Yes the FAL but known in UK, Aust, NZ, and I think Canada as the SLR.

What I now find a more than a little amusing is that back in the early 80's I pointed out all the pitfalls of the 5.56 to our Director of Infantry. Needless to say, he disagreed although there was evidence then to back up what I was saying. Now there is way more evidence to back this up.

I think it is the correct move. The extremely high pressure 270 (6.8mm) cal the US is going to is just asking for problems. Not because of bore size but construction of the ammunition especially if the west end uop in a shooting match with China.
