The UK adopted the FAL as the L1A1 SLR (Self Loading Rifle), and included a number of improvements and modifications. The most important of these is the SUIT (Sight Unit, Infantry, Trilux) 4x magnification sight. The SUIT features a prismatic offset reduces the length of the scope and improves clearance around the action of the rifle. Although heavy, the SUIT is noted for its durability.
The FAL has a magazine capacity of 20 rounds, and weighs 4.45kg empty. It has a rate of fire of 650-700 rounds per minute.
