared to the analogous Model 60-40, a different flash hider and a modified cocking handle. The weapon also has a trigger group that accepts electrical input and a lever in the feed tray that enables the belt to be removed without lifting the feed tray cover.

Another tank machine gun is the ''L37A2'' (succeeded the L37A1) designed to be mounted on tank turrets, in the commander's position, on wheeled armoured vehicles and on [[armored personnel carrier]]s. It differs from the L8A2 primarily in its trigger, which was adapted from the L7A2 GPMG. The machine gun can be used in the ground role for self-defense, by dismounted vehicle crew members, the ''egress kit'' consists of an L7A2 barrel, bipod and buttstock.

The ''L20A1'' aircraft machine gun was based on the L8A2, from which it differs by having an electrical trigger and a slotted flash suppressor. The L20A1 can be converted to right-hand feed by changing several components in the feed mechanism.

The ''L43A1'', also developed from the L8A2, is a coaxially mounted tank machine gun used to sight-in the vehicle's main gun by firing ballistically matched [[tracer ammunition]] at the target to confirm the trajectory visually. The weapon's barrel, fitted with a flash hider, has a reinforced and heavier structure that increases the weapon's accuracy especially during sustained fire.'

The C6 GPMG is also mounted on a variety of vehicles, including the G-Wagon LUVW, LAV 6.0, TAPV, Leopard 2, and CH-146 Griffon helicopter. In these vehicles, the C6 GPMGs are co-axially and pintle-mounted and used to provide fire support to the infantry or for local defence of the vehicle itself. On the TAPV and LAV 6 ACSV, the C6 can be mounted on an RWS platform. In September 2018, Canada began fielding an improved '''C6A1 FLEX''' version; changes include a polymer buttstock which is more durable and easier to decontaminate in a CBRN scenario than the original wooden stock, M1913 [[picatinny rail]]s for the attachment of pointing devices and optical sighting systems, and an adjustable gas tube regulator to control the rate of fire.<ref>{{cite web|url=https://www.all4shooters.com/en/Shooting/pro-zone/C6A1-FLEX-new-machine-guns-Canadian-armed-forces/|title=New C6 machine gun for Canadian forces |website=all4shooters.com (EN)|date=4 September 2017 |accessdate=17 April 2018}}</ref><ref name="canadaca">{{cite web |title=C6 and C6A1 7.62-mm Medium Machine Gun |url=https://www.canada.ca/en/army/services/equipment/weapons/c6-general-purpose-machine-gun.html |publisher=[[Government of Canada]] |access-date=3 November 2022 |archive-url=https://web.archive.org/web/20220831180402/https://www.canada.ca/en/army/services/equipment/weapons/c6-general-purpose-machine-gun.html |archive-date=31 August 2022 |date=16 February 2021 |url-status=live}}</ref><ref name=coltcanadapresser>{{Cite web |url=https://www.coltcanada.com/assets/colt-canada-c6a1-release.pdf |title=New C6A1 Flex General Purpose Machine Guns for the Canadian Armed Forces |access-date=2018-04-15 |archive-date=2018-07-31 |archive-url=https://web.archive.org/web/20180731000045/https://www.coltcanada.com/assets/colt-canada-c6a1-release.pdf |url-status=dead }}</ref><ref name=janes>{{cite web|url=http://www.janes.com/article/72659/canada-buying-new-7-62-mm-general-purpose-machine-guns|title=Canada buying new 7.62 mm general purpose machine guns - Jane's 360|website=www.janes.com|accessdate=17 April 2018|archive-url=https://web.archive.org/web/20180416073512/http://www.janes.com/article/72659/canada-buying-new-7-62-mm-general-purpose-machine-guns|archive-date=16 April 2018|url-status=dead}}</ref><ref>{{cite web|url=http://www.guns.com/2017/07/28/canada-to-get-1148-new-improved-c6a1-machine-guns/|title=Canada to get 1,148 new, improved C6A1 machine guns|date=28 July 2017|publisher=|accessdate=17 April 2018 |url-status=dead |archive-url=https://web.archive.org/web/20180731062202/https://www.guns.com/2017/07/28/canada-to-get-1148-new-improved-c6a1-machine-guns/ |archive-date=31 July 2018}}</ref><ref>{{cite web|url=http://www.forces.gc.ca/en/business-equipment/c6-general-purpose-machine-guns.page|title=C6 General Purpose Machine Guns (GPMG)|publisher =Government of Canada  |website=www.forces.gc.ca|accessdate=17 April 2018}}</ref> The C6A1 is manufactured by [[Colt Canada]], with the company having earlier provided support for the original C6 fleet, and is the first support machine gun to have been manufactured in Canada since the Second World War.<ref name=coltcanadapresser />

