I am excited to see a Tikka chassis - It looks like it is very modular by design... and noting how much aftermarket support Tikka has, I would suspect before too long there will be a ton of aftermarket options to customize this exactly how you want it. It looks like a carbon fiber forend and a different stock setup would all be very possible.
I have been looking for a .223 chassis setup to plink with, this may be what I purchase. If you were to ask me why.. simple, I like Tikka, I already own several, I use the tikka magazines, it would allow to me swap to any other caliber if wanted... makes my life easy.
