The X-11 GPMG was an experimental general purpose machine gun designed and manufactured by RSAF Enfield.


The X-11 was designed in the 1950s at Enfield as a general purpose machine-gun for use with the British Army. At the time, the British Army was looking for a belt-fed machine gun similar to the German MG42, since the L4A4 Bren was not adequate as a GPMG. The X-11 was a rather hurried attempt to meet the Army's requirements; it was essentially a Bren converted into a 7.62 belt-fed support weapon. The X-11 was entered into British Army trials in 1957, where it competed against the X-16 made at Birmingham Small Arms, the Belgian FN MAG, the American M60, the French AA-52, the Danish Madsen-Saetter and the Swiss SIG MG55. The X-11 proved itself a worthy opponent to the FN MAG, but the MAG was ultimately victorious in the trials and was later adopted as the L7A1 GPMG. The X-11 project was abandoned a year later, in 1958.
