Ahhh, the FAL doesn't have a free floating barrel, it is heavy as hell, mounting modern optics is complicated, and the L129 has the ability to quickly change barrels
for long distance shooting.
So the FAL while an improvement on long range shooting over the L89, a modern sharpshooter rifle is much better.
