L1A1

The L1A1 (popularly known as the SLR) was a British gas operated semi-automatic rifle based upon a modification of the Belgian FN FAL rifle. The L1A1 was chambered for the 7.62 mm cartridge which it took from a 20-round box magazine and fired at a muzzle velocity of 838 meters per second to an effective range of 600 meters. The L1A1 had a 554 mm long barrel and was fitted with a trilux foresight and an aperture rearsight.
