In August 1934, after a 50000-round endurance test, the BRNO ZGB 34 LMG was adopted by the British Armed Forces. The licensing arrangements with Ceskoslovenska Zbrojevka Brno permitted the manufacture of a new gun, designated as BREN (for Brno and Enfield), at Royal Small Arms factory in Enfield. the first Bren Mark 1 light machine gun, left the Enfield factory in September 1937.

During WW2, Bren guns were also made in Canada, by John Inglis Co., and in Australia, by Lithgow Small Arms factory. The Bren machine guns proved to be highly effective, reliable and very accurate weapons, but the Bren guns were gradually simplified and lightened, resulting in a series of Marks, from Mk 1 to Mk 4. At the same time, the Inglis Company, in Canada produced a number of Bren guns in 7,92 Mauser calibre for China.

When Britain has jointed the NATO in 1954, it solved the problem of the light machine gun in new standard caliber (7,62x51mmNATO)by simple adaption of the Bren to the new cartridge. These "NATO standard" Bren guns received official index L4A1, which went through a number of modifications during it's service in the British Armed Forces, the final model produced being the L4A9.

The L4 BREN LMG is a gas-operated, air cooled, selectively fired machine gun. It has a quick-detachable barrel The action of gun is powered by a long-stroke gas piston, located below the barrel.

The ammunition feed is from top-mounted box magazines. These are made from sheet steel and hold 30 rounds in a two-row configuration (although in the field soldiers preferred to load only 27-28 rounds to reduce strain on the magazine spring and thus ensure reliability of the feed under harsh conditions). The magazine housing has a sliding dust cover which is slid forward to load the gun. Spent cartridges are ejected downwards. The ejection port is normally closed with its own dust cover which opens automatically once the trigger is pressed. The trigger unit permits both single shots and automatic fire, selectable through a safety / fire mode selector lever situated at the left side of the pistol grip.



General Purpose Machine Gun

Effective Range:800-1800m Date in Service:1954

The MAG (Mitrailleuse d'Appui General = General Purpose Machinegun), had been developed by the famous Belgian company FN Herstal in the 1950s, as a true universal machine gun, that could be used as a light MG on bipod, as a medium MG on tripod or as a vehicle-mounted MG. The basic design of the MAG is no more than a time-proven Browning action, taken from the M1918 BAR automatic rifle, turned upside down and adopted for belt feed. The basic design used as much steel stampings and pressings as possible to save the labour and costs, and the final gun had the angular, but very business-like appearance.

L7A2 General Purpose Machine Gun



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 and the Bren in 1957.

Built under license originally by Royal Small Arms Factory, Enfield and currently by Manroy Engineering, it serves in the British Army, the Royal Marines 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 (redesignated the L4) continued in use, 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 sustained fire capabilities and reliability resulted in units continuing to utilize the L4 & L7 whenever possible. The British Army and Royal Marines have since been issued with the L110A1 (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.

L7A1 General Purpose Machine Gun



In 1961, the Royal Small Arms Factory, Enfield, undertook production of the MAG in the following versions: L7A2, L8A2, L37A2, L20A1 and the L43A1, using the M13 ammunition belt.
The L7A2, GPMG, replaced the L7A1 in service with the British Army, featuring minor changes. These were, a 10-position gas regulator valve, a plastic butt-stock and a bracket, used to mount optical day/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 periscope sight.

The L8A2 coaxial tank machine gun (replacing the L8A1), has a different gas valve switch (closed, single-position), 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.

The L37A2 (replacing the L37A1), is designed to be mounted on tank turrets, in the commander's position, on wheeled armoured vehicles and on armoured personnel carriers. It differs from the L8A2, in its trigger group, 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, an egress kit is issued with the weapon, consisting of an L7A2 barrel, bipod and buttstock.

The L20A1 aircraft machine gun is based on the L8A2, but differs by having an electrical trigger and a slotted flash suppressor. The L20A1 can also be converted to right-hand feed.

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 L7/L8 is an extremely reliable and proven design, that seen widespread service, being adopted by many armies around the world.
An inoperative, drill version was was produced designated L46A1.
