Backpacker X-22 Mount

Im looking at picking up a backpacker, I want to buy the magpul x-22 mount with it however magpul says they aren’t compatible with the adjustable fiber optic sights. It appears that every version that comes from the factory with the magpul stock has the adjustable fibers. Does anyone know if they actually are compatible?

I’m not going to buy a different takedown and buy a magpul stock separate just so I can use their mount
