The L7A2 GPMG - General Purpose Machine Gun BRITISH ARMY The L7 general-purpose machine gun is still used by the British Army. 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, it serves in the British Army, the Royal Marines and other services. There have been 2 main variants, the L7A1 and L7A2, developed for infantry use, with the L7A2 having superseded the earlier variant.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 7.62x51mm 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 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 and Royal Marines were issued with the L110A2 (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 ammunition as the 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 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, a 10-position gas regulator valve, a polymer butt-stock and a bracket, used to mount optical day- and night-vision sights, mounted to the left side of the receiver. In a stationary (defensive) 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 Machine Gun Platoon the L7A2 in conjunction with a C2A2 Support Weapons Sight can provide battalion-level direct support fire at ranges up to 1,800 m (1,969 yd) and indirect map and range table predicted support/harassment fire out to 2,500 m (2,734 yd). The L8A2 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 carriers. 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. .
