My MCX Canebrake has a folding stock -- er, I mean, pistol brace. I'm not sure I see a lot of utility. Obviously it makes for a smaller package for storage/carry, but I'm not that crazy about shooting it with the stock folded. I mean, it's fun to do so, but I don't know that I would do so defensively. I don't have a lot of expertise, so I might be missing something on that front.
