Glad you liked the pics. I seem to remember one of the stocks breaking when we did our initial T&E of the weapons. The issue was that something came apart and allowed the stock to come completely off, i.e. the piece with numbers on it could be separated from the rest of the rifle. I can say that I abused the crap out of my stock and didn't have any problems. If I owned a SCAR I wouldn't worry about the stock too much. If you run over it with a truck or something I'm sure FN will replace it for you. I think Vltor or someone is making an M4 stock adapter if you don't trust the factory one, but I don't see a reason to not trust it.
