Looking for input here. I was drooling on a FS this weekend, I like the idea of shooting off left or right side, the size is great, but what about mags working correctly, stock and part durability. My AUG is a great gun, but don't shoot lefty, and only one optic. looking to part with it to get a FS. Am I insane for considering that? I love my other FN stuff, FAL, FNC, PS90, High power. does the FS live up to its family line?
