On a side note, I've seen this documentary and it's pretty good. I am drooling to own a TAR-21 , unfortunately it's doubtful we will get them in the US due to the import laws.
I still believe the Galil is a AK47 made right, and one of the best improvements to a AK47 in recent history. I love the Galil, but I can see a little bit how troops say it is too heavy. The South African Defense Force used to run around with the Galil on their backs or holding it above their head and in uncomfortable positions, even showered with them to get used to the weight.