===German versions===
The German arms manufacturer, [[Heckler & Koch]], whose 1999 to 2002 owner [[BAE Systems]] — as the result of a 1999 merger between British Aerospace and Marconi Electronic Systems, Heckler & Koch was owned by the resulting BAE Systems — had executed a midlife improvement program of the L7A1 (FN MAG 60.20 T3) to the upgraded L7A2 (FN MAG 60.20 T6) version under contract for the British Ministry of Defence, attempted to make their own variant of the FN MAG. It was designated the HK 221.

This version is equipped with an iron sight line that consist of a rotary rear drum and hooded front post and Picatinny rail atop the receiver. It was meant to compete in the machine guns trials held by the German and French military between 2007 and 2008. The trials concluded with the French military selecting the original FN MAG in 2010, while the German military selected the [[Heckler & Koch MG5]] in 2015.<ref>{{Cite web|url=https://modernfirearms.net/en/machineguns/germany-machineguns/hk-221-eng/|title=HK 221|date=August 12, 2011|website=Modern Firearms}}</ref>

===Swedish Army versions===
{{Main|Ksp 58 machine gun}}

All versions are licence-manufactured by [[Bofors Carl Gustaf|FFV-Carl Gustaf]].
The Swedish abbreviation for ''kulspruta'' (machine gun, lit. "bullet sprayer") is ''Ksp''. ''Strv'' is the abbreviation of ''Stridsvagn'' (battle tank).

[[File:Ksp58.jpg|thumb|A left-side view of the Kulspruta 58B (Ksp 58B).]]

'''Kulspruta 58''': Ksp 58, adopted in 1958 using the [[6.5×55mm]] [[rifle]] cartridge which at that time was the standard cartridge in the Swedish Army.

'''Kulspruta 58 B''': In the early 1970s, the weapon was modified with a new gas regulator and at the same time the barrels were replaced to the new standard [[7.62×51mm NATO]], same as used by the [[Automatkarbin 4#Variants|Ak 4]]. Ksp 58 replaced the considerably heavier [[kulspruta m/42|Ksp m/42B]] in the infantry units. It can be fed with non-disintegrating DM1 or disintegrating [[M13 link]]ed ammunition belts.

'''Kulspruta 58 C''': On [[Combat Vehicle 90]], this version replaced the previously used [[MG-4 machine gun|Ksp m/39]] in the third quarter of 2004.

'''Kulspruta 58 Strv''': stripped variant mainly used for fixed mounting in tanks. Phased out along with [[Stridsvagn 103]].

'''Kulspruta 58 D''': Reserved designation for the renovated and modified Ksp 58B. The trial version is referred to as 'Ksp 58 DF', where the 'F' stands for 'Försök' (Experimental).

* A MIL-STD 1913 [[Picatinny rail]] system added. Half of the weapons feature an adjustable rail - the others a fixed.
* Red dot sight ([[Aimpoint AB|Aimpoint]] CompCS).
* The carrying handle is shortened to half its original length. This was necessary in order to fit an extended rail for sight systems.
* Cbuttstock butt stock or folding stock.
* 100&nbsp;mm shorter barrel.
* Better and shorter flash hider to reduce the length of the weapon and to produce a smaller muzzle flash, which means less disruption to the user's night vision.

