The L98A1 was a piece of junk and was probably more dangerous than giving cadets L85's.
While cocking the weapon, if it didn't fall apart as has been previously mentioned, it had a habit of making the end of the barrel rise above the target line on the range. Sometimes even above the wall behind the range.
The biggest advantage of the L85 was the SUSAT sight, and now the ACOG or ELCAN sights that really improve the accuracy. From just being able to hit the target at 300m, now you can choose where you want to hit them, if you have the time.
