Large Mag for CZ 550?

[PieFace]

I was thinking of getting a CZ 550 Varmint Kevlar in .308. I understand this has a 4 round detachable mag, can you get a larger mag for this rifle, does anyone know if the 10 round CZ 750 mag fits the 550?

I did read somewhere that the 750 was just a 550 that had been pimped up.

Many Thanks...