On January 14, 1977, the US Army awarded a contract to FN Herstal for the delivery of a modernized Model 60-40 variant tank machine gun designated the ''[[M240]]''. Initially, the firearms were produced in Belgium. Currently they are manufactured in the US by FN's US wholly owned subsidiary FNMI (FN Manufacturing Inc.) located in [[Columbia, South Carolina|Columbia]], [[South Carolina]], and by [[U.S. Ordnance]] in McCarran, Nevada.

The M240 is built in several versions:
* '''M240''' standard coaxial machine gun used in US armored vehicles. It is used in the [[M60 Patton|M60]] series of tanks (where it replaced the [[M73 Machine gun|M73/M219]] 7.62&nbsp;mm machine guns) and the [[M1 Abrams]] family. It has an electrically operated trigger and a reloading lever. Compared to the MAG Model 60-40, the M240 has a different flash hider and gas valve.
* '''M240B''' is a modernized derivative of the M240G, which features a perforated hand-guard and heat shroud, a [[Picatinny rail|MIL-STD-1913 rail]] integral with the receiver top cover, which enables the use of optical day and night sights, a new synthetic stock and a new ammunition container. It was selected to be the [[United States Army|U.S. Army's]] new medium machine gun on December 1, 1995, replacing the M60 machine gun - it defeated the M60E4 during trials. M240Bs are also replacing M240Gs in USMC service. The M240B weighs {{convert|12.5|kg|lb|abbr=on}} and has a length of {{convert|1245|mm|abbr=on|1}}. The rate of fire is 650–750&nbsp;rounds/min.
* '''M240C''' with a right-hand feed system. It is used in the [[M2/M3 Bradley Fighting Vehicle|M2]] and [[M2/M3 Bradley Fighting Vehicle|M3 Bradley]] series of [[infantry fighting vehicle]]s as a coaxial gun to the main armament.
* '''M240D''' an upgrade of the M240E1 and is optimized for use in military helicopters in a pintle-mounted configuration. The M240D is also supplied with an egress kit for dismounted use.
* '''M240E1''' installed since 1987 on [[LAV-25|LAV]]-series wheeled armored fighting vehicles, has a spade-type grip with an integral trigger and cocking mechanism.
* '''M240G''' introduced into service with the [[United States Marine Corps]] and the [[United States Army Rangers|75th Ranger Regiment]] in the mid-1990s in place of the [[M60 machine gun|M60E3]]. The M240G is used on the M122A1 tripod for stationary use, and is also used in vehicular and aircraft mounts. It weighs {{convert|10.99|kg|abbr=on}},<ref name="Modern Firearms - FN MAG">{{cite web |url=http://world.guns.ru/machine/be/fn-mag-e.html |title=Modern Firearms - FN MAG |publisher=World.guns.ru |date=2010-10-27 |access-date=2012-07-30 |archive-url=https://web.archive.org/web/20120604024026/http://world.guns.ru/machine/be/fn-mag-e.html |archive-date=2012-06-04 |url-status=live }}</ref> has an overall length of {{convert|1245|mm|abbr=on|1}} and a rate of fire of 650–950&nbsp;rounds/min.
* '''M240H''' an improved version of the M240D. The M240H features a rail-equipped feed cover, an improved flash suppressor and has been configured so it can be more quickly converted to infantry standard using an Egress Kit. The M240H is {{convert|41.2|in|mm|abbr=on}} long, has a {{convert|23.6|in|mm|abbr=on}} barrel, and has an empty weight of {{convert|26.3|lb|kg|abbr=on}}.
*'''M240L''' is a development of the M240B reduced in weight by {{convert|5.5|lb|kg}}. The weight savings on the M240L are achieved by incorporating titanium and by using alternative fabricating methods for major components. A short barrel and collapsible stock are available.
