Outwardly, the L1A1 featured a conventional layout made up largely of the receiver containing the critical internal working components. The ejection port was set to the right side of the body. The pistol grip was ergonomically formed and integrated into the ring-guarded trigger system. The magazine well was just ahead of the trigger group and accepted the standard 20-round straight detachable box magazine consistent with (though slightly different from) the FN FAL. A 30-round magazine count was also made available. The weapon was chambered for the 7.62x51mm NATO standard rifle cartridge and its action centered around the gas-operation principle with a tilting breech block. As such, the forward handguard housed the gas cylinder over the barrel, the latter extended well ahead of the gun and capped by a slotted compensator. The gas cylinder was used to tap gasses of fired rounds and return them within the recoil process, ready to fire the next available cartridge in succession. The L1A1 was, therefore, also known as the "Self-Loading Rifle", or SLR, to indicate its repeat-fire action. The stock was fixed and there were sights at the rear of the receiver as well as the extreme end of the forward handguard. A positional grip-covered carrying handle was set to the left side to help facilitate transport. The original L1A1 production form was semi-automatic fire only. The upcoming L2A1 featured a full-automatic fire mode function which broadened the weapon's tactical usefulness.
