United Kingdom
The Bren is considered to be one of the finest machine guns ever designed despite being a magazine-fed weapon. The Bren was a light machine gun intended to replace the previous Lewis Gun. Developed and put in production in 1935, BREN Mk.1 was a near identical copy of the Czech ZB-26, customized for United Kingdom standards and requirements (most notable - .303 British ammo). The Bren had a reduced rate of fire and heavy weight to aid controlability. The Bren was know to be reliable, but it had issues like barrel overheating too fast and the fact that it was magazine fed. BREN had stayed in service until 1991 where it saw service during Gulf War 1. Though officially, BREN is no longer in service, British Army and Navy still have a substantial number of L4A4 and L4A6 in stock. Additionally, BREN guns are still in use in countries which imported British weaponry, like India where it is manufactured as the Machine Gun 1B.
