I've been using the MOE SL stock for years with no real complaints. Does what it should, doesn't get in the way.
On my A2 carry handle rifle I like using a Vltor EMod. The wider stock seems to work well with iron sights. I don't like it when using a magnified optic though.
I was very surprised when I borrowed a friend's rifle recently. His stock felt great, and I was shocked to see "FAB Defense" stamped on the side of it:

The toe works well for bringing the rifle up and transitioning. I only shot it offhand and didn't try any long range or prone work, but I was genuinely surprised at how much "better" it felt than my normal MOE SL stock.
