L7 (machine gun)

From Wikipedia, the free encyclopedia

The L7 machine gun general purpose machine gun is used by the British Army. It and the related L8 are a licence-built derivative of the Belgian FN MAG (Fabrique Nationale Mitrailleuse d'Appui Generale 1958) machine gun firing the standard 7.62 mm NATO cartridge.

The official British Army designation is L7A2 GPMG (General Purpose Machine Gun), but it is affectionately nicknamed "Gimpy" by British soldiers. The L7 replaced the long-serving Vickers machine gun.

The L8s are modified designs that make them suitable for use in vehicles.

[edit] History

The FN MAG was one of several weapons considered for use as the Army's suppressive fire weapon. Over a period of a year it was tested alongside the US M60, two designs by the Swiss firm SIG, the then MAG design and a design by RSAF Enfield, a conversion of the Bren gun to belt feed. Alongside the other candidates, the MAG was considered in the top two alongside the Enfield design. Work on this was dropped and the MAG selected. Modifications to the basic FN design were incorporated and it entered service as the L7A1. Subsequent modifications led to the L7A2. Because one of the requirements was for heavy supressive fire, something the Vickers machine gun excelled at, a heavy barrel was designed for the gun for this role. A number of these were supplied at company level and could be issued to the platoons as necessary.

The nature of the MAG design made it inherently unsuitable in an unmodified form for use within vehicles. The major changes required were a means to take the vented gas outide the vehicle and to enable belt feed from either side in possibly cramped conditions. The former was solved by a modification to the muzzle - a simple tube drew the gas exhaust from the regulator area forward.
